SELECTING GAS SENSOR TYPES
Hansen Gas Sensors are available in several types of
enclosures to match the environmental and operating
conditions.
PORTABLE GAS DETECTION UNIT
Por table Gas Detection unit includes
the handheld unit, batter y charger,
extension wand, spare filters, voltage
output cable, accessories for calibration,
and sensor module keeper for four
sensors in a carr ying case. Sensor
modules sold separately. Por table
Unit, p/n 31-1010.
GAS SENSOR ACCESSORIES
Sensor Element Shield
The Sensor Element Shield can be screwed on to the
end of the gas sensor to help protect the sensor from
rain, dust, hose directed water, and debris floating in the
air. It can be installed on the Standard, Harsh, Extreme
and Explosion Proof gas sensors. The shield may slow
response time slightly depending on the surrounding
air flow conditions. Shield, p/n 31-1002.
Standard Gas Sensor
For operating temperatures down to
0ºF (-17ºC). NEMA4 (IP65) water tight

material; conduit connection must be
vaporproof.
Extreme Environment Gas Sensor
For operating temperatures down to
-60ºF (-51ºC). Features a stainless steel
metal enclosure and equipped with an
integral heater and thermostat for low
temperature operation. Enclosure is
NEMA4X (IP65); conduit connection
must be vaporproof.
Note: Auxilliar y power required when
used with Hansen monitors HLM2 and
HLM6 and Gas Aler t System.
Vent Line Gas Sensor
For operating temperatures down to
-40ºF (-40ºC). Enclosure is NEMA4 (IP65)
ABS material. Gas sensing element is
in a separate carbon steel housing with
an 1˝ NPT threaded connection; cable
is 10 feet (3 meters).
Explosion Proof Gas Sensor
For operating temperatures down to
- 40ºF (- 40ºC). Enclosure is NEMA7
Aluminum. Used where regulations
and codes specify; consult factory with
specific requirements. Class I, Div II,
Group C and D.
Basic Gas Sensor
For operating temperatures down to 0ºF
(-17ºC). For commercial applications
s u c h a s s u p e r m a r ket r e f r i g e r a t i o n
systems and air conditioning chillers.
Enclosure is NEMA1 (IP41) for indoor
installations; enclosure is ABS material.
Low voltage cable wiring only. (Not
available for Ammonia).
QUICK DISCONNECT
PLUG KIT
Quick Disconnect Plug Kit
The Quick Disconnect Plug Kit can be added to the gas
sensor to provide a means of easily removing the gas
sensor for recalibration. This feature comes in handy
for gas sensors installed in blast cells, low temperature
rooms and hard-to-reach places. The gas sensor
cable can be quickly disconnected and the entire gas
sensor removed or replaced with a bench recalibrated
gas sensor. The gas sensor can then be brought to an
alternate location for recalibration or sensing element
replacement. Quick Disconnect Plug Kit, p/n 31-1001.
Option only available for field installation. Supplied
cable is 2 feet (0.6 meters) in length.
