EX-5175 Explosionproof Sensor/Transmitter for Hydrogen, Oxygen, Carbon Monoxide, and Other Toxic Gases
Three Alarm LEDs
NEMA-4X, NEMA 7 and IP66 Rated Enclosure
24 VDC, 4-20 mA
Liquid Crystal Display
Non-Intrusive Calibration
Approved for Class I, Division 1, Groups B, C, & D
The EX-5175 Series Sensor/Transmitters 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, a reult of an oxidation/reduction reaction, generate an electrical current proportional tothe gas concentration. This current is measured, conditioned, converted to the gas concentration, digitally displayed and transmitted as a 4-20 mA output signal. ENMET offers variety of multi-channel controller/alarm modules that provide the 24 VDC loop power and receive the 4-20 mA signal from the sensor/transmiters. These sensor/transmitters can also be connected to various computer-based instrumentation, PLCs, etc.
