Application
The gas transmitter ADOS GTR 210 is suitable for continuous measurement of gases in normal areas and areas where there are risks of explosion.
Available basic versions:
– Ex-version: with current interface 4-20 mA
– Standard: 4-20 mA or LON®-4-wire techniques
– Comfort: 4-20 mA, with additional changeover
contacts for alarms and failure
By employing 6 different types of sensor, noxious, explosive and non-combustible gases and vapours can be measured.
Display of the measured gas concentration and the adjustable alarm thresholds, are shown on a multi-colour graphic display. The keyboard input is by way of a touchpad.
A current signal is generated that is proportional to the measured concentration of gas, which is transmitted to an evaluation unit placed in a safe area, away from any dangers of explosion.
The type test of the explosion-protected gas transmitter, is completed by the DEKRA.
