PDP Sensor ZHM100 TT-Eex

Pressure Dew Point of Gas
… is possible to measure by sensor ZHM100 TT-Eex

This sensor measures Pressure Dew Point (PDP) already at small flow of explosive gas. Ceramic sensor ZHM100 TT-Eex, detects partial pressure of water vapour which corresponds to PDP directly.

Complete measuring set consists of:

  • Moisture ceramic sensor ZHM100 TT-Eex
  • Sensor chamber
  • Display unit, incl. analog signal output card and output relay card
  • Power supply adapter
  • Shunt-Diode safety barrier
  • Blue cable for secure electric circuits
  • Cable connectoner


  • PDP range: +20 … -100°C, +/- 2°C
  • output 4-20 mA or 0-20mA
  • the range of calibration: PDP +20 … -75°C
  • gas pressure: up to 350 bar g
  • ATEX version
  • Protection IP66, NEMA 4

Sensor ZHM100 TT-Eex is optional device to adsorption dryers of technical gases.
