Advantages of the infrared SF6 sensor compared to the principles of electrochemistry and negative corona discharge:
l Infrared Spectral Absorption Principle (NDIR).
l Dual wavelength with temperature compensation.
High reliability, no cross reaction with other gases.
l Compared with electrochemical sensors, sulfur hexafluoride sensor infrared sensor life of up to 10 years.
l High cost performance, affordable preferential prices.
l Compared with electrochemical sensors, sulfur hexafluoride sensors save after-sales maintenance costs.
l Digital and analog output mode is optional, convenient for secondary development and application.
l Micro structure, low power design.
No radiation source, no secondary hazards.
Compared with the thermal conductivity principle, SF6 infrared sensor (WFS-S1-S) has significant advantages:
l Infrared SF6 purity sensor is small in size.
l Infrared SF6 purity sensor Low power consumption, battery powered.
l Infrared SF6 purity sensors do not require a large heating system.
l Infrared SF6 purity sensor operating temperature wide (-20-+60°C).
l More than 3 years of calibration cycle, no need to check the instrument frequently.
High reliability and stability, no daily maintenance of SF6 purity analyzer.
