Custom Cable Tester

Cable tester, custom design for cable harness assembly production.

Custom cable tester electronic kit

An operator can just simply plug in the cable connector to the tester to check for the cable harness assembly automatically.

An audible beep will be sound immediately after the operator plug-in the connector. This indicates that the cable’s wiring is correct. The operator can simply focus their vision on the manual connection work.

If there is no sound heard after plugging in, the cable’s wiring is probably incorrect or faulty. There will be LED indicator (orange colour) for each of the respective wiring. If any LED remains lighted up after plugging in the connector, they indicate a wiring fault. The fault due to the following,

  • incorrect pin connection.
  • the wire break resulting in a broken electrical connection.
  • the connector is not properly crimped or soldered.

Wire harness connection tester device

This custom tester has a monitoring mode which is designed to catch intermediate break wire connection that may be potentially existing in your the cable assembly. Intermediate wire connection fault can be due to a broken wire or cable that is not properly assembled. The fault may occur when the cable is touched or bend too much.

When all the connectors are connected to the cable tester, the tester will automatically enter into a monitoring mode. You should be able to hear 2 special beep sound which indicates that the tester is now in the monitoring mode. In this mode, all connectors are connected to the tester. Any connection break in the process of monitoring will trigger an error from the cable tester device.

To test your cable assembly in this mode, you can simply shake up the whole cable. The shaking can help to bring out any intermediate connection problem if there is any. You should see an error LED indicator (Red) lights up together with a long Error tone if an intermediate connection break is detected. The respective wire connection indicator (Orange LED) will also be displayed to indicate the exact wire that is having the intermediate connection problem.

Features of the Cable Tester [PIC-023]

Wire connectivity indicator lights up for faulty wires

  • Simple to use.
  • Instant audio beep and flashing LED light (Green) when the cable is plugged in, to indicate that the cable has passed the checking.
  • LED indicator (Orange) will remain lighted to pinpoint faulty wires
  • Able to catch potential intermediate connection fault in the cable.
  • LED (Red) and long buzzer tone to indicate detected cable problem.
  • Portable and can be designed to power up from USB power supply or from the battery.

Operating Procedure

Test for intermediate cable connection fault

  1. Plug in USB power cable, or insert batteries.
  2. Switch on the cable tester to power up. A test sequence will run to show that the buzzer and all the LED are working.
  3. Plug in one side of the cable onto the tester.
  4. Plug in the other side of the cable. The cable tester will detect the connection and begin testing the cable.
  5. A double beep sound and flashing Green LED indicates that the cable is tested ok.
  6. The respective LED indicator (Orange) for each of the wiring will diminish if the connection is mated correctly.
  7. If there is no sound heard after plugging in the cable, the cable is probably faulty. Check on the respective wire indicator (Orange LED) to determine the exact wire that is faulty. 1 or more LED should be lighted up which indicates incorrect or no connection.
  8. After the cable is all connected to the cable tester and has passed the wire connection test, the tester will enter into a monitoring mode. You should hear 2 special beep, followed by a blinking light from the green indicator, which tells you that the tester is now in the cable monitoring mode.
  9. In this cable monitor mode, you can continue to test the wired connection of your assembled cable harness. Shake your cable to see if there is any intermediate connection fault can be caught. If a glitch is detected due to the intermediate connection break, the cable tester device will be able to catch it. A long beep and error indicator (Red LED) will be lighted up. The respective wire indicator (Orange) will also be lighted up to pinpoint the exact wire that is causing this intermediate connection problem.
  10. The caught wire glitch fault will remain until all the wires are disconnected. The cable tester will then reset the test procedure.
  11. The operator can proceed to test the next cable harness set.

Other Optional Specialised Test Features

For dedicated wiring for precision/importance use, there are optional test that we can design to help you detect potential faults in your cable harness wiring.

The following are some of the specialised test that you may need to test on your assembled cable beside the basic connectivity check.

  • Ohm test or resistivity test for your wires and connectors, to check if the wires are crimped or fasten properly.
  • High voltage test, to ensure the wires are properly insulated.
  • High-speed data or RF test to ensure signal integrity quality of your assembled cable.

Electrode Water Level Sensor

*** Scroll down to the bottom of the page for the
purchase of this water level sensor and its metal rods.

Electrode water level sensor is also known as a “Conductivity Level Sensors”.

Electrode sensor basically requires physical contact with the water to detect the water level. The water act as resistance. Small electronic current will be passing through the water which helps the sensor to sense the water level. For this reason, not all liquid can use this sensor for detection. One example is oil, which has an insulating property in nature. If you need to measure the level of a non-conducting liquid, consider using an ultrasonic water level sensor.

For a typical water tank or rainwater level detection, the electrode sensor is an affordable and commonly used method to detect the amount of water in a tank compared to other water level sensing method.

Electrode Sensor for Water Level Detection

An electrode sensing needs at least two contact point to function. For electrode with only a single probe, the other end of the sensor wire will be connected to a metallic tank (usually of stainless steel material). The metallic tank will act as the second probe. If the tank is not metal, or you do not want to connect the sensor wire to your tank, you can use a two probe electrode.

For multiple water level detection, you will need more probes. You can place up to a maximum of 5x probe for 3-4 water level detection. If you need to differential more water levels, you may like to consider using an ultrasonic water level sensor which can provide a higher resolution of detecting the water level.

Ultrasonic Water Level Sensor

This page introduces using water level detection solution in a water tank using ultrasonic sensor.

Ultrasonic water level sensors

Ultrasonic sensor (similar to radar and sonar) is using acoustic means for detecting an object’s distance away from the sensor. Just like a bat, the sensor will generate an acoustic pulse. The radiated pulse will hit the targetted object and reflected back to the sensor. The time taken for the pulse to echo back to the sensor provides an estimation of a distance. Knowing that the speed of sound is constant (in an acoustic medium) the detected distance can be relatively consistent.

Features For Water Level Detection

Sensing Distance

Sensing distance for water tank application typically ranges from 1 to 5 meters. If further detection distance is required, the sensor will need more energy and a bigger acoustic surface to emit and receive the ultrasonic pulse. This means the ultrasonic sensor for water level detection is usually bigger in size.

The increase in sensing distance also affects the sensing speed (sensing frequency). For water level detection, detection speed usually is not an important issue.

  • Sensing distance typically (1 to 5m)
  • Dead-zone (0.2 to 0.6m)

An ultrasonic sensor is typically designed for a certain detection range for a specific application. This helps to eliminate the possible noise being reflected from the environment. This is especially noise within a confined space like a water tank. The trade-off for a robust ultrasonic sensor will result in a slower detection speed. Dead-zone is the near range region which the ultrasonic sensor cannot detect. It is a blind spot to the sensor.

Output Type

There are many types of output to choose from. A benefit of using ultrasonic sensor is its ability to measure the relatively distance or water level in a water tank. For this reason, most of the time we want an ultrasonic sensor that can provide us with an analogue output or is able to output digital data. An analogue output provides distance information for our water tank level application.

  • Analogue output (0-10V, 4-20mA)
  • Digital data. (example RS232, RS485)
  • Electromechanical relay output (dry contact, normally opened, normally closed)
  • NPN, Open Collector output

Relay (dry contact) or NPN output can only provide simple on/off information. It can only tell you if the water level is reached or not.

Power Supply Input

There are typically two types of power input (either DC or AC voltage) to the sensor. It is recommended to select an ultrasonic sensor using DC voltage supply for a water tank application. If water gets in contact with the DC power will only result in minor water/gas reaction.

High voltage 230Vac power touching the water can be a safety hazard. If using DC powered ultrasonic sensor is not a solution, you should earth the water or water tank as a protection. In case the power line touching the water, the electrical system will be tripped and shut down as a means of protection.

  • 12Vdc or 24Vdc
  • 230Vac

Product Housing

For normal water tank application, you can just use a normal ultrasonic sensor. If you are using the sensor under a stressful environment, you may like to consider getting a sensor that can withstand water or even chemical resistant.

  • Waterproof (IP65, IP67)
  • Chemical resistant
  • Robust from microbial contamination

Teflon coating can protect the transducer from most types of chemical. For bio-sensitive labs or production line hygiene, you may even want to use stainless steel ultrasonic sensor (very smooth and polished surface) that can minimise the risk of microbial contamination.

Other Features

The installation location of an ultrasonic sensor can be sensitive. This is especially for installation within a water tank where multiple acoustic reflections can occur. It is best to install away from the wall. The narrow acoustic beam can also help to reduce the unwanted reflection.

  • Easy to mount and deploy.
  • Simple to configure.
  • Programmable.
  • Status and indicators.

Water Level Float Switch Sensor

A float switch is a simple switching device which gets triggered when it is being lifted by the water/liquid. The float is designed to be less dense than the liquid, allowing it to float up when in contact with the liquid.

Float switch requires maintenance once in a while. For a liquid that is too dense, or sticky, it is not advisable to use a float switch. You may like to consider using an ultrasonic water level sensor instead. An

Common Application

  • Automatic replenish water tank
  • Fish tank water cycling
  • Rain-water tank and drainage control system
  • Water reservoir or Ponds
  • Tracking water drainage system

Please click on the images to the respective product links.

A magnetic float switch is one of the most popular float switches in the market. It is simple and easy to install. The sensor has a minimum number of moving mechanical parts compare to other float switches, which means the probability of sensor failure is lesser.

The magnetic float switch uses a reed which is typically very small in size. The floating compartment is inserted with a small and strong NEO magnet. When the magnet is close to the reed switch, the switch will make a contact (activate short circuit).

The entire sensor can be small in size and light in weight because of the small component used.

  • Small in size
  • Small dry contact relay
  • Come in plastic or stainless steel material

If the liquid in the water tank requires cleanliness or hygiene, there are stainless steel water level float switch available. For simple water tank application, a plastic version is good enough. If you do not want the sensor to be in contact with the sensor for potential contamination happening, you may like to consider using an ultrasonic water level sensor instead.

One disadvantage of this magnetic float switch is that you cannot use the switch itself to drive a high current load. The most current you can drive through this sensor is probably about 100 to 300mA. If you need to drive a high current device using this sensor switch, you will need to interface it with an additional relay.


Mechanical Ball Float Switch

A mechanical ball float switch consists of a weighted ball and a micro switch built inside the housing. When the water level reaches the sensor, the sensor will start to float upwards. This upward position will roll the ball downwards with the help of gravity. When the ball rolled down, it will trigger and depressed the microswitch inside the sensor housing.

Mechanical Ball flow switch    Omega logo

  • Switch can conduct higher current
  • Bigger in size
  • Suitable to be used in a large tank or big ponds/rivers.

The sensor is usually bigger in size due to its trigger mechanism. The micro switch is bigger in size and is able to drive a higher current load (small motor) without using external relay interface.

Due to its dangling wire design, the sensor need not be secure at the required water level height. This is unlike the magnetic sensor as introduced earlier. This sensor can be pivoted to the side or bottom of the pond. When the water level reaches the height, the sensor will float up and the micro switch (dry contact) will be triggered.

Bilge Pump Float Switch

This is a bilge pump float switch which is a commonly used water sensor inside a boat yacht. Float water inside the boat hull will trigger this sensor. The sensor will run a bilge motor to pump the trapped water out of the boat/yacht into the open sea.

This bilge pump is specially designed for the marine industry. The material used in this sensor resist better under in a corrosive sea environment.

Lowest Cost Water Level Sensor

The magnetic float switch is a widely used as a water level detection sensor. It is simple and is mechanically driven. The float switch consists of a float, magnet and a reed switch which are fairly inexpensive.

The reed switch which will be activated when the magnet is near. The activated reed switch will form a dry contact which indicates that a water level is reached.

The disadvantage of a float switch is that it has to be in contact with the liquid in order to function. For this reason, high-density liquid will not be suitable (one example is thick oil). The float switch also comes with a stainless steel version instead of plastic.

The sensor is rather reliable due to its simple mechanism. It is also a recommended secondary sensor to install for safety purpose even if you are using other methods of water detection.

A magnetic float switch is a simple and reliable.

Water Level Sensor with Analog Output

The ultrasonic sensor (acoustic sensor) is suitable for applications that require the detection of the water level depth in a tank or the amount of water in the water tank. The water level detected has a higher resolution. This wide water level detection range is also known as a water level sensor with “analog output”.
