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. |
| |
|
 |
Low profile cells (LPC)
can be used in compression and tension.
Robust tool steel construction.
Full range of mounting accessories available (see

|
|
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. hoppper scales, roller
converyor 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. |

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. |
