Introduction and precautions for electric contact pressure gauges
The electric contact pressure gauge is a pressure gauge with position control, which is widely used in petroleum, chemical, metallurgical, power station and other industrial sectors or supporting electromechanical equipment. This meter is used to measure the pressure of various fluid media. When used in conjunction with the corresponding electrical devices (such as relays and contactors), the shock-resistant pressure gauge can automatically control and send a signal (alarm) to the pressure system under test (control). )the goal of. The accuracy of the electrical contact pressure value is directly related to the production quality and production safety of the product.
1. The maximum passing current of the electric contact bellows pressure gauge is not allowed to exceed 3A (amperes),
2. The pressure gauge should be installed vertically, and collision and vibration should be avoided during transportation and installation.
3. The pressure gauge should be in a place where the ambient temperature is -40℃～+70℃ and the relative humidity is not more than 85%, and vibration or the sharp pulsation of the medium measured by the shock-resistant pressure gauge has no influence on reliable contact and accurate signal reading. use.
4. After the electrical circuit of the pressure gauge is set and connected, check it carefully, and perform a trial operation.
5. When the pressure gauge adjusts the given value, it must be carried out with the help of a slotted screwdriver.
6. The pressure gauge can be used to measure up to 3/4 of the upper limit of measurement when measuring static load, up to 2/3 of the upper limit of measurement when measuring alternating load, and up to the upper limit of measurement for instantaneous measurement.
7. The diaphragm pressure gauge isolation device and buffer device should be added when measuring the medium with high viscosity and the drastically fluctuating pressure.
8. The pressure gauge should be checked frequently (at least once every three months)
9. Keep it dry and clean during use, and maintain it properly.
