NB 4200 in casting sand storage
The customer required a content monitoring system to monitor the reclaimed and new sand with their process silos in a small foundry in the north of England. They had experienced problems with running out of sand on a number of occasions causing the plant to shut down. The foundry had a strict health and safety procedure and would not allow workers to climb to the top of the silos daily to manually measure the levels.
The NivoBob NB 4200 was fitted to each silo and the output feed sent to panel with basic 4 digit 4-20mA displays. They were able to manually start the NivoBobs from the panel and keep a record of each silos contents. The NB 4200 successfully saved the customer time and money as they haven't run out of sand since the NivoBobs were fitted.
