General Monitors announced a line of fixed hydrocarbon gas and flame detectors for operators at remote LNG production sites. The company’s detectors use catalytic bead, infrared point and ultraviolet/infrared technologies are intended for operators using portable vaporizers and temporary LNG sources.

The S4000CH Combustible Gas Detector provides continuous monitoring of combustible gases via its robust catalytic bead technology. The unit features calibration intended for use by one person by activating a magnetic switch and applying gas. It is designed to monitor natural gas and vapors within the lower explosive limit and provide status indication and alarm outputs. It complies with ANSI/ISA 12.13.01-2000 performance requirements for combustible gas detectors.

The IR400 Point IR Gas Detector uses infrared technology to sense for combustible gases and vapors to quickly and reliably detect LNG gas leaks. The detector is factory pre-calibrated, has a three-second response time, takes minutes to set up, operates with less than 4.8 Watts of power and is inexpensive to operate and maintain.

The FL3100H UV/IR Flame Detector monitors for both ultraviolet and infrared (UV and IR) spectral ranges and avoids false alarms caused by radiation sources. Continuous Optical Path Monitoring checks optical path integrity and electronic circuitry once per minute; a wide field of view enables greater fire detection coverage. The flame detector's electronics are integral within its explosion-proof housing, allowing detector information to be processed at the point of detection.
