SENSO 3000
The hydraulic clamping technology is a well-known, proven and reliable method for the clamping of tools. Thanks to its
completely closed design the system is sealed and impervious, requires extremely low maintenance and guarantees
longevity. Following many years of general use, however, thermal and mechanical influences can lead to a reduction in
clamping force. The result can be a poor tool life and a diminished surface quality including expensive tool breakages
during machining operations.
Determining the loss of clamping force was until now extremely costly and inaccurate. It involved either determining the
number of clamping screw rotations or the torque with the assistance of a proofing bar and a torque key or the expansion
rate applying an accurate internal measuring instrument.
The new Guhring SENSO 3000 measuring instrument offers a precise, quick and simple as well as consistent method of
measuring the clamping force. An added advantage is the mobility of the system, i.e. for measuring within machines and
fixtures.
SENSO 3000 determines the clamping force of the hydraulic chuck via a pressure sensitive plug gauge. The entire length
of the plug gauge is clamped in the hydraulic chuck so that when tightening the clamping screw the clamping pressure
of the chuck is optimally applied. The clamping force measuring instrument displays the clamping force as an absolute
measurement value on the one hand and as a percentage clamping force in relation to a reference value that can be set
individually on the other. This way, SENSO 3000 can be adapted to customer specific application conditions and require-
ments.
The clamping force measuring instrument is supplied with a plug gauge for the respective clamping diameter as well as a
carbide proofing bar for calibration purposes and a CR 2430 type battery – all in a sturdy and handy case.

orce of HSK clamping systems and of hydraulic chucks.
Clamping force measuring instrument, Guhring no. 4974
The accuracy of a HSK connection not only depends on the geometry of the connection, also the drawing force of the
HSK clamping systems considerably determines a powerful and accurate connection. In order to ensure operational relia-
bility it is advised to inspect the clamping force of the HSK interface on a regular basis.
For this, Guhring provides a fully mechanized clamping force measuring instrument. Its function principle is based on a
linear length deformation of components that is proportional to the force. A force is allocated to the length deformation
and displayed by an analogue dial gauge.
