Combustible gas detectors from General Monitors are helping oil and gas engineers accurately detect gas during the production of natural gas at drilling rigs.

Pockets of combustible gas potentially escaping from shale drilling rig production require fixed gas detection monitoring equipment to maintain a safe operating environment for people and equipment.

Oil and gas engineers responsible for hydraulic fracturing operations in natural gas production can use these combustible gas detectors from General Monitors to accurately sense potentially explosive hydrocarbon gas and alert crews in time to complete an orderly shutdown of the drilling rig.

Backed by decades of field proven experience and incorporating precision sensor technologies, General Monitors’ S4000CH and IR400 combustible gas detectors provide a highly reliable early warning alert to production workers.

Model S4000CH Intelligent gas detectors feature General Monitors’ robust catalytic bead sensor, which provides exceptional reliability for precise gas detection, ease of set-up and use, as well as simple maintenance. These gas detectors also deliver dependable safety monitoring with low cost-of-ownership in harsh industrial process environments.

Model IR400 Infrared (IR) point detector features a self-diagnostic design to prevent false alarms and process shutdowns. In addition to monitoring conditions such as supply voltage and optical path integrity, the IR400 features heated optics to eliminate condensation, and a dirty optics indicator to help discriminate between true alarms and maintenance needs. No routine calibration is required on this detector, reducing demand for field technician maintenance time.

Key features of the S4000CH and IR400 combustible gas detectors include microprocessor-based design; continuous monitoring of combustible gases and vapours within the lower explosive limit (LEL); all electronics contained within explosion-proof housings to allow information to be processed locally; 4-20mA signal, which is proportional to 0 to 100% LEL gas concentration at the detectors; one-person calibration, can virtually self-calibrate with simple activation of a magnetic switch and applying gas; and configurations with analogue output, Modbus and HART also available.
