All stainless steel electric contact pressure gauge maintenance method

At present, there are many types of pressure gauges in the market, and the maintenance of various pressure gauges is not the same. Here we talk about the maintenance method of all stainless steel pressure gauges.

1, the maximum electric current through the electric contact does not allow more than 3A (ampere), otherwise the consequences of your own.

2. The pressure meter should be installed vertically. Avoid collision and vibration during handling.

3, pressure gauge should be in the ambient temperature of -40 °C - +70 °C relative humidity is not greater than 85%, and the vibration or the measured medium of the rapid pulsation of reliable contact and accurate letter reading without affecting the use of the place.

4. The electrical circuit of the pressure meter (see diagram) is carefully checked after setting up and connected, and the test operation is performed.

5, pressure gauges in the adjustment of a given value, must use slotted screwdriver.

6. When measuring the static load, the pressure meter can be used for 3/4 of the upper limit of the measurement, and 2/3 of the upper limit of the measurement can be used when measuring the alternating load. For the instantaneous measurement, the upper limit can be used.

7. The isolation device and buffer device should be added when measuring large viscosity medium and drastic fluctuation pressure.

8, pressure gauges should be regularly verified (at least once every three months)

9. Pressure gauges should always be kept dry and clean during use and properly maintained.
