SF6 density relay test instrument is the latest high-precision
instruments, its key parts all imported from foreign countries,
used high accuracy pressure sensor and A/D,D/A transducer, combined
with 32 ARM single-clip and high speed signal dealing clip of TI,
can finish the test for SF6 Intensity Delay automatically, can
correctly test the pressure under signalizing activity, and finish
the standard pressure conversion under 0~20℃, can save and print
the test results, the whole procedure need not people control, can
automatically indentify the fault during the test. Its with the
features: high accuracy, high stability, strong reliability.
SF6 density relay calibrator, automatic density relay tester,
density relay calibrator sulfur hexafluoride, SF6 gas density relay
calibrator, SF6 density relay tester, density relay calibrator
The Characteristics of the products
1. Use 32 ARM single-clip and high speed signal dealing clip of TI
to test and control, with high integrated degree, electromechanical
integration design, with high accuracy, good reproducibility and
2. Equipped with monochrome LCD and soft keyboard man machine
interface, easy to operate, with beautiful appearance.
3. Automatically finish the conversion between pressure measurement
and 20℃, thereby finish the dynamic automatic compensation between
pressure and temperature. And display the pressure of the measured
environment, the equivalent pressure under 20℃, temperature.
4. The device automatically finish the test, do not need people's
5. Print the test results in report, and intelligent analysis the
6. Can save the test results for 50 tests, can review and print the
historical test results at any time.
7. Do not need thermostatic chamber during the test, can calibrate
the SF6 density, pressure meter at any available temperature.
8. Equipped with many kinds of transition joint, for most of the
density relay tester can do field test without disassembly.
9. Will not waste SF6 during the test, with low test cost, without
pollution to environment.
10. Can online modify the system time.
11. Can online modify the system pressure on site.
12. Its key parts all imported from foreign countries, with
13. Can test on group alarm signal , two groups atresia signal.
14. This product is portable device, easy and reliable to use, it
is the ideal equipment for SF6 density tests.
