Description:
Shelok YK-M3 Electric contact pressure gauge is mainly used for controlling pressure and alarming in automatic processindustry. When measured pressure reaches rated value, it can output signals to operate auto-controlling and alarming.lt is suitable for measuring pressure of gas or liquid that does not copper and corrupt copper alloy.With the over voltage protection, without filling oil does characteristics and so on.Novel design and reliable in structure, good movement stability, durable.Simple installation , small amount otmaintenance.

Principal
It consist of measuring system, indicating devices, magnetic devices ,shell, adjusting device and junction boxesand other components, When the measured pressure contact the spring tube, its end produce the correspondingelastic deformation – displacement, after transmision 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 oncontact, 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 magnetsuction can increase the contact, the contact to accelerate the action, so that access to reliable contact, arc extinctionthe meter can effectively prevent vibrations due to the working environment or medium pressure pulsation caused bvfreguent contacts off. Therefore, the instrument has a reliable action, long life and large, contact switch power andother advantages.
