Product overview
The AI-LE general- purpose submersible level transmitter uses a high-performance diffused silicon pressure sensor as the measuring element . It measures the hydrostatic pressure of the liquid, which is proportional to the liquid depth, and converts it into a standard current or voltage signal output through a signal conditioning circuit to achieve accurate measurement of the liquid depth.
This product is suitable for measuring the liquid level of various media in petrochemical, metallurgical, power, pharmaceutical, water supply and drainage systems and other industries.
