Propane gas sensor SBH

NDIRfor leak detectionminiature

The miniature NDIR C3H8 sensor SBH detects 0-75% of the propane (C3H8) concentration based on NDIR technology, which is superior to thermal catalysis and heat conduction technology. It has the advantages of convenient operation, accurate measurement, reliable operation, simultaneous output of voltage and serial port, and dual beam design. To meet the different requirements of industrial field and laboratory measurement, it is widely used in gas detection and analysis in petrochemical, chemical, coal, medical, laboratory and other fields. Features NDIR technology, with long life and full measurement range Meet the explosion-proof grade Ex iaⅡC T4 Ga Internal full range temperature compensation Diffusion sampling, stable performance High precision, high resolution 0.01% Small size and fast response Antiseptic Easy to install and reduce maintenance Compatible with digital and analog voltage signal output Specifications Measurement range 0-2%vol, 0-75%vol Measurement method NDIR Signal output UART_TTL; Analogue output: 0.4V-2VDC Warmup time: 30s Response time T90 ＜15s Working voltage 3.5-5.5v Working current 75-80mA Ex-proof Level ExiaⅡCT4 Ex-proof No. GYB14.1127 Digital signal format RS 232data bit: 8; stop bit: 1; check bit: null Baudrate 9600 bps Working temperature -40℃ to 85℃ Dimensions ￠20*19mm (except pin) Output pin 5pins Lifespan 8-10years
