1 Product description
Compared with catalytic sensors, the GD10P and GD10PE has the following advantages:
•
Presence of oxygen is not required for correct measurement, which makes the GD10P/PE
suitable even in an inert gas atmosphere.
•
No possibility of poisoning of the detector since no chemical reaction occurs, i.e. silicon
vapors and H
2
S 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/PE:
•
High reliability results in low test frequency and no calibration costs.
GD10P and GD10PE are sensitive to absorption bands related to carbon - hydrogen bonds.
As a result, all molecules with this type of bond are susceptible to detection. The intensity of this
absorption line is, however, significantly dependent on the molecule under consideration.
In general, the larger the molecule is, the greater the absorption strength will be, and so the better
it is detected.
There is therefore some measurement interference between hydrocarbon vapor compounds since
their absorption bands share some spectral regions.
The level of interference depends on the relative position of these absorption bands, relative to
the working range of the interference filter.
1.1 GD10P 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 use 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 / IECEx / ATEX / INMETRO) and hazardous area
approvals.
