PRODUCT DESCRIPTION

The GD10P has been designed with features that provide an effective response to
the detection of gas hazards in a wide range of industrial environments from boiler
plant rooms to offshore petrochemical installations.
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.
For retrofit applications, a bridge interface is available allowing the detector to be
connected directly to catalytic systems, using the existing cabling and control
modules.
Supplied with worldwide performance (CSA / CENELEC) and hazardous area
approvals.
Suitable for use in SIL 2 and SIL 3 systems.
Compared with catalytic sensors, the GD10P has the following advantages:

Presence of oxygen is not required for correct measurement, which makes the
GD10P suitable even in an inert gas atmosphere.

No possibility of poisoning of the detector since no chemical reaction occurs,
i.e. silicon vapours and H
measurement.

The gas flow rate has no influence on accuracy.

There are no saturation effects which could lead to false measurements. Thus,
the detector is capable of measuring gas concentrations up to 100% vol.

The detector has a continuous self-test function, and reports dirty optics and
fault conditions to the control system.

Total system costs can be dramatically reduced with the GD10P:

High reliability results in low test frequency and no calibration costs.
