Pressure gauge calibrator gauge checker

Model: XY series MOQ: 1 Product Abstract: pressure gauge calibration is also known as pressure gauge calibrator or calibration pump pressure gauge, pressure gauge checker principle is the movement of the piston rod pressure increases, so to pressurizing purposes. Check the pressure gauge is used to verify the source of general gauge, test pressure up 60MPA, test vacuum up -0.08MPA. Usually in the laboratory or metrology room with precision pressure gauge (high precision up to 0.25) to detect the general pressure gauges (accurate to 1.6 or 2.5). Pressure gauge connection typically M20 × 1.5 external thread, pressure gauge checker interface was M20 × 1.5 (included with M14 × 1.5) model specification pressure transmission medium XY-6 -0.082-6MPa transformer oil XY-60 0-60MPa medicine castor oil XY-80 0-80MPa medicinal castor oil pressure gauge calibration installation: 1. check should be placed for easy operation of the table must be level. 2. Verify the working environment temperature of + 20 ± 10 ℃, the surrounding air must not contain corrosive gases. 3. The verification shall not be subject to vibration; table covered with a rubber mat required. 4. Before use, first wash with gasoline validator line, then pressure transmission medium cup filled with oil. Turning the manual hand wheel screw Check the oil is smooth; without question, be fitted with precision pressure gauge and the school. Use a pressure gauge checker: 5. Step: When testing the vacuum table: (1) Clear check inside pressure transmission medium. (2) Close the valve, open oil cup valve and hand pump screw is screwed into the cylinder. (3) Close the valve, open the valve, unscrew the screw hand pump, create a vacuum; if not spin out of time to reach the degree of vacuum, you should then close the valve, open the valve screw screwed into the hand pump in the end, and then close the valve, open the valve , unscrew the screw hand pump, and so forth precession, spin out a few times, until the desired degree of vacuum reached. When the test pressure gauge: (1) Open the oil cup valve, left-hand wheel rotation, so that the hand pump cylinder filled with oil. (2) Close the oil cup valve, open the valve, then right-handed handwheel, compressed fluid, the hydraulic effect on the pressure gauge can be verified from the indicated value of two tables.
