KSS520 Infrared SF6 Gas Sensor Module

1.Overview

SF6 gas is widely used as an insulating medium and arc extinguishing gas in power equipment, especially in high-voltage circuit breakers, transformers, transformers, capacitors, arresters, fuses, etc. If leakage occurs, the pressure of the equipment is reduced and the insulation capacity is reduced; Pollute and destroy the atmospheric environment, increase the greenhouse effect; Accumulation in low-level spaces, resulting in accidents such as lack of oxygen in the brains of staff and even rapid asphyxiation; Under the influence of partial discharge, high temperature and other factors, SF6 gas will produce highly toxic decomposition substances such as SF4, SF2, SOF2, etc.

KSS520 is a gas sensor module using NDIR infrared absorption detection principle, which determines the concentration according to the infrared radiation absorption of 10.5um by SF6 gas. KSS520 adopts MEMS light source, special structure optical cavity and dual-channel detector to realize space dual optical path reference compensation, and microprocessor for signal acquisition, processing and output. KSS520 is small in size, low in power consumption, and has UART, 4 to 20mA interfaces, and can also customize analog voltage output; Provides digital calibration zero and sensitivity functions, and manually implements calibration zero function.

KSS520 can be widely used in SF6 gas leak detection and other occasions SF6 gas concentration analysis in the power industry.
