Sierra Monitor Corp.: CO Gas Sensor Module
June 20, 2011
The 4501-04 two-wire carbon monoxide gas sensor module has 4-20 mA two-wire, loop-powered gas detectors. This eliminates the need for separate power runs and associated power distribution and circuit protection for each device. The user-friendly operator interface with integral scrolling menu-driven LCD display permits easy access to gas status, calibration instructions, adjustment of ranges and outputs, and diagnostic information. It has the durability of a stainless steel transmitter and sensor enclosure. Nonintrusive calibration enables calibration without declassifying the area. It offers application adaptability with variable range selection and mounting configuration. According to the manufacturer, the gas sensor module has low maintenance costs due to a 180-day (six-month) calibration interval.
