Standard Gas Sensor
INTRODUCTION
Hansen Technologies offers a complete line of industrial
quality Gas Detection Sensors, Monitors and Alert
Systems for refrigerants and other common gases. These
state-of-the-art gas detection products utilize a range of
sensing technologies to suit a given application. Available
in several configurations to meet various application
requirements with optimum accuracy and reliability.
APPLICATIONS
Hansen Gas Sensors are suitable for use in industrial
refrigeration engine rooms, cold storage rooms,
processing rooms, truck docks, and for relief valve vent
lines. They are also suitable for use in supermarkets,
and large institutional and commercial buildings.
Typical gas detection applications include Ammonia,
Carbon Dioxide (CO
2
), Hydrocarbons, HFCs, HCFCs
and CFCs.
ADVANTAGES
Hansen uses a wide variety of sensing technologies
including electrochemical, semiconductor and infrared
sensors to selectively detect most gases. These sensors
continuously determine the level of gas present in the
surrounding environment. The analog outputs (4-20mA
or 0-10V DC) can interface with nearly any existing
monitor, computer or PLC controller.
The sensing elements (except Basic and Extreme Gas
Sensors) are mounted externally on the enclosure. This
helps to provide quick response to potential leaks,
particularly in still air. Electronics are sealed in a NEMA4
enclosure (except Basic Gas Sensor) which protects
them from moisture, dust and the surrounding gases,
which in the case of ammonia can shorten the life of
electronics. The sensing elements are easily replaced.
Gas Sensors have built-in visual and audible alarms. An
auxiliary one amp SPDT relay output is standard. Testing
and recalibration procedures are simple.
