Product Description
Single Flange Level Gauge is a new type of transmitter developed by
Xi'an Yunyi using introduced advanced foreign technology and
equipment.Key raw materials, components, and parts are sourced from
imports. The entire unit undergoes strict assembly and testing.
This product features advanced design principles, a complete range
of models and specifications, and simple installation and use. As
the appearance of this model fully incorporates currently popular
domestic design elements, it offers users a fresh and novel
feeling. Simultaneously, it can directly replace traditional series
products in installation, offering strong versatility and
replacement capability.
The measurement principle involves a measuring diaphragm and an
electrode on each of the two insulating plates, forming a
capacitor. When the pressures on the two sides are inconsistent, it
causes the measuring diaphragm to displace. The displacement is
proportional to the pressure difference, thus making the
capacitances on the two sides unequal. Through oscillation and
demodulation stages, this is converted into a signal proportional
to the pressure.
