- yfy-40yt pressure gauge verifier description:

I. main purpose

The calibrator of the oil-blocking pressure gauge adopts the manual plunger pump under double lever to make pressure, which is convenient and labor-saving. The instrument itself is equipped with a secondary oil-water isolation device, which has reasonable structure, neat layout and stable and reliable performance. It is an ideal and practical measuring equipment for all levels of measuring departments, factories, mines, enterprises and institutions to calibrate pressure gauges, oxygen gauges and other oil-forbidden pressure gauges.

Ii. Performance and technical indicators

1. Working medium: clean instrument oil or transformer oil.

2. Strength and sealing performance:

After fully removing air, the calibrator is pressurized to the test pressure specified in table (1) for 10 minutes for strength and tightness. From the 6th minute, the pressure drop within 5 minutes shall not be greater than that specified in table (1)

3. Performance of working pressure seal:

According to the test pressure specified in table (2), step by step, the pressure drop shall not exceed 1% of the load at each grade for one minute

Table 2

Three, structure principle

Ban the oil pressure gauge verification according to the principle of PASCAL, using oil-water separation, through two levels of oil and water separation device, checking oxygen gauge, pressure gauge, tubing and conduit road transfer pressure pipeline points, the water table joint is given by the school oxygen in the verification of oxygen table and the oil pressure gauge with, joint in the pipe line connection standard pressure gauge and calibrated pressure gauge are used.

- ybs-c digital pressure gauge description:

1.- ybs-c series digital pressure gauges for ac-dc portable instruments.

2. The high-performance microprocessor makes continuous corrections to the performance and technical indicators of the instrument.

Ensure long time and wide temperature range of the instrument without affecting the accuracy of the instrument.

3. Low power consumption. The battery adopts imported nickel-metal hydride high energy battery to ensure the instrument to work in a long time.

4. Constant current charging, with the function of automatic shutdown and automatic protection for over charge and under voltage of the battery,

Ensure that the battery is not damaged due to overcharge or under voltage, and the battery life is long.

5. Micro power consumption under voltage automatic protection function, to ensure that the meter even if the operator for some reason and continue to boot

Long will not damage the battery due to undervoltage.

6. The instrument has a rich range of functions.

7. The software is rich in content, simple and clear to operate.

8. Thin film panel touch switch, novel style, long key life.

9. Adjust the full range directly on the panel
