1.2 GD10PE Description
The GD10PE is designed for critical applications involving large volumes of air with high velocity.
Places where you need fast reliable detection of low gas concentrations. GD10PE is in a class of
its own.
These infrared gas detectors differ from all other models, because they utilise silicon based solid-
state infrared sources. The complete opto mechanical design and construction is so stable that an
ultra-fast speed of response can be achieved whilst providing unparalleled service life and
detector stability, thus saving on maintenance and service costs.
We offer the longest combined detector and IR source warranty on the market.
Typical critical applications include the monitoring of air intakes for HVAC systems in living
quarters or generators, and monitoring for potential gas leakages in areas with high temperatures
in gas turbine packages.
The GD10PE is a stable instrument, and with a measuring range of 0 – 20%LEL the sensitivity for
the GD10PE is 5 times higher than standard point detectors.
The GD10PE is designed for installation in air ducts and for mounting through walls and
bulkheads in places such as pump rooms, but may also be used as a standalone point detector
in places where the properties of the GD10PE is required, such as low ppm level detection.
A weather protection accessory is used for exposed detector installations.
•
Duct mounted close to the intake.
•
Directly mounted on an air intake.
•
General outdoor locations.
The detection concept is based on the measurement of infrared radiation passing through a
volume of gas.
Solid state IR-source
The silicon-based IR-source used in the GD10PE is insensitive to shock and vibration, and does
not need to be replaced during the detector service life.
No false gas alarms
A false alarm, resulting in a production shutdown is extremely expensive. The dual wavelength,
dual path concept, together with the electronic design, guarantees that there are no false gas
alarms.
No field recalibration
Field recalibration of gas detectors is time consuming (cost) and introduces a risk of mistakes
(safety). The GD10PE stays within the specifications for its service lifetime without recalibration.
The response time is among the fastest on the market, giving real world figures. We measure the
response from the actual gas release, taking delays of the weather protection, initial detection,
etc. into account. Trip levels down to 4%LEL combined with a response time in the range of 1
second (option) should cover even the most demanding requirements.
