Infrared gas sensor module
The NE-101 series high-precision infrared gas sensor developed and produced by Shengjian Technology is a gas sensor module using NDR infrared absorption detection principle. The sensor adopts imported light source, optical cavity with special structure and dual-channel detector to realize spatial dual-optical path reference compensation, and the microprocessor to collect, process and output the signal. The linear error is better than 1% of the full-scale taxi, the zero drift is small, and has good selectivity, high sensitivity, no oxygen dependence, long life and low power consumption. Built-in temperature sensor for temperature compensation; Also has 4-20mA/0.4-2V, UART, Modbus(user optional) output; The alarm point can be set and can be easily and quickly connected to the existing monitoring and control system for the convenience of customers for various applications.
