Calibration and measuring ranges

The expected error deviations of a sensor are directly depen-

dent on the size of the measuring range and the choice of the

operating point. The smaller the measuring range, the better

the linearity and hysteresis.

The piezoelectric force transducers 93x1C are preloaded with

60% of the nominal force of the 90x1C sensor built into them.

This enables the measurement of equally large positive and

negative forces.

The lowest 20% of the nominal force range is not taken into

account, since the susceptibility to moments, shear forces and

non-linearities is highest there.

The load cells 93x1C are calibrated in three different ranges:

+100%, -100%, +1%.

Installation, dimensioning and cabling can be found in the

Mounting Examples, Different Types of Force Introduction

Example A

Example B

Example C

Force introduction of compression forces.

Loading from tensile and compression forces

via an extension piece. The preloading force

on the sleeve must not be less than a mini-

mum value under the effect of tensile forces.

Force introduction of tensile and compres-

sion forces directly onto the threaded con-

nection. In this case, a lock nut should al-

ways be used.

Example D

Mounting example of a force link in a hy-

draulic clamping device. Monitoring of ten-

sile and compression forces.
