Description of Hydraulic electrical contact oil pressure gauge
The YX Electric Contact Pressure Gauge is primarily employed for
pressure control and alarming within the automatic process
industry. When the measured pressure reaches a predetermined value,
this gauge can generate signals to trigger automated control
processes and alarms. It is designed for measuring the pressure of
gases or liquids that are non-corrosive to copper or copper alloys.
Featuring overvoltage protection and the absence of oil filling,
this gauge offers unique characteristics. It boasts a novel design,
a robust structure, excellent movement stability, and durability.
The gauge is known for its straightforward installation process,
requiring minimal maintenance. These attributes collectively make
it a reliable and efficient tool for pressure monitoring and
control applications in industrial settings.
Principal of Hydraulic electrical contact oil pressure gauge
The YX Electric Contact Pressure Gauge comprises several essential
components, including the measuring system, indicating devices,
magnetic devices, shell, adjusting device, junction boxes, and
other integral parts.
When the measured pressure interacts with the spring tube, it
induces a corresponding elastic deformation or displacement at its
end. This displacement is then transmitted and amplified by the
indicating device, ultimately reflecting on the dial through the
pointer. The pointer, in turn, triggers instantaneous contact
(either upper or lower) with a movable contact and a setting
pointer electric contact. This interaction activates the control
system, turning the circuit on or off, thereby enabling automatic
control and alarm transmission.
The electrical contact pins within the contact device handle the
electrical signals. They are equipped with adjustable permanent
magnets that enhance contact suction, accelerating the contact
action for reliable connectivity. This design feature helps prevent
issues like unreliable contacts, arc extinction, and interruptions
caused by vibrations or pressure pulsations in the working
environment or medium. Consequently, the instrument offers reliable
operation, an extended lifespan, high contact switch power, and
other advantageous features.
