Combustible Gas Detector Provides 3-Second Response to Dangerous Leaks

generalmonitors0228.jpg

The model IR400 Point IR combustible gas detector from General Monitors features a three-second T90 response time to the presence of combustible hydrocarbon-based gases. This design helps plant operators quickly respond to gas leaks and avoid potential accidents.

The gas detector includes rapid fail-to-safe continuous gas/vapor monitoring within the lower explosive limit (LEL). It alerts plant employees to gas leaks and warns them to shut down processes in affected areas.

The gas detector responds within three seconds to gas leaks even with a splash guard installed to protect it from rain and other environmental conditions. The gas detector monitors hydrocarbon-based gases including methane, propane, ethane, ethylene, butane, hexane, pentane and benzene. It features a self-diagnostic design to prevent false alarms and process shutdowns. It monitors conditions such as supply voltage and optical path integrity. The IR400 also features heated optics to eliminate condensation and a dirty optics indicator helps discriminate between true alarms and maintenance needs. 

The model uses 4.8 watts of power. The detector requires no routine calibration, a feature that may reduce field technician maintenance time.  The IR400 operates by measuring the absorption of infrared radiation passing through a volume of gas using a dual beam, single detector method. The IR detector measures the intensity of two specific wavelengths, one at an absorption wavelength and another outside of the absorption wavelength. The gas concentration is determined by comparing these two intensities.
