Product Description

SF6 Gas Dew Point Decomposition and Purity Multifunctional Test Set

I.Description
SF6 comprehensive tester combines the tests of humidity of SF6, purity of SF6 and it integrates the functions which were originally fulfilled by tow instruments into one instrument. One site measurement can fulfill the test of three targets. It greatly saves the gas in the equipment, reduces the work amount of the users and improve the work efficiency.
SF6 comprehensive tester enjoys the excellent capabilities because it fully adopts the best foreign sensor, Finnish Vaisala for humidity, the thermal conductivity sensor with temperature compensation for purity are the imported products. It adopts the LCD display with real-time display of all parameters. It enjoys the overall fool-operation and large storage of information. It has chargable batteries inside for either alternating or direct current.


II.Two Measurement Principle
The basic principle of ATSM902 Type SF6 tester for measuring purity is to define the contents according to the heat conducting rate of all gases. The heat conducting rate of SF6 is the lowest in the gas, so when the heat conducting rate of the background gas is basically kept stable, the heat conducting rate will be lower if the content of SF6 in the hybrid gas is higher. The density of SF6 can be tested according to it.
 

Component	Heat conducting rate	Component	Heat conducting rate
Air O2 NH3 CH4 He H2	1.000 1.028 1.040 1.450 5.530 6.803	SF6 SO2 H2S Ar CO2 H2O CO N2	0.342 0.350 0.540 0.665 0.704 0.771 0.958 0.989

   Relative heat conducting rates of normal gases (With the air at 120ºC as the reference)
The sensor components of the ATSM902 gas analyzer are equipped in a firm thermostatic chamber, and it guarantees that the sensor can steadily work in the adverse environment.
The hydrogen sensor component is a stainless steel structure with two same sensing components inside, sensing component for measurement and sensing component for reference. There is the thermal resistor with high reliability equipped in each sensor component. These corresponding thermal resistors form the measurement arm of the bridge type circuit, and the unbalanced current of the bridge type circuit can be adopted to measure the relative capability of the sampled gas conducting heat from the thermal resistor to the surface of the sensor component. One end of the sensor with the equipped thermal resistor is sealed and the sampled gas will extend to get in in order to reduce the influence of the flow change of the sampled gas to the minimum.
