SF6 Sensor module -SF6 infrared sensor 0-5000ppm


Product Introduction:

SF6 Sensor module adopts the infrared absorption detection principle of NDIR and combines advanced optical path, precision circuit and intelligent software to form a general infrared SF6 sensor module. This product uses single light source, double channel detector, measurement and reference signal processing, with good linearity and temperature compensation, even in harsh temperature and environmental conditions, can also obtain stable and reliable measurement results. NDIR products with good selectivity, high sensitivity, no oxygen dependence, long life and so on.

* Models:JXM-SF6

* Minimum order quantity: 1 piece

* Delivery time: within 24 hours

Precautions for installation and use
The SF6 infrared sensor 0-5000ppm interface adopts a single row of pin spacing of 2.54mm;
Do not use the sensor for a long time in an environment with high dust density. Use the sensor within the power supply range and pay attention to the power supply polarity.


1. Reporting method
The gas module is divided into two modes: active reporting and passive inquiry. The default mode is active reporting.
Passive query instruction:
FF 01 03 02 00 00 00 00 05 (This command switches to query upload)
FF 63 63 00 00 6F 6B 0D 0A (Return reply frame indicates successful setting)
Active report instruction:
FF 01 03 01 00 00 00 00 04 (This command switches to active upload)
FF 63 63 00 00 6F 6B 0D 0A (Return reply frame indicates successful setting)

2.PWM Output (Example)
SF6 concentration output range: 0ppm to 5000ppm SF6
Period: 1004ms±5%
The formula of how to obtain the current SF6 concentration through PWM is as follows:
Forward pulse width =PPM concentration value /5+2ms;

3. Scope of Application:
Can be widely used in hVAC refrigeration replacement risk control system, indoor air quality monitoring, agricultural and animal husbandry production process monitoring, can be installed in intelligent buildings, ventilation system, controller, wall hanging use, robots, automobiles and other applications.
