Industry Information
Electric contact pressure gauge is used for pressure of various non-crystalline liquid gas and other media
2012-3-3 9:54:00

适用于测量对铜合金无腐蚀、无爆炸危险、非结晶的各种液体、气体等介质的压力。 The electric contact pressure gauge is suitable for measuring the pressure of various liquids, gases and other mediums which have no corrosion, no explosion hazard, and are non-crystalline to copper alloys. The meter can be used with the corresponding electrical components to achieve the two-position automatic control and signal (alarm) for the maximum or minimum pressure value actually set in the pressure system under test. It consists of a measurement system, an indicating device, a magnetically assisted electrical contact device, a housing, an adjustment device, and a junction box. When the measured pressure acts on the spring, the corresponding end of the spring produces a corresponding elastic deformation-displacement, which is amplified by the transmission mechanism and then indicated by the indicating device on the dial. At the same time, when the pointer drives the movable contact of the electrical contact device to contact the contact (upper or lower limit) on the set pointer, the control system turns on or off the circuit to achieve the purpose of automatic control and signal alarm. The electric contact signal pin of the electric contact device is equipped with an adjustable permanent magnetic steel, which can increase the contact suction and speed up the contact action, thereby making the contact reliable, eliminating the arc, and effectively avoiding the instrument due to the working environment vibration or medium. Pressure pulsations cause frequent contact closures. Therefore, the meter has the advantages of reliable operation, long service life, and large contact switch power. Electrical parameter and control form of contact device. Maximum working voltage of contact power


Magnetically assisted electrical contact pressure gauges are widely used in petroleum, chemical, metallurgical, 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. Generally, the instrument can be used with corresponding electrical components (such as relays and contactors) to measure (control) the pressure system. HAKK-YXC series magnetically assisted electrical contact pressure gauges are widely used in petroleum, chemical, metallurgy, power stations Measure the pressure of various fluid media without explosion danger in other industrial departments or in the supporting of electromechanical equipment. Generally, the instrument can be used with corresponding electrical components (such as relays and contactors, etc.) to achieve the purpose of automatic control and signaling (alarm) for the pressure system under test (control). In order to meet the different needs and needs of the test object, a series of more than 10 types of products have been developed, including corrosion-resistant, anti-vibration, and isolation devices. In view of the fact that this series of meters not only have the characteristics of novel design, reliable structure, complete variety and specifications, good motion stability, and strong adaptability, but also have the advantages of measurement and control, simple installation, and small maintenance, so it is generally no instructions 4. Unmatched pressure measurement and control instruments for pressure controllers without switching difference adjustment and external setting devices. By filling the body with oil and using liquid damping to ensure a vibration-free display, it is suitable for measuring places with strong pulsations of media and large environmental vibrations.

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.
