High Resistance Sensors

High Resistance Level Sensors

The Paratronic company has designed a specific range of SNC submersible sensors for level measurement in aggressive media (chemicals, salt water).

Thanks to its design, digital electronics, Peek body, cable in fluorinated insulation, and ceramic flush diaphragm, this range of sensors is adapted to applications in the most severe environments.


Level measurement in aggressive media such as:

  • tanks or cisterns containing chemicals
  • salt water

Main benefits

  • Robust and resistant design
  • High metrological reliability
  • Guaranteed watertightness
  • Venting of the pressure sensor through the cable (double-skinned cable without capillary)
  • Parameterizable probes


  • Installation/Fixing: Suspended by the cable or screwed on pressure tap 1' 1/4 G
  • Materials:
    — Body made of PEEK (Polyetheretherketone/PolyEtherEtherKetone)
    — Ceramic membrane
    — PEEK stopper
    — Gaskets: EPDM, FPM or FFKM upon request
  • Cable:
    — Double skin, without capillary
    — Outer sheath in orange fluorinated insulation
    — Electrical shielding, 2 conductors 0.60 mm² (60mΩ/m cable)
    — Max. length 500m
  • Dimensions: diameter 44 mm, length 158 mm
  • Weight: 500g + 50g per meter of cable
  • Measuring ranges (configurable): 0 - 0.05 Bar to 0 -1 Bar
  • Overall accuracy from 0 to 40°C (includes linearity, hysteresis, repeatability and temperature drift): +/- 0.1% FS max (+/- 1mbar)
  • Long-term drift / constancy (at 25°C): +/- 2 mBar non-cumulative
  • Storage / use temperature: - 20°C to + 60°C / - 10°C to + 50°C in liquid phase
  • Power supply: 8V to 35VDC, limited to 1A
  • Output signal: 4-20 mA
