There are multiple tasks which need to be fulfilled when monitoring gases and vapours. TheThere are multiple tasks which need to be fulfilled when monitoring gases and vapours. Therange covers the opportune warning before it comes to the release of flammable substances,monitoring of concentrations of toxic gases at working places as well as controlling of productionprocesses. Due to modern sensor technique the ExTox-Transmitter of the Serie ExSens(-I) offer excellent solutions for nearly all thinkable applications.
You find our wide range of measuring gas and corresponding measuring ranges in the Gas and Transmitter List.

▪ Application in explosion hazardous areas of Zone 2
Features
Measured Gas: Type designation, e. g. R1234yf for transmitter Ex2Sens R1234yf-5000-IR, or Gas and Transmitter List
Measured Gas: Type designation, e. g. 0 to 5000 ppm for transmitter Ex2Sens R1234yf-5000-IR, or Gas and Transmitter List

(Subject to Technical Changes)
All control units of the ET-Series could be used in combination with all ExTox Transmitters Ex2Sens.
Due to their modular construction accessories and spareparts are mutually extensively interchangeable, which facilitates and enables installation, adjustmentand maintenance at low cost. The transmitter disposes of a current output 4…20 mA, which serves for transfer of measured values and/or messages of special states to an ExTox-Control Unit or any other suitable control system..
