Overview

HPM412 submersible level transmitter features a fully sealed, submerged design and utilizes a high-quality, highly stable pressure sensor as its sensing element. The built-in pressure sensor has no sealing ring and is fully welded to the housing, significantly reducing the risk of leakage. Furthermore, multiple layers of reliable sealing are incorporated into the connections of the housing, cables, and other components. Internal potting ensures a long service life. The top threaded connection allows for easy installation and mounting in ship compartments, containers, and other similar locations.

This product is widely used in various applications in the marine industry, including pressure and level monitoring in ship compartments, level measurement in various containers, water treatment, and industrial process control.
