EX-5175 Electrochemical H2, O2, H2S & Other Toxic Gases Sensor

Explosion-proof Remote Gas Monitoring Sensor Transmitter for H2, O2, CO, H2S and Other Toxic Gases

EX-5175 remote gas monitoring sensor transmitter utilize electrochemical type cells to detect the target gas. These cells consist of electrodes, electrolyte and an air/liquid separation barrier. Gas molecules enter the cell and, as a result of an oxidation/reduction reaction, generate an electrical current proportional to the gas concentration. This current is measured, conditioned, converted to the gas concentration, digitally displayed and transmitted as a 4-20 mA output signal. The Ex-5175 sensor transmitter operates on 24 VDC power and features three LED alarm point indicators and 4-20 mA output. This sensor transmitter can be connected to various single and multi-channel ENMET controllers or computer-based instrumentation, such as PLCs, SCADAs, BMSs, etc.
