What Is the NAGANO KEIKI KE22 Pressure Transmitter?

The KE22 is a precision pressure measuring instrument designed to detect liquid or gas pressure and convert it into a signal suitable for monitoring systems.

In marine applications, the transmitter measures hydrostatic pressure generated by liquid columns inside tanks. The automation system then converts this pressure into accurate tank level information.

This allows engineers and bridge personnel to monitor:

• Ballast Tank Levels
• Fuel Oil Tank Levels
• Fresh Water Tanks
• Cargo Tanks
• Bilge Tanks
• Service Tanks
• Draft Measurement Systems

The transmitter continuously sends real-time measurement data to control and monitoring systems.
