The desktop air pressure calibration platform is an important auxiliary equipment in the testing of pressure instruments. It is used in conjunction with the pressure standard to complete the calibration and testing of pressure instruments.

The lever of the desktop air pressure test bench drives the piston in the large chamber to reciprocate to generate pressure or vacuum. The pressure or vacuum is output through the switch, and the pressure or vacuum is output through the regulator valve to the fine adjustment and pressure output interface. It is supplemented by delicately designed fine-tuning, fast interface, and pressure stabilizing valve. The advantages of simple operation, reasonable structure and good sealing performance can be widely used in measurement, scientific research, industrial and mining enterprises and instrument manufacturing industries.

Technical indicators of desktop air pressure calibration platform

2.1 Pressure range: -0.1~600KPa -0.1~2.5KPa -0.1~10MPa, -0.1~6MPa, -0.1~4MPa, -0.1~1.6MPa, contact customer service for more ranges.

2.2 Adjust sensitivity: min 10 Pa

2.3 Dimensions: 400×300×180 (length×width×height)

2.4 Weight: 6kg

3. Operation

3.1. Positive pressure detection

Press the switch in, unscrew the plugs on the output 1, output 2, and output 3 connectors, connect the standard meter and the tested meter, open the regulator valve, adjust the fine adjustment to the appropriate position (middle position), and close the air valve . For example, the pressure range is -0.095~6MPa when the operating lever is pressurized to 4~5MPa, use fine-tuning to adjust the pressure to about 6.5MPa, stabilize for 1~2 minutes, use fine-tuning to the verification point, close the pressure regulator, and check point by point. Zero point.

3.2. Negative pressure detection

Pull out the switch, unscrew the plugs on the output 1 and output 2 connectors, connect the standard meter and the tested meter, open the pressure regulator valve, adjust the fine adjustment to the appropriate position (middle position), and close the empty valve. The operating lever is vacuumed when the pressure reaches about -0.095MPa. Stabilize for 1 to 2 minutes, use fine-tuning to adjust to the verification point, close the regulator valve, and detect point by point to zero.

3.3. In the high pressure state, when the pressure drops slowly, close the pressure regulator valve. (First, fine-tune the pressure to about -0.1MPa, and then slowly adjust to -0.095MPa after 1~2 minutes of stabilization)

4. Matters needing attention

4.1 The inspection table should be placed on a flat and easy-to-operate table to avoid entering the environment with highly corrosive gas and dust particles.

4.2 The inspected instrument should be properly cleaned to prevent dirt from entering the detection loop. ,

4.3 The output 1 and output 2 nozzles are dedicated quick connectors, and the end faces are sealed.

When installing the instrument, you don't need to use any tools to tighten it evenly. About 1 to 2 turns when the sealing surfaces are close to each other.

4.4 The output 1 and output 2 nozzles are composed of upper and lower two pieces. When using, always check whether the lower locking screw is connected reliably. If the connection is unreliable, it may cause collapse under high pressure. To

4.5 When the leverage pressure is heavy, please use the fine-tuning boost, which is easier.
