Capacitive liquid level sensor
Principle
Input type (Hydraulic pressure) liquid level transmitter adopt high performance diffused silicon piezoresistive pressure sensor as measuring element, after the high reliability of amplification circuit and precise temperature compensation, convert the gauge pressure or absolute pressure of the measured medium into standard voltage or current signals.
This product has the advantages of small volume, convenient use and installation,directly put into the water, that can measure liquid height from the surface to the end of the liquid level transmitter.
