Electric contact pressure gauge is suitable for measuring the pressure of fluid medium without explosion danger.

经与相应的电气器件(如继电器及接触器等)配套使用,即可对被测(控)压力系统实现自动控制和发信(报警)的目的。 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.
