Description of electric contact pressure gauge
YX series electric contact pressure gauge is mainly used for
pressure control and alarm in the automation process industry. When
the measured pressure reaches the rated value, it can output signal
for automatic control and alarm. Suitable for measuring the
pressure of gases or liquids that do not contain copper and corrode
copper alloys.
It has the characteristics of overvoltage protection, no oil
filling and no drying. The design is novel, the structure is
reliable, the movement stability is good, and it is durable. Simple
installation and low maintenance

Principal of electric contact 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.
