Description
Tank Weighing
The RLC load cell with capacity range from 250 kg to 10 t, allows the weighing of mid sized tanks, vessel and hoppers. The stainless steel design, hermetic sealing and IP68 protection provides the best reliability in tank weighing applications.
Sanitary Application
The stainless steel housing is welded in place to create a hermetic seal to prevent moisture from entering the interior of the load cell. This prevents deterioration of performance and subsequent failures.
0970 RingMount
The optional METTLER TOLEDO 0970 RingMount weigh module adds suspension, checking and anti-tipping to your RLC load cell and includes top and bottom mounting plates to simplify installation. Available in 316 stainless steel.
