Modular Gas Detector .......

Self Checking Gas Sensors
GasSens is a flexible component system providing a
variety of options to meet individual gas detection and
alarm requirements. From chemical and petrochemical
plants to food processors, the GasSens system can be
applied to the simplest or most complex gas detection
application. Economical and low maintenance, this
system is your best choice for reliable leak detection.
GasSens detection systems consist of individual
modules that can be located where required.
Sensor/transmitters, located in the area where gas
leakage or buildup might occur, provide the basic
measurement for the system. Sensor transmitters are

Gas & Range Availability

available in either NEMA 4X or explosion-proof versions
and can be supplied with ATI’s exclusive Auto-Test
automatic sensor testing system, greatly reducing
operator testing requirements.
Receiver modules provide the electronic brains for
the detection and alarm system. Each compact module
includes a digital display of gas concentration, isolated
analog output, and 4 relay outputs. Receivers may be
located up to 1000 feet from sensor/transmitters for
remote indication, or can provide local control functions
such as valve shutoff while transmitting a 4-20 mA signal
to remote displays or data loggers.
Universal power supply modules provide DC power
to receivers. The power supply is housed in a compact
module similar to the receiver, and will accept inputs
from 85 to 265 volts, AC or DC, without adjustment. The
power supply also provides a power failure relay and
charging for an optional battery back-up unit.

Applications include: Chemical plants; pulp & paper
mills; semiconductor fabrication; food processing;
water treatment; mineral processing; wastewater
treatment; parking facilities; gas processing; and
petroleum refining.
