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.
