Product Description

 

 

The fully automatic SF6 density relay calibrator is an intelligent SF6 density relay calibrator. This instrument uses pressure sensors and high-speed A/D converters, combined with a 32-bit microprocessor, to perform performance verification on various SF6 density relays. It can accurately measure the pressure value at the current temperature when the signal is activated, automatically convert the standard pressure at 20 ºC to the ambient temperature, and print and store test data in real time for reference. At the same time, it can automatically identify faults during the testing process.
 
This product is easy to carry, simple to operate, has high testing accuracy, strong stability, and good reliability, reflecting the characteristics of the instrument being "intelligent".

Performance characteristics
1.This product uses a 32-bit microprocessor and TI's high-speed signal processing chip for detection and control, with a high degree of integration. Mechatronics design, high precision, good repeatability, and high reliability.
2. Equipped with a large LCD screen and a rotating mouse (one click shuttle) human-machine interface, the operation is simple, the interface is beautiful, and the parameters and status are clear at a glance.
3. Automatically complete pressure measurement and 20 ºC value conversion, thus achieving dynamic automatic compensation between pressure and temperature. And display the pressure at the tested ambient temperature, the pressure at the ambient temperature of 20 ºC, and the ambient temperature. Solved the problem of difficult on-site calibration of SF6 gas density relays.
4. The testing process is automatically completed by the instrument without manual intervention, avoiding tedious manual air circuit adjustment operations.
5. Adopting metal quick plug connectors effectively avoids the locking phenomenon of plastic connectors in low temperature environments.
6. Print test results in Chinese character report format and perform intelligent analysis on the test results.
7. It can store 50 sets of test results simultaneously and has power down data protection function, which can query and print previous test results in real time.
During the verification process, no constant temperature chamber is required, and SF6 gas density relays and pressure gauges can be calibrated within the effective temperature range.
9. Equipped with multiple types of transition joints, most density relays for switches can be verified on-site without disassembly.
10. The verification process consumes less gas, does not waste SF6 gas, has low testing costs, and is environmentally friendly.
11. It has the function of online modification of the system clock.
12. It has the function of online modification of system pressure and can be corrected on-site.
13. The core components are imported,.
14. Can simultaneously test one set of alarm signals and two sets of lockout signals.
15. This product is a portable tool that is convenient and reliable to use, and is the choice for SF6 density relay calibration.
