The miniature ring
load cell of the 8438 series have been
specially designed to have small external
dimensions. Small diameters and low
assembly heights make these units
suitable for installation in structures
where the measured force is routed
directly through the sensor after
separation. Examples of this are force
measurements on
|
bolts, |
|
screws, |
|
plate and cover
fastenings, |
|
bearing contacts, |
|
spot welding machines, |
|
cutting tools. |

| Description |
 |
The
measured force must be introduced via the inner and
outer bands of the sensor respectively. For example,
when the outer band is the contact surface, the
measured force is introduced via the part attached to
the inner band. The conversion of the acting force
into an electrical output signal is performed by
strain gages connected together in a full bridge
circuit. To achieve optimal accuracy, the base of the
sensor should rest on a smooth level surface, hardened
to min. 63 HRC with sufficient dimensions.
Lateral forces should be avoided, as they distort the
measured results.
During installation, ensure that the cable outlet and
the sensor cable are not subjected to excessively high
tensile or bending forces.
