YXCWidely used in industrial sectors such as petroleum, chemical, metallurgical, and power stations, or in the measurement of pressure of various fluid media without explosion hazards in mechanical and electrical equipment. Usually, instruments can be used in conjunction with corresponding electrical components (such as relays and contactors) to achieve automatic, control, and alarm functions for the measured (controlled) pressure system. In order to adapt to the different needs and requirements of the tested objects, this system instrument has developed more than 10 types of products, including anti vibration, corrosion-resistant, corrosion-resistant and seismic resistant, as well as isolation devices, on the basis of the original ordinary and professional types.
This series of instruments not only has the characteristics of novel design, reliable structure, complete variety, stable operation, and strong adaptability, but also has the advantages of combined measurement and control, simple installation, and low maintenance. Therefore, it is an unparalleled pressure measurement and control instrument compared to general pressure controllers without indication, switching difference adjustment, and external setting devices.

Structural principle
The instrument consists of a measurement system, an indication system, a magnetic assisted electrical contact device, a housing, an adjustment device, and a junction box (plug socket).
The working principle of the instrument is based on the spring tube in the measurement system, which, under the pressure of the measured medium, causes the end of the spring tube to produce corresponding elastic deformation and displacement. With the help of a pull rod transmitted through a gear transmission mechanism and amplified, it is indicated by the fixed gear
(Along with the contacts) indicate the measured values on the dial one by one. At the same time, when it comes into contact with the contact point (upper or lower limit) on the set pointer (dynamic breaking or dynamic closing), it causes the circuit in the control system to be disconnected or connected, in order to achieve automatic control and send alarm signals.
