Through-beam gas alarm

The through-beam gas detector emits an infrared beam from the transmitter, and the receiver detects changes in light intensity after gas absorption. When gas concentration exceeds the standard, beam attenuation triggers an alarm. It is used in open areas such as chemical plants and oil depots to monitor leaks of flammable or toxic gases.
Selection
When selecting, confirm that the detected gas type and range match the on-site requirements. Consider the detection distance to cover the monitoring area, and ensure the environmental temperature and humidity meet the installation conditions. Check that the explosion-proof rating is suitable for hazardous areas, and that the signal output method is compatible with the existing control system. Regular calibration and maintenance ensure long-term stable operation.
