Two days ago, a customer from Hebei called to purchase a batch of electric contact force gauges, including shock resistant electric contacts, diaphragm electric contacts, stainless steel electric contacts, ammonia electric contacts, etc. It is necessary to send a signal when the measured medium pressure reaches the predetermined value, connect the control circuit, and achieve the purpose of automatic control alarm. Previously, the customer learned about our manufacturer through a neighboring company and provided feedback that the electric contact pressure gauge series produced by Jiangsu Hongrui has good quality and stable performance. Therefore, this time they are very confident in purchasing. Today we will explain to you the working principle of the electric contact pressure gauge product.

The purpose of the electric contact pressure gauge produced by the company is to measure the pressure of various fluid media without explosion hazards in industrial sectors such as petroleum, chemical, metallurgy, and power stations, or in the matching of mechanical and electrical equipment. The instrument, when used in conjunction with corresponding electrical components, can achieve automatic control and signaling (alarm) of the measured pressure system.

The working principle of the electric contact pressure gauge produced by the company:

The electric contact pressure gauge itself consists of a measurement system, an indication system, a magnetic electric contact device, a housing, an adjustment device, and a junction box.

Its working principle is based on the spring tube in the measurement system, which is forced to produce corresponding elastic deformation displacement at the end of the spring tube under the pressure of the measured substance. With the help of a pull rod and gear transmission and amplification, the measured value is gradually indicated on the dial by the indicator pointer fixed on the gear shaft. At the same time, when it comes into contact with the contact on the set pointer, it causes the circuit in the control system to be disconnected or connected, in order to achieve automatic control and send alarm signals.

The main technical parameters of the electric contact pressure gauge products produced by the company are:

1. Instrument outer diameter: 60, 100, 150
