TGas-1033系列的红外天然气发射器

1Brief introduction TGas-1033 Series Infrared Gas Transmitter with four-wire system adopts the principle of infrared absorption spectra to detect the content of a certain gas in environment; it can continuously measure the site gas concentration, and output the concentration signal through RS485 bus. It has high sensitivity and its detection of leakage can reach 1ppm; its response time is quick; the service life of sensor is long. It is extensively applied in petroleum, petrochemistry, chemical industry, gas, coal, metallurgy and electric power; safety detection in municipal administration, communication and traffic tunnel construction; electronics, semiconductor industry and other places with poisonous and harmful gases. Main features Adopt principle of infrared absorption spectra to detect content of a certain gas in environmentIt has high sensitivity, and its detection of leakage can reach 1ppmThe precision is high and stability is good.The response time is quickService life of sensor is longTechnical parameters Measured gases SF6, CH4, C2H6, C3H8, C4H10, C2H2, C2H4, CO, CO2 Sampling mode dispersive Measurement principle infrared (NDIR) Range refer to table of lectotype Response time 1 5 second (s) Accuracy1.5%F.S Display of measured valueliquid crystal display by segment coding Output signal RS485 bus Output mode four-wire system Working temperature -20°C 50°C Working humidity <95%RH Power supply 24V power source Dimension 160mm×100mm×70mm Weight <950g Lectotype table for detected gas (part gas) ModelCategory of measured gasMeasurement range (volume content)Measurement precision TGas-1033-CO2-1CO2 gas0-5000ppm±1%F.STGas-1033-CO2-2CO2 gas0-2%±1%F.STGas-1033-CO2-3CO2 gas0-20%±1%F.STGas-1033-CO2-4CO2 gas0-100%±1%F.STGas-1033-CO-1CO gas0-20000ppm±2%F.STGas-1033-CO-2CO gas0-10%±1%F.STGas-1033-SF6SF6 gas0-1000ppm±1%F.STGas-1033-CH4CH4 gas (methane)0-4.4%(0-100%LEL)±1%F.STGas-1033-CH4-2CH4 gas (methane)0-100%±1%F.STGas-1033-C2H6C2H6 gas (ethane)0-2.4 %(0-100%LEL)±1%F.STGas-1033-C3H8C3H8 gas (propane)0-1.7%(0-100%LEL)±1%F.STGas-1033- C4H10C4H10 gas (butane)0-1.4%(0-100%LEL)±1%F.STGas-1033- C2H2C2H2 gas (acetylene)0-2.3%(0-100%LEL)±1%F.STGas-1033- C2H4C2H4 gas (ethylene)0-2.4%(0-100%LEL)±2%F.S
