Piezoelectric force sensors, also known as piezoelectric ring force

transducers, with extremely flat design for precisely measuring

compression forces. Maximum resolution capacity, high stiffness

and extremely compact dimensions enable ideal installation in

mechanical structures. The case is hermetically sealed and has an

integrated, splash-proof connecting cable with connector.

The piezoelectric force sensors SlimLine are supplied uncalibrated

and must be calibrated in situ after mounting for absolute mea-

surements.

• Extremely small size with large measuring range

• Flexible mounting in force shunt mode

• Also suitable for tensile forces when preloaded

• Measures practically free of displacement, wear and fatigue

• Measures even small forces with high resolution

• Sealed housing (IP65)

• Integrated, non-detachable cable with fluoroelastomer sheath

Description

The force Fz to be measured acts on the sensor via the preloaded

or mounting structure and produces a charge that is directly propor-

tional to the force. This is measured by an electrode and fed to the

charge amplifier via the integrated cable.

1) The preloading force is to be adjusted according to the desired tensile/compression force

range. The measuring range is thereby reduced proportionately

2) Applies with recommended preload

3) The IP degree of protection acc. to EN60529 is determined with water. Oils, emulsions,

cooling lubricants, etc., usually have a better wetting and penetration capacity. The degree

of protection in contact with such liquids is to be classified lower accordingly.

Technical data

To meet the specifications, the sensors must be operated and counterchecked with 20% preload.

Application

Because of their exceptional stiffness, SlimLine sensors are especially

well suited for measuring dynamic forces. Cyclic measurements or

measurements over several minutes are also possible, however.

The sensor is especially well suited for measuring forces in shunt

mode (Fig. 4). This means that the sensor is embedded and

preloaded in a structure. As a result, it is loaded with only part of

the process force.

Its especially small size is ideally suited for installation in structures

such as force plates, fitting strips and tools. The sensor is used in

industrial production processes in which forces are monitored or

measured. Used in combination with a ControlMonitor, the sensor

is ideal for quality control and monitoring.
