Piezoelectric force sensors, also known as piezoelectric ring

force transducers, for precise measurement of tensile and com-

pressive forces in highest resolution.

The force sensors are thoroughly tested, but are delivered wit-

hout calibration certificate and must be calibrated on site after

installation.

• Thoroughly tested, delivered without calibration certificate

• Linearity including hysteresis ≤±1.5%

• Extremely high stiffness

• Very compact design

• Extremely low threshold

• Degree of protection: IP68, dependent on cable

• Operating temperature range -40 ... 120°C

• No aging, unlimited service life

Description

The 910x family is a piezoelectric (PE) sensor series for force

measurement in the z-direction. The force to be measured is

transmitted directly to the quartz element located within the

sensor. When subjected to a mechanical load, quartz produces

an electric charge that is proportional to that load. An outstan-

ding property of quartz is the very low threshold, resulting in a

high sensor sensitivity which is extremely linear over the entire

measuring range. Thus the behaviour in a certain measuring

range is practically identical for all PE sensors, independent of

their size.

This has three unique advantages:

• Overload protection:

Even very small forces can be measured

with a sensor with a large measuring range, so that overload

protection can be considered without loss of signal quality.

• High stiffness:

To achieve a construction that is as stiff as

possible, a larger sensor can also be used without negatively

impacting the quality of the measurement signal.

• Grouping:

Multiple sensors can simply be added together

by electrically connecting them in parallel to a single charge

amplifier. The output voltage is then proportional to the sum

of all acting forces.

Application

For monitoring tasks, force sensors are required that can be

easily installed in a machine structure. Robust design and re-

liability in continuous operation as well as good repeatability

of the measured values are further features of these sensors.

The choice of a certain size depends on the installation space

available on the one hand and on the force shunt ratio of the

installation on the other hand.

Application examples

• Monitoring of press-in forces during assembly, testing, etc.

• Monitoring of forces during punching and forming

• Measurement of large forces in force shunt

Sensor Mounting

Ring force transducers are generally used preloaded in a

mounting structure.
