SEC 3000 Gas Detector
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 explosion proof transmitter or the SEC 3100 DIN Controller.
The SEC 3100 has a backlit LCD display,
non-intrusive local calibration, 4-20 mA output, non-intrusive local configuration,
optional relays, RS-485 interface and
intrinsic barrier.
