Product Details

SF6 Gas Analyzer

For SF6 Swith SF6 Density Relay Intelligent Calibrator

The instrument uses a high-precision pressure sensor and a high-speed A / D converter, combined with a 32-bit high-performance microprocessor to perform performance verification on various SF6 density relays, and can accurately measure the pressure value at the current temperature when the signal is activated. It can convert any ambient temperature to the standard pressure at 20 ℃, and can immediately print and store the test data for reference, and at the same time automatically identify the faults during the test. This product is easy to carry, simple to operate, high in test accuracy, strong in stability and good in reliability, reflecting the "intelligent" characteristics of the instrument.

Features

1. High-performance 16-bit single-chip microcomputer is used for detection and control. The core components are imported components with high precision, good repeatability and high reliability.

2. Equipped with a monochrome LCD screen and a soft keyboard man-machine interface, the operation is simple and the interface is beautiful. All parameters and status are clear at a glance.

3. The pressure measurement and 20°C value conversion are completed automatically, thus completing the dynamic automatic compensation between pressure and temperature. It also displays the pressure at the measured ambient temperature, the pressure at 20°C, and the ambient temperature. Completely solved the problem of SF6 gas density relay on-site calibration is difficult

4. All testing processes are automatically completed by the single-chip microcomputer without manual intervention, avoiding the cumbersome manual gas path adjustment operation.

5. Data collection sound prompt function, the instrument will send out a beep prompt every time a data is recorded.

6. Can store 32 test results at the same time, and have power-off data protection function, can query and print the previous test results at any time.

7. With the function of communication with the computer, the data can be uploaded to the computer through the 232 communication port or the USB communication port to form a complete Word document test report.

8. No constant temperature room is required during the calibration process, and the SF6 gas density relay and pressure gauge can be verified within any effective temperature range.

9. Equipped with various types of transition joints, the density relays of most types of switches can be verified on site without disassembly.

10. In addition to the density relay calibration function, this instrument also has a 20 ℃ pressure gauge calibration and normal temperature pressure gauge calibration functions

11. With the function of modifying the system clock online ;. With online modification of system pressure.

12. Two temperature measurement modes: automatic measurement of test ambient temperature, infrared temperature measurement can also be used to ensure the accuracy of test results

13. The professional design of the gas cylinder pressure relief valve can withstand a pressure of 15MP (150 kg) and the low pressure output is adjustable. It is suitable for the calibration of the measurement room with nitrogen and other test gases

14. It can test one set of alarm signal and two sets of blocking signal at the same time.

15. This instrument is a portable tool, easy to use and reliable, it is a necessary equipment for SF6 density relay verification.
