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. Leakage occurs, equipment pressure
decreases, 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.
SF6 Purity Meter is a gas sensor module using NDIR infrared
absorption detection principle. The concentration is determined
according to the absorption of SF6 gas at 10.5um. The single-light
source and dual-channel structure of MEMS light source,
dual-channel pyroelectric detector and optical gas chamber are used
to realize the reference compensation of the spatial dual optical
path. Microprocessors perform signal acquisition, processing, and
output, with temperature compensation and nonlinearity correction.

LENGTH * WIDTH * HEIGHT (MM) = 80 * 43 * 40
See structural dimension drawing.
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
required, please provide the following information
1) Sensor name 2) Sensor range 3) Measurement accuracy, etc
For example, KSS5F6, 90%~100%, 2% accuracy, etc
