Product Description

Dead Weight Tester 

I  Use

This product can be used to test general pressure gauge and pressure transmitter.


II  Structure and working principle

This product consists of ① hand pump, ② oil cup, ③ pressure output, one-way valve, ④ connecting pipeline, ⑤ base. Close the oil cup valve, rotate the handwheel to move the piston, and the resulting pressure can be transmitted to the standard instruments and tested instruments of the two pressure output nozzles, checking the pressure gauge to be tested according to the value displayed by the pressure calibrator.

Range: 0-60MPa, interface: M20 × 1.5, working environment: at 5 ~ 35 ℃, humidity ≤80%, non-corrosive place.


III  Operation and use

 1 This product should be placed on a workbench that is easy to operate and kept level.

 2 The working ambient temperature is 20 ± 10 ℃, the relative humidity is not more than 80%, and the surrounding air must not contain corrosive gases.

 3 This product must not be shaken. The workbench needs to be covered with rubber pads and fastened with screws.

 4 Use: Open the oil cup valve and turn the handwheel leftward, so that the cylinder of the pressure pump is filled with pure water.

 5 Close the oil cup valve, turn the handwheel leftward, compress the pure water, make the oil act on the pressurecalibrator and the instrument under test, and perform verification based on the display values of the two instruments.
