5% Measurement SF6 Gas Detector Sensor Module MEMS Light Source,Operating Humidity 0-90%RH
KSS530 Infrared SF6 Gas Sensor Module
1. Overview
KSS530 is a gas sensor module using NDIR infrared absorption detection principle, which determines the concentration according to the absorption of SF6 gas at 10.6um. KSS530 adopts MEMS light source, optical cavity with special structure and dual-channel detector to realize spatial dual-optical path reference compensation, and microprocessor for signal acquisition, processing and output. KSS530 has good selectivity, high sensitivity, no oxygen dependence, long life, low power consumption; Built-in temperature sensor for temperature compensation; At the same time, it has UART, 485 output and analog voltage output, which is convenient for customers to various applications.
