由测量系统、指示系统、磁助电接点装置、外壳、调整装置和接线盒（插头座）等组成。 The electric contact pressure gauge is composed of a measurement system, an indication system, a magnetically assisted electric contact device, a housing, an adjustment device, and a junction box (plug socket). The working principle of the electric contact pressure gauge is based on the spring tube in the measurement system under the pressure of the measured medium, causing the end of the spring tube to generate a corresponding elastic deformation and displacement, and the transmission is magnified by the gear transmission mechanism through the lever. The indicator (with the contacts) on the fixed gear indicates the measured value on the dial one by one. At the same time, when it comes into contact with the contacts (upper limit or lower limit) on the set pointer (moving or breaking), the circuit in the control system can be opened or closed to achieve automatic control and development. The purpose of the letter alarm. YXC series magnetically assisted electric contact pressure gauges are widely used in petroleum, chemical, metallurgy, power station and other industrial sectors or in the supporting of mechanical and electrical equipment to measure the pressure of various fluid media without explosion danger. In order to meet the different needs of the measured object, YXC series magnetically assisted electric contact pressure gauges have developed anti-vibration, corrosion-resistant, anti-vibration and There are more than 10 types of products such as isolation devices. In view of the fact that the magnetic-assisted electric contact pressure gauge not only has the characteristics of novel design, reliable structure, complete varieties and specifications, good motion stability, and strong adaptability, but also has the advantages of measurement and control, simple installation, and small maintenance, etc. The electric contact pressure gauge is a pressure measurement and control instrument unparalleled by a general pressure controller with no indication, no switching difference adjustment and no external setting device.
适用于测量无爆炸危险的流体介质的压力。 Electric contact pressure gauge is suitable for measuring the pressure of fluid medium without explosion danger. Generally, the electrical contact pressure gauge can be used with corresponding electrical devices (such as relays and contactors) to achieve the purpose of automatic control and signalling (alarm) for the pressure system under test (control). Electric contact pressure gauges are divided into two types: direct electric contact pressure gauges and magnetically assisted electric contact pressure gauges. There are two types of on-site installation and flush-mounted installation. Maximum working voltage of electric contact pressure gauge: DC220 or AC380V. Electric contact pressure gauge contact power: 10VA (resistive load), magnetically assisted type is 30VA. The control method of the electric contact pressure gauge is: upper and lower limits, double upper limit, double lower limit. The environmental conditions of the electrical contact pressure gauge are: -40 to 70 ° C, and the relative humidity is not greater than 85%. Temperature environment: When the use temperature deviates from 20 ± 5 ° C, the set point error change is not greater than 0.6% / 10%.
的结构原理：电接点压力表由测量系统、指示装置、电接装置或磁助电接点装置、外壳、调整装置和接线盒等组成。 Structural principle of electric contact pressure gauge: The electric contact pressure gauge is composed of a measuring system, an indicating device, an electric contact device or a magnetically assisted electric contact device, a housing, an adjustment device and a junction box. The working principle of the electric contact pressure gauge is based on the spring tube in the measurement system under the pressure of the measured medium, forcing the end of the spring tube to have a corresponding elastic deformation-displacement. The pointer (along with the contacts) fixed on the gear shaft indicates the measured value on the dial one by one. At the same time, when the electric contact pressure gauge is in contact with the contact (upper limit or lower limit) on the setting pointer (dynamic break or close), the circuit of the control system can be disconnected or connected to achieve automatic control and The purpose of the letter.
