Submersible Pressure Transducers

Submersible pressure transducers are for underwater use. They are sometimes called Borehole transducers or tank level sensors. Submersible pressure transducers are an excellent solution for monitoring level for either indoor or outdoor applications. They provide accurate measurement within these harsh environments.

Submersible pressure transducers are used to measure liquid level. The transducer is often located at the bottom of a tank, the pressure applied to the transducer will be directly proportional to the amount of liquid, as the tank empties/fills the pressure becomes lower/higher and this is measured by the transducer. 

What are Submersible Pressure Transducers used for?

Submersible pressure transducers can be used for any underwater liquid level detection, they are cost-effective and are compatible with many different types of liquids including water, Leachate, fuel and other chemicals. Some typical applications for submersible pressure transducers are;

  • Ground Water Level Measurement
  • Earthen & Concrete Dams
  • Irrigation systems 
  • Building Automation Controls
  • Waste Water Canals
  • Liquid Tanks
  • Environmental Sites

Benefits of Submersible Pressure Transducers

As well as being cost-effective and adaptable, submersible pressure transducers are well suited to their applications because they have the following benefits; 

  • High Strength Stainless Steel Construction
  • IP68 Protection
  • Rugged Design with No Internal O Rings
  • Compact Designs
  • Wide Operating Temperature Range
  • Pressure Ranges up to 100 PSI in some models and up to 25 bar in others. 
  • Low Static and Thermal Errors
  • New Conduit Fitting at Electrical Connection
  • Unparalleled Price and Performance
  • EMI/RFI Protection

Submersible Pressure Transducers from Variohm

We have a few submersible pressure transducers; Our own EPT-LM, the PS1 Series from ADZ and the AST45 series from our supplier TE Connectivity, they can all be found on our pressure transducer page.

EPT-LM - up to 25 bar

AST45PT - Combined pressure and temperature measurement 0-1 to 100 psi

AST4520 - 0-2 to 15 psi

PS1 - up to 25 bar
