New IR Sensing Combustible Gas Detection System

The new IR4000 Infrared Combustible Gas Detection System from General Monitors (USA) is a scalable plant safety solution with voting. The system’s IR4000M Multi-Point Monitor can connect up to eight IR400 Point IR Gas Detectors and read their status with one command, one detector at a time. The IR4000M can also calibrate, gas check and zero each IR400 sensor with a single command, reducing the cycle time for routine maintenance.

The IR4000M is highly versatile. The monitor incorporates a display, relay module and a data concentrator in an explosion-proof enclosure and magnetic interface, which permits installation and calibration in hazardous locations.  Optional 8-Amp relays expand system functions, reducing the need for integration with other controllers.  HART and Modbus permit the device to convey device IDs, concentration readings, and time-stamped diagnostic, maintenance, and warning and alarm records to the control room.

The versatile IR4000 System is suitable for a wide range of hazardous industry processes and plant applications:  LNG/LPG processing and storage, electric power generation plants, oil and gas production platforms, petrochemical refining, compressor stations, aerospace facilities and wastewater treatment.  The system is certified by FM, CSA, ATEX, CE Marking and IECEx for worldwide application and is also suitable for use in SIL 2 environments.
