3PRODUCT DESCRIPTION
The AMC-VersaTox sensor/transmitter unit is designed to provide continuous, reliable
surveillance of surrounding air for the target gas listed in the Factory Settings (Section 2.2).
This unit is powered by either AC or DC power source and provides a 4-20 mA, variable current
signal, which is proportional to the gas concentration detected. Optional gas concentration
digital display is available as well as a built-in alarm relay contacts. An optional 120VAC plug in
power supply is also available with a relay controlled buzzer. Each sensor/transmitter unit is
factory calibrated, and is ready for field installation and operation.
Each sensor module features alarm indicators, adjustment trimmers and connection terminal
blocks, as listed and described below.
