3.1 GENERAL DESCRIPTION

The AMC-350 series sensor/transmitter unit is designed to provide continuous, reliable
surveillance of surrounding air for traces of hazardous gases (listed in Factory Calibration,
section 2.2). It provides a 4 to 20 mA, variable current signal, which is proportional to the gas
concentration detected. Each sensor/transmitter unit is factory calibrated and ready for field
installation and operation.
