Product introduction:

 

 

 

Fmc-8s intelligent SF6 density relay verifier is an intelligent automatic SF6 density relay verifier. This instrument USES microcomputer technology, can carry on the calibration to each kind of SF6 density relay, as well as carries on the standard conversion to the SF6 gas pressure under the arbitrary ambient temperature one kind of portable calibration instrument, also provides the convenience for the SF6 electrical product production, the safe movement, the pre-test and the maintenance.

 

In a closed container, SF6 gas pressure at a certain temperature can represent the density of SF6 gas. In order to be unified, habits often make 20 ℃ when SF6 gas pressure as scale values. Check at the scene, under the different environment temperature, the measured pressure value will be converted to the pressure value of the corresponding at 20 ℃, to judge the performance of SF6 density relay. The fmc-8s intelligent SF6 density relay calibrator performs this process automatically, accurately and flexibly. This instrument can not only check the SF6 density relay, but also has the function of checking the pressure gauge and density meter and the self-calibration of the instrument. In this way, it can not only be used in one machine, but also avoid the problem of sending the instrument for inspection and returning it to the factory for inspection.

 

 

 

Functional description:

 

 

 

This tester USES high speed single chip microcomputer as the core of the measurement and control system, high degree of automation, good repeatability, high reliability.

 

2. The instrument can test relative and absolute pressure relays.

 

3. The instrument adopts imported touch color LCD, and the user-friendly interface is easy to operate (7-inch true color touch screen).

 

4. The instrument can verify the SF6 density relay under manual temperature setting and automatic collection temperature.

 

5. The instrument has data storage function (it can store 50 groups of data) and power off data protection function, which is convenient for future query of measurement data.

 

6. The instrument can upload test data to PC through rs-232 interface, and automatically generate special test data table.

 

7. The instrument can check the pressure gauge and density gauge at room temperature, and print the test results in the form of report.

 

8. Imported quick couplings are adopted for all instrument pipelines, which are convenient to connect and do not waste gas in the calibration process.

 

9. The instrument has internal clock function, and can also modify the clock online.

 

The instrument has the function of checking. After using the instrument for a long time, the instrument can be calibrated and corrected to ensure the calibration accuracy of the instrument.

 

11. The instrument USES high-precision pressure sensor and the world's advanced magnetic fluid pressure control components.

 

12. The instrument is equipped with a variety of switch transition joints, easy to operate and use.

 

13. The instrument has relay contact live test (no need to break the secondary dc DC110V/220V power supply when collecting signals) and no live test function. When the contact is not live, the optional DC24V and DC110V power supplies are provided internally.
