Overview
The AVKP92 liquid level transmitter consists of a high-performance diffusion silicon piezoresistive pressure sensor as the measuring element, which accurately measures the static pressure of the liquid proportional to the depth of the liquid level. The internal dedicated integrated circuit converts the sensor millivolt signal into a standard (current or voltage) signal output, establishing a linear correspondence between the output signal and the depth of the liquid, and achieving measurement of the depth of the liquid. The product has high accuracy and small size. It can be directly put into the liquid to measure the liquid height from the end of the transmitter to the liquid level, making it convenient to use. Suitable for liquid level measurement and control in the fields of petroleum, chemical engineering, power plants, urban water supply, and hydrological exploration.
