Construction

The Alfa Laval Rotacheck control and validation system for tank cleaning machines consists of a sensor unit with top cover, o-rings and electrical cable and/or connector. The sensor unit has a sensing device located inside the processing tank and is connected to a sensor board, which processes and communicates the signal to the PLC.

Operating principle

The Alfa Laval Rotacheck system is available in two versions with digital sensor output via PNP interface to and from a PLC.

Rotacheck Basic

This standard system is suitable for validating the rotation of the rotary jet head. Ideal for retrofitting of Rotacheck systems that are already installed, Rotacheck Basic registers the moment when the sensor head is hit by the cleaning jet.

• Hit: The moment in time when the water jet hits the sensor head.

• Alarm: In case of unit failure or constant hit (cleaning device error).

• Idle: When the rotary jet head is not in use and cleaning is not being performed.
