Compression Load Cells
These Compact Ring – Torsion Load Cells provide high accuracy even for very small utilization ranges. The high output signal provides a high resolution of useful signal range. The design is sturdy with minimal effect on accuracy by side forces. These cells will operate under very harsh environmental conditions. Several mounting structures are available to suit most applications.

SPECIFICATIONS & DIMENSIONS

Elastomer Mounts for Compression Cells
- Self-centering capability
- Dynamic load damping properties
- Minimal reaction to side forces
- Simple, rugged and flat design
- High resistance to environmental influences and chemicals
- Insensitivity to inclined position of connecting structure up to 0.6° = 10 mm/m
- Legal-for-trade
- Easy installation
- Maintenance- free
Application
The elastomer mounts are designed for load input to the Schenck ring-torsion load cells optimized with regard to measurement.
They are used with all kinds of industrial weighing systems, e.g. hopper scales, roller conveyor scales, crane scales, road weighbridges. |
Construction
The elastomer mounts consist of the contact plate for load input, the elastomer for self-centering, and a base plate for load output to the supporting structure.
Lateral play must be limited depending on the installation situation. Lifting off has to be prevented by using appropriate hold-downs. |
Functions
The weight to be measured is applied to the load cell via a contact plate. Due to the special design, the vertical deflection is extremely low and proportional to the load.
Occurring side forces deform the elastomer in a parallel direction. the mount centers automatically when relieved of side force.
Depending on the admissible area pressure of the load receptor, it may be necessary to install a load distribution plate over the contact plate. This requires to be checked when changing from steel to concrete.

Compact Mounts for Compression Cells
- Complete compact mount with integrated bumber check and hold-down
- Legal-for-trade
- Simple, rugged and flat design
- Dynamic load damping properties
- Insensivity to inclined position of the connecting structure up to 0.6° = 10mm/m
- High resistance to environmental influences and chemicals
- Maintenance Free
- Roughly aligned in factory
Application
The compact mounts are designed for load input to Schenck ring-torsion load cells optimized with regard to the measurement.
They are used as a mounting unit with integrated bumper check and hold-down in all kinds of industrial scales, e.g. hopper and silo scales, container and mixer scales. |
Construction
The compact mount consists of the load input section, the bumper check, and the hold-down.
Positioning of the compact mount is realized by shifting it in the receiving structure.
The play of the bumper check and the hold-down can be adjusted with set screws.
Play can easily be set and checked even if the local situation is tight.
The height is adapted by using shims (max. 5 mm). For fixing the mount, it is either screwed or fastened to the structure. |
Functions
The weight to be measured is applied to the load cells via a contact plate. Due to the special design, the vertical deflection is extremely low and proportional to the load. Occurring side forces deform the elastomer in a parallel direction. The mount centers automatically when relieved of these side forces.
The bumper check limits the play, the hold-down prevents lift-off. A tie rod is not required. |
Pendulum Mount for Compression Cells
- Mount for compact load cells RTN
- Suitable for highest accuracies
- Legal-for-trade
- Extremely rugged (stainless steel)
- Self-aligning
- Easy installation, maintenance free
Application
Pendulum mounts VPN are specially designed for use with compact load cells of the RTN type. They are used where long life and highest measuring accuracy are required in severe environments.
Typical applications are road weighbridges and hopper scales. |
Construction
A complete VPN self-aligning mount consists of the pendulum contact plate, a pressure plate, the centering piece and height adjustment shims. The load cell can be mounted on supporting structures or on an optional foot plate. On rough ground, the foot plate provides optimum mounting surface. |
Functions
The weight force to be measured is applied to the pendulum contact plate via the pressure plate down to the load cell. The pendulum contact plate protects the load cell from interfering lateral forces. The self-aligning function of this mount automatically returns the scale to its resting position after deflection. Depending on the local situation, the scale has to be equipped with movement limit stops. |
