Description
The 3-component force sensor is mounted under preload between two mounting flanges. The quartz force sensor can therefore measure compression and tensile forces.
The force measurement of the sensor is based on the piezoelectric principle. The application of a force results in the quartz
washers in the sensor (one for each of the force components
to be measured) yielding a charge proportional to the force.
This is picked off by built-in electrodes and transferred to the
corresponding connector.
The contact faces of the sensor are covered with ceramic
discs to facilitate ground-isolated mounting of the sensor. The
straightforward and vibration-resistant design of the sensor
produces a very rigid structure. The resulting high natural frequency makes highly dynamic force measurements possible
over a large frequency range.
The cable connection of the sensors is made via a 3-pole connector V3 neg. (design patented). This is provided with a positioning aid for simple centering that also protects the plug and
receptacle connector against unintended rotation.
After correct mounting the sensor is immediately ready for use
without recalibration.
Application
Kistler 3-component quartz force sensors measure simply, directly and precisely. They are used in the measurement of:
•t t utting forces in metal cutting processes
C
•t t ollision forces in crash tests
C
•t t ecoil forces of rocket motors
R
•t t ibration and friction forces
V
•t t round reaction forces in biomechanics
G
•t t ehicle forces on the road and test bed
V
•t Forces on wind tunnel balances
