Magnetic-assisted electric contact pressure gauge
Product Introduction
Magnetic-assisted electric contact pressure gauges are widely used in petroleum, chemical, metallurgy, power stations and other industrial sectors or in supporting electromechanical equipment to measure the pressure of various fluid media without explosion hazard. Usually, the instrument is used in conjunction with the corresponding electrical devices (such as relays and contactors, etc.) to achieve automatic control and signal (alarm) purposes for the pressure system to be measured (controlled).
In order to adapt to the different needs and requirements of the tested objects, this series of instruments have developed anti-vibration, corrosion-resistant, corrosion-resistant and anti-vibration types and isolation devices on the basis of the original common type and special type. There are a total of more than 10 types of products.
In view of the fact that this series of meters not only has the characteristics of novel design, reliable structure, complete varieties and specifications, good action stability, and strong adaptability, but also has the advantages of measuring and controlling, simple installation, and small maintenance. Therefore, it is generally without instructions. , Pressure measurement and control instrument for pressure controller without switching difference adjustment and without external setting device.
Performance and characteristics
The meter is composed of measuring system, indicating device, magnetic-assisted electric contact device, shell, adjusting device and junction box (plug seat).
working principle
Based on the spring tube in the measuring system under the pressure of the measured medium, the end of the spring tube is forced to produce corresponding elastic deformation-displacement, which is driven by the gear transmission mechanism with the help of a pull rod and amplified, which is indicated by the fixed on the gear shaft The pointer (together with the contact) will indicate the measured value on the dial one by one. At the same time, when it is in contact with the contact (upper or lower limit) on the setting pointer (moving off or on), the circuit in the control system can be disconnected or connected to achieve automatic control and transmission. Letter the purpose of the alarm.
