How to connect the electric contact pressure gauge? The electric contact pressure gauge has three wiring, one is public, the gauge pin is adjustable, may adjust one gauge pin to 0.4 m, connects the low voltage start control relay, another gauge pin adjustment to 0.6 m, connects the high voltage stop relay, public line is the high and low voltage control of the public line.
The upper limit is on the right, the lower limit is on the left, and the black pointer in the middle indicates the actual pressure. When the actual pressure is above the upper limit, it is connected with the upper limit and disconnected from the lower limit. When the actual pressure is between the upper and lower limits, the common end is disconnected from the upper and lower limits. When the actual pressure is below the lower limit, the public end is connected to the lower limit and disconnected from the upper limit. The electric contact pressure gauge is used to control the upper and lower limit pressure. It is not enough to have an electric contact pressure gauge, but also to have a matching control box.
The specific technical parameters are as follows:
1. Accuracy: 1.6 Grade
2, measuring range: -0.1 ~ -0 ~ 60MPa
3, power supply voltage: 380VIAC; 220V/DC
4, contact power: 10VA, 30VA (magnetic assistant type)
5, model: # #
Measure the pressure or negative pressure of liquids, gases or vapors that do not corrode copper and steel and their alloys, and signal or turn on the control circuit when the pressure reaches a predetermined value. When the environment vibration is big, can choose magnetic-assisted electric contact pressure gauge.
