Sheng Kaian -sf6 sensor -sf6-2000ppm-sf6 sensor

NIDR infrared gas SF6 / sf6 body sensor module Shengkai An R & D, production of NE-101 series is a high-precision infrared gas sensor using infrared absorption detection principle NDIR gas sensor modules. The sensor uses imported light source, optical cavity structure and a special dual-channel detectors, spatial reference double optical path compensation, the microprocessor signal acquisition, processing and output, linearity error is better than full scale ± 1%, zero drift, has good selectivity, high sensitivity, no oxygen dependence, long life, low power consumption; built-in temperature sensor for temperature compensation can be; both 4-20mA / 0.4-2V, UART, Modbus (user optional) output;??? Alarm can be set up, it can be easily and quickly connected to existing monitoring and control system to facilitate the structure and characteristics of client products for various applications of infrared measurement principle NDIR single light source, dual beam digital signal processing ? automatic temperature compensation? 4-20mA / 0.4-2V, UART, Modbus variety of signal output options? imported components, stable performance, low volatility? long life, automatic zero calibration? multi-point calibration, measuring range good linearity ?
