3.1 GENERAL DESCRIPTION
The AMC-360-IREP sensor/transmitter unit is designed to provide continuous, reliable
surveillance of surrounding air for up to 100% by LEL methane. Used with this sensor, the unit
provides a 4 to 20 mA, variable current signal which is proportional to the gas concentration
currently detected. Each sensor/transmitter unit is factory calibrated with its interconnected
sensor and is ready for field installation and operation.
