The installation of this subminiature
load cell needs to be done with caution and due
diligence. These must be mounted on a flat and even
surface by means of a contact glue, wax or a small
laminated spring holding down the sensor body.
Pre-strain forces that may influence the sensor output
directly must be avoided as well as clamping the sensor
on its sheath.
The force to be measured shall be inserted centrically
and free of lateral forces. The latter must be
neutralized by lever or mechanical guides. The mounting
must always be done manually without the use of driven
tools. Damages by overload during the mounting process
can be avoided by connecting the sensor electrically and
indicating the force value simultaneously.

| Description |
 |
The subminiature load cells are flat,
cylindrical discs with covered bottoms. The load
insertion button for adapting compression forces is
integrated part of the upper side which resembles the
membrane of the sensor body. The strain gauges are
applied on the interior side of it, wired to a
Wheatstone bridge. The result is a voltage output
proportional to the load applied.
The connecting cable of the load cell features a covered
correction network on a small board. The temperature
compensation is installed therein.
Due to its extremely small dimensions, this model is
predestined for use in applications with limited space.
The small diameters result in high frequencies of
resonance.
