Overview
Enviro Test Construct wall-mounted ammonia gas detector can also have a field detection concentration display, signal transmission, led lights and relay alarm function. Volkswagen series shows the fixed ammonia detector works is the site of the detection of ammonia gas concentration, converted to the corresponding standard signals (such as voltage signals (such as 0 V to 5 V or 10 V), current signals (such as 4 mA to 20 mA) , Standard digital signals (such as bus RS-485, RS232), frequency signal, Hart protocol signal, and then send the signal to the PLC, DCS, alarm control host and other host computer for unified display, management and control. Gas detector with a relay inside (switch signal), you can control the fan, sound and light alarm, solenoid valve and other equipment.
