1 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.
Supplied with worldwide performance (CSA / ATEX) 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 HS have no effect on the detector or the 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.
