Product Details
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.
