SF6 gas sensor

Compared to a single wavelength beam,dual wavelength Dual beam technologyIt can avoid drift caused by aging of the light source, contamination of the sampling pool and detector surface. The monochromatic light of a specific wavelength modulated by the reference channel will not absorb the measured gas. It generates a stable signal that is only affected by external factors and is not affected by the measured gas.

Infrared SF6 sensors (sulfur hexafluoride sensors) have high reliability, long lifespan, and high cost-effectiveness. Not affected by H2O, alcohol, CO2 gas interference. It is widely used in SF6 gas leakage monitoring and alarm systems (0-100ppm) for power equipment, SF6 leak detectors (0-50ppm), and SF6 leak detector purity analyzers (0-100%). Almost all power equipment manufacturers who have tested our SF6 sensors have chosen to purchase our products and services. They have SM smartODUL^BASICType, SMC-smartMODUL^CONNECTType, SMF-smartMODUL^FLOWType, SMP-smartMODUL^PREMIUMType.

The principle of SF6 sensor from SmartGAS company in Germany is based on infrared spectroscopy, which is the principle of laser! Compared with the electrochemical principle, this infrared based sulfur hexafluoride sensor has the following advantages:
Advantages of Infrared SF6 Sensor:
1. Principle of Infrared Spectral Absorption (NDIR)
2. Dual wavelength with temperature compensation
3. High reliability, no cross reaction with other gases.
4. Compared with electrochemical sensors, sulfur hexafluoride sensors and infrared sensors have a lifespan of up to 10 years
5. High cost-effectiveness and affordable discounted prices.
6. Compared with electrochemical sensors, sulfur hexafluoride sensors save on after-sales maintenance costs
7. No radiation source, no harm
8. Micro structure, low power consumption
9. Digital and analog output.
The commonly used model for digital sulfur hexafluoride sensors in the power industry is SM-SF6. Sulfur hexafluoride sensors SM-SF6, SMC-SF6, SMF-SF6, SMP-SF6

At present, some power service providers are still using sulfur hexafluoride sensors based on electrochemical principles, but these SF6 sensors cannot meet the low range SF6 testing requirements of the power industry, such as 0-50PPM and 0-3000PPM. However, SF6 sensors based on infrared principles can be customized for these ranges.
