Product introduction
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.
Alternative name

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 strong reliability.
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 intervention 
5. Print the test results in report, and intelligent analysis the results.
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 reliable property.
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.

Product information

1. Check the toolbox before go to the scene, including the volume of small nitrogen gas storage, bring all switches and instruments used for transition joints.
2. terminal block corresponding alarm signal lines, blocking the signal line should be disconnected from the terminal to prevent the secondary circuit and signal lines as a loop to impact the test.
3. Must be vertical, can’t be horizontal.
4. Do not have too much vibration during the operation process.
5. Follow the instructions to use gas cylinders.
