The General Monitors IR5500 is an open-path IR gas detector continuously monitors hydrocarbon gas concentrations. The system consists of an IR source and receiver continuously monitoring light hydrocarbons in the 0 to 5000 ppm meter and 0 to 5 LEL meter range.
A 0 to 2000 ppm meter and 0 to 1 LEL meter range is also available for monitoring heavy hydrocarbons. The IR5500 provides two 4 to 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 volt meters, handheld alignment aids).
The IR5500’s sensitivity can be checked by placing a test gas film in front of the receiver.
The IR5500 is calibrated at the factory and needs no further calibration. It also requires little maintenance, other than a periodic visual inspection, test gas film check, and window cleaning to assure 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.
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.
- Automatic gain control compensates for dirty optics, rain, and fog.
