1.0 Introduction
The SE-5175 sensor/transmitter (S/T) instrument is a 3 wire, 24 VDC, 4-20mA S/T, that measures and detects various types of
toxic gases utilizing an electrochemical sensor. The SE-5175 is NOT in an enclosure rated for use in a Class I, Div 1, Groups
B, C, D classified area and C
Features of the SE-5175:
continuous monitoring of the sample air
continuous LCD display of gas and vapor concentrations
menu driven operational and maintenance controls
menu driven calibration procedure
mA outputs for target gas
Sensor/Transmitter are three wire device, with two of the wires forming a 4-20mA loop
