Gas detector LGD-P

flammable gasmethanedigital

Laser Gas Detector is based on Tunable Diode Laser Absorption Spectroscopy (TDLAS). The detector emits a special wavelength laser to the gas and demodulates the laser signal passing through the gas. Combined with advanced microelectronic control technology, TDLAS can easily obtain the concentration of flammable gas (such as methane) in the gas. Advantages 1 Wide Application Can be used in methane gas detection, alarm occasions, gas extraction, transportation, and storage in gas related chemical, power generating, and heating areas. 2 Stable Performance The optical performance of laser is very stable, and the detected gas can easily be accurately identified. The special wavelength laser beam has unique selectivity to methane and other gases, while remaining free from the interference of other gas, water vapor, dust, and temperature changes. 3 No Maintenance LGD-P has no probe aging, regular replacement, verification cumbersome, or any other problems of traditional detectors; it will not be affected by gas concentration. 4 Long Life-span and Economical The Life span of LGD-P is more than 5 years. Although the one-time investment is more than traditional detectors, the total cost is much less in consideration of maintenance. 5 Standardized Design LGD-P is a 3-wire 4～20mA（HART optional）instrument signal output. It can completely replace traditional detectors. It has wider working voltage range. It also has alarm function and digital display screen to facilitate usage and management.
