KSS532 Infrared SF6 Purity Sensor
KSS532 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. KSS532 adopts MEMS light
source, optical cavity with special structure and dual-channel
detector to realize space dual optical path reference compensation,
and microprocessor for signal acquisition, processing and output.
KSS532 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
and 485 output, which is convenient for customers to apply various
applications.

The sensor mounting positioning hole is installed according to the
structural dimension drawing, and the aperture is 3.2mm.
The wiring socket spacing is 2.54 m m.
The sensor should be calibrated regularly, not more than 3 months
is recommended.
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
