Hengesbach is a company from Deutschland. For more than 50 years Hengesbach develops, manufactures and distributes innovative measuring technology for applications in production processes where functionality, reliability and accuracy of the instruments are of highest priority even under extreme process conditions.

Depth-Measuring Sensor Type TPS-T

Typical applications of the piezo-resistive depth-measuring sensor of the type TPS-T are the continuous measuring of filling levels in wells, drill-holes, waste-water systems, standing water bodies and containers that cannot be fitted with a measuring transducer that is flush with the wall of the container. The 4-20mA output signal is proportional to the filling level or pressure and is also available with a 4-wire temperature output.

Features:

  • for hydro static filling level and depth measurements in wells, drill-holes, containers, waste-water systems, etc.
  • pressure ranges from 0 … 0.25 bar to 0 … 25 bar
  • output signal 4…20 mA
  • compact and robust construction
  • optionally with temperature output
