YXC series Electric contact pressure gauge made by SHANGHAI AUTOMATION INSTRUMENTATION CO., LTD., is widely used in petroleum, chemical, metallurgy, power plants, machinery and other industrial sectors or mechanical and electrical equipment supporting the measurement of non-explosive hazards in a variety of fluid medium pressure. Usually, the instrument with the corresponding electrical devices (such as relays and frequency converters, etc.) supporting the use of the pressure can be measured (control) of various gases and liquid media by the instrument to achieve automatic control and signaling (alarm) purposes.

Overview

Electric contact pressure gauge SHANGHAI AUTOMATION INSTRUMENTATION CO., LTD., is widely used in petroleum, chemical, metallurgical, power, machinery and other industrial sectors or mechanical and electrical equipment supporting the measurement of non-explosive hazards in a variety of fluid medium pressure. The instrument is used with the corresponding electrical devices (such as relays and frequency converters) to achieve automatic control and signaling (alarm) for the measured pressure system [1].

Structural principle

Electric contact pressure gauge by the measurement system, indicating system, magnetic auxiliary device, shell, adjust the device and the junction box (plug seat) and other components. General electrical contact pressure gauge is used to measure the corrosion of copper and copper alloy can not play the role of gas, liquid medium positive and negative pressure, stainless steel electrical contact pressure gauge for measuring the corrosion of stainless steel does not play the role of gas, liquid medium positive and negative Pressure and the pressure reaches a predetermined value when the signal, connected to the control circuit to achieve the purpose of automatic control of the alarm.

The electric contact pressure gauge SHANGHAI AUTOMATION INSTRUMENTATION CO., LTD., is based on the spring tube in the measuring system under the pressure of the measured medium, forcing the end of the spring tube to produce the corresponding elastic deformation of a displacement, with the lever by the gear transmission mechanism and to enlarge, by the fixed gear The indication (together with the contact) is indicated by the measured value on the dial. At the same time, when it is in contact with the contact (upper or lower limit) on the set pointer (moving or moving), the circuit in the control system is disconnected or turned on to achieve automatic control and The purpose of the alarm.

Electrical principle

To control the compressor motor as an example: storage pressure to reach the lower limit automatically open, to reach the upper limit of automatic shutdown.

The control process is as follows: When the pressure reaches (or low and low), the movable contact (common male) of the electrical contact pressure gauge is connected with the lower limit contact, and the relay J1 moves and locks itself. Closed drive J3, the motor was running. When the pressure reaches the upper limit, the movable contact is connected with the upper limit contact, the relay J2 is operated, its normally closed contact is disconnected, the J1 power is cut off, its normally open point is broken, the J3 is released and the motor stops. So reciprocating, to achieve the purpose of automatic control.
