Product Description
product overview
The AO920W ceramic capacitive liquid level transmitter adopts a ceramic capacitive sensor. It uses dry pressure measurement technology without an intermediate liquid, giving full play to the technical advantages of the ceramic sensor and endowing the pressure transmitter with excellent technical performance. It has strong overload and impact resistance, high stability, and high measurement accuracy. The AO920W ceramic capacitive liquid level transmitter is available in a variety of models, ranges, process connection forms, and materials. It can be widely used in many industrial fields such as petroleum, chemical, electric power, metallurgy, pharmacy, and food. It can adapt to various industrial measurement occasions and media. It is an ideal upgrade product for traditional pressure gauges and traditional pressure transmitters, and is a pressure measurement instrument in the field of industrial automation.
