Version 5.0 of Coperion‘s Rotorcheck contact monitoring system for rotary valves comes with physical separation of measured value logging and evaluation electronics, and redeveloped control system. Furthermore, the use of high-quality components contributes to longer uninterrupted running times. The monitoring principle of the Rotorcheck
remains unchanged: An electrically conductive connection is created as soon as the housing and rotor come into contact. This is then registered by the control system. In the process, the software filters out coincidental measurement signal fluctuations – such as those caused by the product – and reports potentially dangerous faults to the customer’s control center.
While the signal detection itself takes place in the valve, Version 5.0 allows for the snap-in installation of the control system housing in the control cabinet. The physical separation reduces the amount of space required on the valve while simultaneously simplifying the operation and maintenance of valves with an extraction device. What’s more, the control system is now also accessible even when it is impossible to enter the production area itself for safety reasons, e. g. while CIP cleaning is underway. Rotorcheck 5.0 is suitable for deployment in Ex zones in combination with optional Zener
barriers.
