SENSiQ Weighbeam WB
APPLICATION
- Ladle turret scale
- Ladle transfer car
- Scrap basket, roller, and tundish scales
- Silo and bin weighers
FUNCTION
- Simple and cost-effective installation through direct bolted joint with the connecting structure without moving parts
- No additional straps or hold down bolts required
- High functional safety and availability, even with frequently unavoidable impact loads and constraining forces
- For maintenance-free scales operated under harsh conditions
CONSTRUCTION
- Compact, flat design
- From WB 50 t: Fit head for form-locking take-up of lateral forces
- Plug connection, also available as hinged plug outlet (WB 40 t – WB 600 t)
- Transfer of high disturbance forces and torques with minimum measuring value interference
- High long-term stability
- High reproducibility
- Separate installation of Weighbeam and connecting cable possible
- Cable change without problems
- Connection dimensions and electrical data are compatible with the earlier design of the weighbeam DWB according to data sheet BV-D2059 and BV-D2058

Cable specification |
The weighbeam has a plug connection.
A separate, shielded cable (Ø 8.5 mm x 15 m) is also supplied with suitable plug socket.
The following applies to the cable: Silicon cable, bend radius: > 40 mm; temperature range: -50 °C …+180 °C |

Requirements of the Quality of both Contact Surfaces
WB 11,5 t … 40 t
WB 50 t … 600 t
▪ Material selection “A”: Construction steel is used of at least S355 grade must be used.
▪ Operating thickness “B”: This depends on the stiffness of the overall construction. The operating thickness of the connect surfaces must be at least 40% of the the weighbeam height.
▪ Surface quality “C”: The average peak-to-valley height required of the contact surfaces is 6.3 μm.
▪ Flatness “D”: The maximum permissible flatness tolerance of each contact surface is 0.05 mm.
▪ Angle error to the vertical axis “E”: The permitted maximum value for the angle deviation of the contact surface to the vertical axis is ± 2° in both planes.
▪ Plane parallelism “F”: The upper and lower contact surfaces to the weighbeam must be plan parallel to each other within at least 0.1 mm.
