1、 Product Overview
BR-2002Y seriesHydraulic pressure calibration tableIt is an important auxiliary equipment in pressure instrument detection work, used in conjunction with pressure standards to complete pressure instrument calibration and detection work. The calibrator uses an imported hydraulic pump as the pressure generating component, supplemented by well-designed fine-tuning, quick interface, and stabilizing valve components. Simple operation, reasonable structure, good sealing performance, wide range pressure generation system, can be widely used in industries such as metrology, scientific research, industrial and mining enterprises, and instrument manufacturing.

3、 Usage operation
1. Forward detection
Unscrew the plugs on the connectors of output 1 and output 2, open the stabilizing valve, adjust the micro adjustment to the appropriate position (middle position), and close the air delivery valve. Gently operate the lever to direct the pressure liquid to the two pressure output ports. Reinstall the standard meter and the verified meter, operate the lever to increase the pressure to around the verification point, use fine-tuning to adjust to the verification point, and test point by point until the full range is reached.
2. Return inspection
According to the regulations, after two readings at full range, slowly reduce the voltage to the calibration point with a fine adjustment, and test point by point until zero. When the adjustment cannot reduce the pressure, you can gently open the relief valve to reduce the pressure.
3. When the pressure drops slowly under high pressure, close the stabilizing valve. (First adjust the pressure to around 65MPa, stabilize for 1-3 minutes, and then slowly adjust to 60MPa)

4、 Precautions
1. The pressure calibrator should be placed on a flat and easy to operate table, avoiding use in environments with highly corrosive gases and dust particles.
2. The tested instrument should be cleaned appropriately to prevent stains from entering the detection circuit.
3. The output 1 and output 2 connectors are specialized quick connectors. When installing the instrument with end face sealing, no tools are needed. Tighten evenly with force until the sealing surfaces are tightly attached to each other, and then tighten 1-2 turns.
4. The output 1 and output 2 connectors are composed of two parts, top and bottom. When using, it is necessary to regularly check whether the lower locking screw is connected reliably. If the connection is not reliable, it may cause breakage under high pressure.

When the pressure generated by the lever is heavy, please use fine-tuning to increase the pressure, which will be easier.
