Electric contact pressure gauge is easy to be damaged. Is there any improvement method

Author: admin Source: Release time: 2016-11-28 14:11:27 Number of hits:

The most easily damaged electric contact pressure gauge is the electric contact. In order to prolong its service life, it can be improved from the following aspects

1. If the pressure fluctuation is large, damping should be added on the impulse pipe, such as installing annular pipe and adjusting valve opening properly.

2. If allowed, the upper and upper limits of the measured pressure should be larger.

3. Reduce the power supply voltage of the electrical contact. Of course, the power of the relevant relay should be replaced. Connect RC to the electrical contact to eliminate spark components

4. The effective way to reduce the current passing through the electric contact is to pass through the electronic amplifying circuit, such as driving the relay with triode or integrated circuit

2. The magnetic assisted electric contact pressure gauge is used to increase the contact torque of the electric contact through the magnetic assistance, which has relatively high electric contact power. Because the magnetic force can increase the contact suction, accelerate the contact speed, make the electrical contact reliable, eliminate the arc, and avoid the frequent action of the electrical contact due to vibration or medium pressure fluctuation.
