NB 3300 in a dredge application

The Challenge

10 NB 3300 sensors are required in a tank on a dredge ship, which measure the sand sludge level pumped from the seabed with high accuracy. It all has to work while driving. It is a very corrosive environment. The demands on the quality of the sensors are very high.

Our Solution

The solution is the interface sensor Nivobob NB 3000. They work electromechanical with an adjustable feel weight, which is unsensitive to the seawater, but detects the sand slurry. The communication to the visualisation NT 3500 is via Modbus RTU. The sensor is coated and constructed to resist the aggressive environment.
