100ppm Range SF6 Sensor High Efficiency Sulfur Hexafluoride Sensor with 10.6um Infrared Absorption
KSS525 Infrared SF6 Gas Sensor Module
KSS525 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. KSS525 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. KSS525 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.
