The General Monitors IR5500 is an open-path IR gas detector that continuously monitors hydrocarbon gas concentrations. The system consists of an IR source and receiver that continuously monitor light hydrocarbons in the 0 to 5000 ppm and 0 to 5 LEL meter ranges.
A meter with a 0 to 2000 ppm range and a 0 to 1 LEL range is also available for monitoring heavy hydrocarbons. The IR5500 provides two 4-20 mA analogue signals proportional to the above ranges, a digital display, and relay contacts.
The IR5500 is easily aligned using the digital display and adjustable mounting arms. Therefore, it does not require bulky setup equipment (e.g., digital voltmeters, handheld alignment aids).
The IR5500’s sensitivity can be checked by placing a test gas film in front of the receiver.
The IR5500 is factory-calibrated and does not require any additional calibration. It also requires minimal maintenance, aside from periodic visual inspections, a test gas film check, and window cleaning, to ensure dependable performance.
Sensor data and status information from the IR5500 can be transmitted up to 9,000 feet (2,743 m) to any industrial analogue-to-digital (A/D) converter for multipoint computer-based monitoring.
IR5500 receiver part number 329000. IR5500 transmitter (source) part number 329001.
Features
- Dual detection ranges are sensitive to both small (ppm•meter) and large (LEL•meter) gas leaks.
- Performance approved for use in harsh environments.
- Single detection beam improves accuracy and reduces drift.
- Continuous self-check provides a fail-safe operation.
- Multiple communication outputs provide complete status and control capability in the control room.
- Unitised display allows ease of operation.
