Sulfur hexafluoride SF6 gas density relay calibration machine tester/SF6 density relay calibrator

The automatic SF6 density relay calibrator is a kind of intelligent SF6 density relay calibrator. This instrument adopts pressure sensor and high speed A/D converter, combined with 32-bit microprocessor, can verify the performance of various SF6 density relays, can accurately measure the pressure value at the current temperature when the signal action, automatically complete the conversion of the ambient temperature to the standard pressure at 20ºC, and can print and store the test data for reference. At the same time, the fault in the test process is automatically identified.

This product is convenient to carry, simple to operate, high test accuracy, strong stability, good reliability, reflecting the instrument "intelligent" characteristics.

Performance characteristics
1. This product uses 32-bit microprocessor and TI's high-speed signal processing chip for detection and control, with high integration degree. Mechanical and electrical integration design, high precision, good repeatability, high reliability.
2. Equipped with large Chinese LCD screen and rotary mouse (one-click shuttle) man-machine interface, simple operation, beautiful interface, parameters and status at a glance.
3. Automatically complete the pressure measurement and 20ºC value conversion, so as to complete the dynamic automatic compensation between pressure and temperature. It also shows the pressure at the measured ambient temperature, the pressure at the ambient temperature at 20 ° C, and the ambient temperature. The problem of SF6 gas density relay field calibration is solved.
4. The test process is automatically completed by the instrument, without manual intervention, avoiding tedious artificial gas path adjustment operation.
5. Metal quick-insert joints are used to effectively avoid the locking phenomenon of plastic joints in low temperature environment.
6. Print test results in Chinese character report form, and conduct intelligent analysis of test results.
7. Can store 50 groups of test results at the same time, and has power down data protection function, can query and print the previous test results in real time.
8. No constant greenhouse is required during the verification process, and SF6 gas density relays and pressure gauges can be verified within the effective temperature range.
9. Equipped with various types of transition connectors, the density relay of most types of switches can be verified on site without disassembly.
10. Less gas consumption in the verification process, no waste of SF6 gas, low test cost, good for the environment.
11. The system clock can be modified online.
12. With online modification system pressure function, can be corrected on site.
13. The core components are imported components.
14. Can test a set of alarm signals and two sets of blocking signals at the same time.
15. This product is a portable tool, easy to use and reliable, is the choice of SF6 density relay calibration.
