Ⅰ: Overview about the Sf6 Gas Density Relay Calibrator:
This instrument is an intelligent and fully automatic SF6 density relay calibration instrument. The instrument adopts single cycle instruction microcomputer technology, and its operation speed is 10 times of that of ordinary single chip microcomputer. It can conduct on-site verification on SF6 density relay with pointer contact output and intelligent current output, and use interrupt mode to capture the action of density relay in real time, so the instrument can measure more accurately and timely. This instrument is a portable calibration instrument for standard conversion of SF6 gas pressure under any ambient temperature, and it can also automatically calibrate SF6 density gauge and pressure gauge.
The SF6 density relay calibrator completes the calibration process automatically, which is convenient for use and accurate for measurement, and the Chinese menu operation is simple and clear.
Ⅳ: Functional Characteristics About The Sf6 Gas Analysis Density Relay Calibrator:
1. The relay calibrator uses the analog digital mixed single cycle high-speed single chip microcomputer as the core, which is rich in resources and powerful in function, and has strong data processing capability. Because it integrates A/D, D/A, reference voltage, and analog amplification into the single chip microcomputer, the peripheral circuit is simple, stable, and accurate.
2. The instrument can automatically calibrate the pointer density relay.
3. The initial state of 1~3 groups of contacts of the density relay is in any form (normally open or normally closed), and the response value and recovery value of 1~3 groups of contacts can be measured at the same time, so the instrument can adapt to the full automatic calibration of all new and old forms of density relays.
4. The instrument adopts a 7-inch color touch screen, which is simple and convenient to use.
5. During measurement, the instrument displays the current pressure, the corresponding pressure at 20 and the ambient temperature. Solved the problem of on-site calibration of SF6 density relay.
6. The test process is automatic measurement, avoiding errors caused by human factors.
7. The instrument can store 500 groups of measurement data, making each measurement traceable.
8. The instrument can upload the test data to the U disk through the USB interface, and automatically generate a special test data table.
9. The instrument can calibrate the normal temperature pressure gauge and density gauge at any ambient temperature.
10. All instrument pipelines adopt imported quick connectors, which are easy to connect and have small air leakage rate.
11. The instrument has a clock function, which can be corrected at any time.
12. The instrument has self-calibration function. After the instrument is used for a long time, it can be calibrated and corrected to ensure the calibration accuracy of the instrument.
13. The instrument adopts high-precision pressure sensor and temperature sensor.
14. The instrument is equipped with a variety of switch transition connectors, and most switches can be calibrated without disassembly.
15. The instrument has a built-in high-capacity lithium battery and an AC/DC dual-use design, which can be calibrated while charging, expanding the use space of the instrument and facilitating on-site calibration.
