Water depthThe liquid level sensor adopts high-performance diffusion silicon piezoresistive pressure sensor as the measuring element. After high reliability amplification processing circuit and precision temperature compensation, the gauge pressure or absolute pressure of the measured medium is converted into standard voltage or current signals. This product is compact in size and easy to use and install. It can be directly immersed in water to measure the liquid level height from the end of the transmitter to the liquid level.
