The hydraulic machine of the electric contact pressure gauge old bad, an oil spill, and two pointer does not return, I personally think that is the quality of table or hydraulic diaphragm was too frequent starting impact times too much damage, used in hydraulic machine is not reliable electric contact pressure gauge. Present your valuable comments or suggestions, and Solutions
Due to the frequent impact of rapid change of pressure, the common electric contact pressure gauge is easily damaged. A damping electric contact pressure gauge or an electric contact pressure switch shall be selected.
The hydraulic machine out of pressure is not too stable, this causes the pressure gauge frequently in that swing, and the electric contact pressure gauge used in pressure fluctuation environment is little use to play its normal life
With an electronic pressure sensor, or with a switch, or with a pressure relay (a control switch), add a valve to the front of the meter, which is not used at all. Switch off when you check the switch.
