The Searchline Excel open path infrared gas detector is an innovative and relevant solution for the detection of hydrocarbons over long distances. It is a device able to replace several point detectors over an up to 200 meters distance between the transmitter and the receiver.
The Honeywell Searchline Excel system includes a transmitter that produces infrared radiation and a receiver with optical sensors that electronically processes the signals. They are both incorporated in a resistant stainless steel frame for use in the harshest applications and environments. Detailed description
The open path gas detector
The Searchline Excel open path infrared gas detector was designed to detect hydrocarbons in an industrial environment. It is a particularly economical solution that can replace up to 20 fixed point gas detectors over a 200 meters distance. It is completely insensitive to sunlight or other interference radiation sources such as flares, arc welding, or lighting.
The transmitter lens is heated to minimize condensation effects, freezing and snow accumulation. When it is very cold, SMART heating increases significantly.
Why an open path gas detection system?
- Extended surveillance zone: greater likelihood of leak detection
- Very fast response time (T90 <3 seconds)
- High sensitivity which allows earlier alarms with lower thresholds
- Less strategic location of detectors
- Simple installation and commissioning, a single system replaces several point devices
Searchline Excel open path gas detector main assets
- Solid state detectors with full temperature compensation
- Dual bandpass filters that compensate interferences from all types of fog, rain and mist
- Symmetrical heating elements integrated into the windows offering excellent performance at low temperatures
- Insensitive to solar radiation
- Examples of gas leaks not detected by conventional point detectors but identified by an open path gas detector:
- Offshore platforms and ships (storage and unloading)
- Chemical and petrochemical plants
- Gas and oil pipelines
