ExSens - Model (-I) Series - Transmitter
From Gas Measuring Transmitter
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.
Product Details
All control units of the ET-Series could be used in combination with all ExTox Transmitters ExSens(-I) and Sens(-I). Due to their modular construction accessories and spareDue to their modular construction accessories and spareparts are mutually extensively interchangeable, which facilitates and enables installation, adjustmentand maintenance at low cost. The transmitters issue the measuring signal via a 4-20 mA-output with linear curve. The typesThe transmitters issue the measuring signal via a 4-20 mA-output with linear curve. The typesExSens-I and Sens-I also dispose of a digital RS-485 communication interface. This offers thepossibility of an automatic single man calibration of these transmitters as well as furthercomfortable functions for configuration and monitoring of the sensor functionality.
