Electric contact pressure gauge uses YX, YXC-60.100. 150 electric contact pressure gauge, magnetic aid type electric contact pressure gauge, by ordinary pressure gauge and contact device two d.u vertical part. Stable and reliable work, widely used to measure the corrosion of copper, steel and alloy of liquid, gas and other media pressure and signal, for automatic control system, through the control circuit, to achieve the purpose of automatic control alarm. In the electric contact signal needle of the electric contact pressure gauge device, equipped with adjustable long-term magnetic steel, can increase the contact suction, speed up the contact action, so as to make contact reliable, eliminate the arc, can effectively avoid the instrument due to the vibration of the working environment or medium pressure pulsation caused by frequent contact off. Therefore, the electric contact pressure gauge has the advantages of reliable action, long service life and larger power of the contact switch. The function principle of electric contact pressure gauge is that the spring tube of the measuring system is under the pressure of the measured medium, forcing the end of the spring tube to produce the corresponding elastic deformation - displacement, with the help of the tie rod through the gear drive mechanism transmission and amplification, the pointer fixed on the gear shaft (together with the contact) will be measured on the dial to point out. At the same time, when the contact on the given needle (lower limit or upper limit) contact (or disconnect) instantaneous, through the relay and contactor in the circuit system (power on or off), so that the control mechanism to make the corresponding action (work or not), and can send electrical signals, in order to achieve the purpose of white motion control and alarm. Technical specifications of electric contact pressure gauge Accuracy class: on 1.6%F·S off 4%F·S Set point deviation :±0.5~4% Switching difference :±1~3.5% Control mode: upper limit and lower limit contact power: 10VA.30VA z.u High working voltage :DC220V or AC380V Ambient temperature: -40~ 70℃

Electric contact pressure gauge product selection

Electric contact pressure gauge installation and use
1. The electric contact pressure gauge should be installed in an environment where the ambient temperature is -40 ° C to 70 ° C and the relative humidity is less than 80%.
2. Before use, check whether the working condition of the contact is normal, whether the contact force exceeds the rated value, and whether the connection is correct (see the attached drawing).
3. The distance between the installation position of the electric contact pressure gauge and the measuring point should not exceed 10M, otherwise the accuracy of the meter reading will be affected by the pressure loss along the way.
4. The instrument should be installed vertically. When the installation place is far away from the measuring point, it should strive to keep level with the measuring point.

Note: The working voltage is recommended to be less than 36V, but not less than 12V, so as not to cause unreliability of contact.
