Introduction The Process Gas Laser Analysis System of LGA-4500(Extractive Model), the extractive process gas analysis based on the technology of diode absorption spectroscopy (DLAS),is able to make on-line analysis on carious process gases with high dust or high pressure after the extractive treatment and is with such features as strong adaptability and high reliability. Features 1.Laser extractive measurement, high measurement accuracy, strong anti-interference ability 2. Optical non-contact detection, with the ability to direct measure gas with high temperature and strong corrosion 3. Simple and reliable extractive treatment equipment, with the possibility to be directly installed at the process pipeline 4.While system explosion-proof, supporting the automatic compensation of gas temperature and pressure. 5. Corrosion Resisting High Temperature Type Extractive Pipeline Technical Parameters Linearity error: ≤±1%F.S. Span drift: ≤±1%F.S./half-year Repeatability: ≤±1%F.S. Explosion-proof grade: Expxdia llC T5 Protection grade: IP65 Response time Warm-up time: ≤15Min Response time: ≤5s (T90) Interface signals Analog output: 2-path 4-20mA, isolation, maximum load of 750 ohm Relay output: 3-path relays, 24V, 1A Digital communication: RS485 (RS232 or GPRS optional) Electrical characteristics Power supply: 100-240V AC/48-63Hz
