Gas detector LGD-R

tunable diode laserremotewavelength

The Remote 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 Advantages 1 Long Detection Distance and Wide Detection Range LGD-R’s detect distance can reach up to 30 meters and detect range can reach up to 40000ppm·m. 2 Widely Applied LGD-R has a flameproof design, and it can be used in Zone 1 and Zone 2. Its IP class is IP65; it is suitable for petroleum, petrochemical, and electrical industries. 3 High performance-price Ratio LGD-R scan continuously in all types of conditions. It does not need to be replaced or checked regularly. Its life span can be up to 5 years. 4 Universal Communication Protocol LGD-R uses Modbus RS-485 communication protocol, which uses a combination of balanced driver and differential receiver, and has the capability of resisting common mode interference and noise interference. Its communication distance can reach more than 1 km, while connecting to a variety of integrated systems.
