YX, YXC-60.100.150 electric contact pressure gauge, magnetic-assisted electric contact pressure gauge, composed of two independent parts: ordinary pressure gauge and contact device. It works stably and reliably, and is widely used to measure the pressure of liquids, gases and other media that have no corrosive effect on copper, steel and their alloys and to send out electrical signals. It is used in automatic control systems to connect control circuits to achieve the purpose of automatic control alarms.
The electrical contact signal pin of the electrical contact pressure gauge device is equipped with an adjustable permanent magnet, which can increase the suction force of the contact and accelerate the contact action, so that the contact is reliable, eliminates the arc, and can effectively avoid the instrument vibration due to the working environment Or the medium pressure pulsation causes frequent switching off of the contacts. Therefore, the electric contact pressure gauge has the advantages of reliable action, long service life, and large contact switch power.
Performance and principle of electric contact pressure gauge
The working principle of the electric contact pressure gauge is that under the pressure of the measured medium, the spring tube of the measuring system forces the end of the spring tube to produce corresponding elastic deformation-displacement, which is driven by the gear transmission mechanism with the help of a pull rod and amplified, and fixed by The pointer (together with the contact) on the gear shaft will indicate the measured value on the dial. At the same time, when it is in contact (or disconnected) with the contact (lower limit or upper limit) on a given needle, the relay and contactor in the circuit system (turning on or off the power supply) make The control mechanism makes corresponding actions (working or not), and can send out electric signals to achieve the purpose of white movement control and alarm.
