Features of High quality electric contact vacuum pressure gauge
It consist of measuring system, indicating devices, magnetic devices ,shell, adjusting device and junction boxes and other components. When the measured pressure contact the spring tube, its end produce the corresponding elastic deformation – displacement, after transmission amplification by the pointing device is indicated on the dial. The pointer drive instantaneous contact (upper or lower) movable contact and setting pointer electric contact means on contact, causes the control system turned on or off the circuit, in order to achieve automatic control and alarm transmission.
Electrical contact pins in the electrical signal of the contact device, provided with adjustable permanent magnet, suction can increase the contact, the contact to accelerate the action, so that access to reliable contact, arc extinction, the meter can effectively prevent vibrations due to the working environment or medium pressure pulsation caused by frequent contacts off. Therefore, the instrument has a reliable action, long life and large, contact switch power and other advantages.
Applications of High quality electric contact vacuum pressure gauge
Extensive use of supporting the petroleum, chemical, power plants, metallurgical and other industrial enterprises and electrical and mechanical equipment.
