Liquid Level Sensors

An innovative, cost-effective solid state Liquid Level Sensor

TestWorks Group develop and manufacture an innovative, cost-effective range of solid state liquid level sensors.

The sensors have been designed to offer liquid control in a wide range of applications in the Automotive, Medical, Food, and Chemical industries, and work on the principle of Total Internal Reflection using infrared LEDs and detectors. This means that there are no moving parts in the liquid and the colour and density of the liquid is not significant. Customisation is possible to achieve optimum performance for specific liquids.

Liquid Level Sensor

The sensor tube is made from FEP (Fluorinated Ethylene Propylene) for optimum chemical resistance, with a stainless steel header for strength. Alternative materials can be selected for individual applications. Due to its chemical resistance, these sensors are suitable for aggressive liquids, including acids.

  • Manufactured up to 2 metres in length
  • Measurement resolution of 2mm
  • Requires only a 12V-24V DC supply with proportional 0-5V DC output
  • Alternative outputs available
  • Small size tube and clean lines allow easy cleaning
  • Most materials do not adhere to FEP, ensuring accurate measurements
  • Embedded temperature measurement option available
