8 советов по установке манометра

1, The ambient temperature of the instrument is -4-70°C, if it deviates from this operating temperature by 20± 5°C , the additional temperature error should be considered.

2, The pressure gauge should be installed vertically and try to keep the same horizontal position as the measuring point.

3, Otherwise, the additional error cased by the liquid level difference should be included when measuring the liquid pressure.

4,The normal measuring range of the instrument: when measuring stable pressure, it does not exceed 3/4 scale value. when measuring stable pressure, it does not exceed 3/4 scale value. When measuring fluctuating pressure, it does not exceed 2/3scale value.

5, To avoid damage, the pressure gauges should be protected from vibration and collision.

6,When the pressure gauge is used for measuring impulse pressure and instantaneous fluctuation pressure, to avoid the pressure gauge life, the connection should be added buffering device.

7, Under conditions of mechanical vibration and pressure fluctuations, we should select shock-resistant pressure gauge. The shock- resistant pressure gauge is filled with glycerin and silicone oil.

8, when use a shock resistant pressure gauge, in order to not affect the pressure gauge performance, the top of oil seal should be cut flat, and let it connect to the atmosphere.

9,When abnormal phenomena occurs during operation, should find our the reasons, and re-inspect, qualified before use.
