GD10P IR Point Gas Detector
Brand: Detcon Inc
The Simtronics GD10P detector is the benchmark for combustible gas detection on offshore installations.
It has set the standard for gas detectors in the areas of safety, stability and low maintenance.
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 utilize silicon based solid-state infrared sources.
The complete optomechanical design and constructions 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.
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 and hazardous area approvals. Suitable for use in SIL 2 systems.
An industry standard HART interface is used for configuration of the optional fast response time and special fault levels as well as access to extended maintenance data.
