Blum-Novotest cold-heat test stand for drive shafts in complete view


The hot/cold test stand for bellows checks up to four drive shafts and therefore eight bellows simultaneously. Every bellow is monitored for grease leakage and wear, although only the affected line is switched off in the event of damage.

NovoPS Test Stand Software

The NovoPS test stand software is a Windows-based solution that is programmed in-house and optimised for the respective test task. As the interface to the user, the uncomplicated user interface provides intuitive access to all functions of the test stand. Moreover, both the connection of the test stand to the customer's conveyor systems as well as its integration into the existing network environment is taken into account. This enables the data acquired to be processed and evaluated independently of the test stand.
