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.

The sensor is mounted with a positioning hole spacing of 64 mm and an aperture of 3 mm
The wiring socket spacing is 2.54 m m
The sensor should be calibrated regularly, it is recommended that it be no more than 3 months, and calibration is not required if automatic calibration is turned on for long-term operation
Do not use the sensor for a long time in an environment with a high density of dust
Please use the sensor within the range of the sensor's power supply
In order to be able to purchase the specific specifications required, please provide the following information
1) Sensor name
2) Measure the gas
3) Sensor range
For example, SW521R200, SF6, 0-100 ppm
In order to facilitate the better use of this product, V1.2 updates the calculation method of returning concentration value in the 4.3.2 MODBUS RTU protocol and the command description of reading concentration value after changing the address.
