KDJD-ASF6 density relay tester is an intelligent and automatic SF6 density relay calibration instrument. This instrument adopts single cycle instruction microcomputer technology, with a running speed 10 times faster than ordinary microcontrollers. It can perform on-site verification of SF6 density relays with pointer type contact output and intelligent current output, and use interrupt mode to capture the real-time action of the density relay. Therefore, the instrument measures more accurately and timely. This instrument is a portable calibration device that converts the pressure of SF6 gas at various ambient temperatures into standard values. It can also automatically calibrate SF6 density and pressure gauges.

The SF6 gas pressure at a certain temperature in a closed container can represent the density of SF6 gas. Traditionally, SF6 gas pressure at 20 ℃ is used as the standard value. During on-site verification, the measured pressure values at different ambient temperatures must be converted to their corresponding pressure values at 20 ℃ to determine the performance of SF6 density relays.

The KDJD-A intelligent SF6 density relay tester automatically completes the calibration process and is easy to use for accurate measurement.

1. The relay calibrator adopts an analog-to-digital hybrid single cycle high-speed microcontroller as its core, which has abundant resources, strong functions, and strong data processing capabilities. Because it integrates A/D, D/A, reference voltage, and analog amplification inside the microcontroller, the peripheral circuit is simple, stable, and accurate.

2. The instrument can automatically calibrate pointer and electronic density relays.

3. The initial state of the 1-3 sets of contacts of the density relay is normally open or normally closed, and the response and recovery values of the 1-3 sets of contacts can be measured simultaneously.
