The Model HC800 is a line-of-sight infrared gas detection system that provides continuous monitoring of combustible hydrocarbon
gas concentrations in the range of 0 to 5 LFL-meters, over a distance of 5 to 120 meters. Standard system outputs include an electrically isolated/non-isolated 4-20 mA dc current output, with HART communication and RS-485 MODBUS communication. Alarm and fault relays are available as an option.
The system consists of two stainless steel modules — a transmitter and a receiver, along with mounting fixture hardware. Both modules are powered from an external 24 volt DC supply. The receiver provides the measurement signal outputs, and is furnished with onboard “status indication” LEDs and an internal magnetic calibration switch. The transmitter houses a high quality xenon flash lamp.
The HC800 is certified explosion-proof for use in Class I, Division 1 and Division 2 hazardous areas, and holds third party performance certification for methane gas detection. Propane and butane detection are also available (Det-Tronics verified). It can be used as a stand-alone detector, or as part of AutroSafe Integrated Fire and Gas detection system.
By connecting the transmitter and receiver via a three-wire shielded cable, an optional “communication link” can be created between the
two devices to enable: single point system diagnostics, dynamic lamp power optimization, synchronized LEDs, transmitter configuration via connection to the receiver, and calibration initiation from either device.
