Description of Hydraulic electrical contact oil pressure gauge
The primary application of the YX Electric contact pressure gauge
is in the automatic process industry, where it plays a crucial role
in pressure control and alarming. When the measured pressure
reaches the predetermined value, this gauge is capable of
generating signals to facilitate automatic control and alarm
functions. It is specifically designed for measuring pressure in
gases or liquids that are non-corrosive to copper and copper
alloys.
With its built-in overvoltage protection, this gauge offers added
safety and reliability. It does not require oil filling, which
simplifies its operation and maintenance. The gauge features a
novel design and a robust structure, ensuring excellent movement
stability and durability. It can be easily installed and requires
minimal maintenance over time.
Principal of Hydraulic electrical contact oil pressure gauge
The YX Electric contact pressure gauge is comprised of various
components, including a measuring system, indicating devices,
magnetic devices, shell, adjusting device, junction boxes, and
more.
When the pressure being measured comes into contact with the spring
tube, it causes the tube's end to undergo elastic deformation,
resulting in displacement. This displacement is then amplified by
the pointing device and displayed on the dial, indicating the
corresponding pressure value.
The movement of the pointer triggers the instantaneous contact
between the movable contact (upper or lower) and the setting
pointer electric contact means. This contact, in turn, activates or
deactivates the circuit in the control system, enabling automatic
control and alarm transmission.
The electrical contact pins in the contact device are equipped with
adjustable permanent magnets. These magnets enhance contact by
increasing suction force and accelerating contact action. As a
result, reliable contact is achieved, and arc extinction is
ensured. The gauge effectively prevents frequent contact
disconnections caused by vibrations in the working environment or
pressure pulsations in the measured medium. Consequently, the
instrument offers reliable performance, a long lifespan, high
contact switch power, and other notable advantages.
