Teledyne Oldham Simtronics GD10P Infrared Point Gas Detector
The Teledyne Oldham Simtronics GD10P Infrared Point Gas Detector (formally known as SIMRAD 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.
The GD10P infrared gas detectors differ from all other models because they utilise silicon-based solid-state infrared sources. The complete optomechanical design and construction are so stable that an ultra-fast speed of response can be achieved while providing unparalleled service life and detector stability, thus saving on maintenance and service costs.
Teledyne offers 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. The unit is supplied with worldwide performance and hazardous area approvals. Suitable for use in SIL 2 & SIL 3 systems. An industry standard HART® interface is used for the configuration of the optical fast response time and special fault levels as well as access to extended maintenance data.
