Excel is a hazardous area certified flammable infrared open path gas detector. Open path infrared gas detectors are ideal for applications in the harshest environments where reliability and performance are of upmost importance. Excel provides the widest area of coverage, very high speed of response and no unseen failure modes.

Excel comprises of a Transmitter and Receiver that are mounted at each end of the path to be monitored. Three versions are available: Short Range (5-40m), Medium Range (40-120m) and Long Range (120-200m). Hazardous area approvals include European (ATEX), North Amercian (UL) and Canadian (CSA). Receiver output is 3 wire 4-20mA selectable sink or source.

Please note that Searchline Excel CSA covers on Methane-calibrate versions.

The DX termination unit (UL only) provides convenient mounting and field wiring connections as well as an intrinsically safe connection socket for the Handheld Interrogator. Additionally, the DX termination unit (UL only) allows for a multi drop Modbus RS485 interface. The Handheld Interrogator is a commissioning / maintenance tool and is certified for use in hazardous areas. For the direct connection to the Excel system, the SHC protection device module must be used.
