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 in conjunction with the SEC 3100 or SEC 3120 explosion proof or DIN nonexplosion
proof transmitters. The SEC 3100 and SEC 3120 have a backlit LCD display, non-intrusive
local calibration, 4-20 mA output, non-intrusive local configuration, optional relays, RS485 interface and
intrinsic barrier.
