Transmitter EX-proof | Temperature/humidity

Supplementary description:

The humidity/temperature transmitter has been designed specifically for measurement in explosion hazard areas. It complies with the classifications for Europe (ATEX), International (IECEx) and USA / Canada (FM). Accurate measurement over the full range of 0…100 % RH and -40…180 °C (-40...356 °F) is also possible in applications under pressure from 0.01 … 300 bar (4351 psi).

Special features:

  • Approved for gas and dust
  • Installation in zone 0 / Div. 1
  • Calculation of related physical quantities
  • Stainless steel housing and probe
  • Highest accuracy up to 180 °C (356 °F)
  • Pressure tight up to 300 bar (4351 psi)
