Find answers to common questions about gas leak detectors, industrial gas detection systems, sensors, calibration, and certifications.
A gas leak detector is a device used to detect the presence of combustible, toxic, or oxygen-related gases in the air. Industrial gas detectors continuously monitor the atmosphere and can provide an alarm or signal to a gas detection control panel when the gas concentration reaches a preset level.
A gas leak detector uses a sensor designed for a specific gas or group of gases. When the target gas reaches the sensor, the sensor produces a signal proportional to the gas concentration. The detector can then transmit this signal through outputs such as 4–20 mA, RS485/Modbus, or relay contacts.
Industrial gas leak detectors continuously monitor areas where hazardous gases may be released. Depending on the gas, detectors may use catalytic bead, semiconductor, electrochemical, NDIR, or other sensing technologies. The detector can activate alarms and communicate with control panels, PLCs, BMS systems, valves, or ventilation systems.
