Product Description
Fixed toxic gas detection system with ATEX certificate QB2000N is a fixed gas detecting transmitter, with 4-20 mA or RS485 ModBus RTU output proportional to the gas leakage concentration with original imported catalytic combustion or electrochemical sensor. It monitors gas leakage by natural diffusion.
fixed toxic and harmful gas monitoring detection system with 4-20mA or RS485 output 0
Features:
♦4-20mA analog output for direct communication to DCS system ♦Relay output for connecting external device ♦LCD display screen(LED display screen optional) ♦Advantage: Sensor module(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously. ♦Password verification for repeat operation, avoid fault operations. ♦-40～+70℃ following compensation for accurate detecting. ♦Twp grade visual alarms on-site and Relay (connected with audible/visual alarms or drive exhaust device). ♦User-selectable alarm setpoint(s).
