If you need to be more than 100% safe and want to avoid overfilling your launders at any cost, the OFG (Over FIll Guard) can be installed as an additional protection and failsafe redundancy.
Prevent over-filling situation
Helps avoid security risks with over-filling launders
Neat design to fit mounting on brackets and hang above metal levels
The sensor has a built-in safety circuit and can easily be mounted on the outside of the launder
Automatic tilting function
Optional to add an automatic tilting function
Extended security for any casting
The OFG-285 consists of a main unit with a safety circuit and a swing arm conduit to an electrode head. The main box can be mounted to brackets 50 mm (2”) outside a launder. The electrode head is to be swung over the molten metal and leveled so that the ends of the electrodes hit just above the maximum allowed level in the launder. The electrode head can be swung out from the launder during maintenance.
