Split input type liquid level transmitter display water level sensor integrated static pressure level gauge 4-20MA

The input (hydraulic) type liquid level transmitter adopts a high-performance diffused silicon piezoresistive pressure sensor as the measuring element. After a high-reliability amplification processing circuit and precise temperature compensation, the gauge pressure or absolute pressure of the measured medium is converted into Standard voltage or current signal. This product is small in size and easy to use and install. It can measure the height of the liquid level from the end of the transmitter to the liquid surface directly by putting it in the water.

       Features
