Operation
The SEC 3000 gas detector is a unique design combining intrinsically safe and explosion proof
approved standards. This allows for quick and simple field installation of a calibrated sensor module into
the gas detector in hazardous locations with power applied.
The SEC 3000 sensor module retains operating parameters and calibration settings. Once the sensor
module is plugged into the gas detector, the sensor module automatically uploads current information to
the control board in the SEC 3000. Changing to a different type of gas sensor is accomplished by only
changing the sensor module board. The existing housing and wiring remains intact.
An industry standard 4-20 mA analog output provides remote alarm, fault and calibration signals. The
entire unit utilizes self-diagnostics, identifies problems and continuously transmits status.
The SEC 3000 can be used inconjunction with the SEC 3100 explosion proof transmitter. The SEC 3100
has a backlit LCD display, non-intrusive local calibration, 4-20 mA output, non-intrusive local configura-
tion, optional relays, RS485 interface and intrinsic barrier.
