Force Sensors


Force sensors reliably detect events or changes in the machine environment. Depending upon the variety of machine types and processes, our portfolio contains different sensors with the right characteristics and design to always provide the optimum monitoring solution.


Strain Gauge based Sensors:

Sensors based on strain gauges are suitable for any case which involves any elastic deformation, like torsion or feed force. They achieve an excellent linearity and repeatability and for fixed tooling are available in two variations:

  • FFR (Feed-Force-Ring / Wheatstone) for integration into spindles and feed axis
  • FFP (Feed-Force-Plate / Wheatstone) for integration below turrets,

The sensors signals based on the Wheatstone bridge circuits are connected and adjusted via the 1-Channel Bridge Amplifier BA-01. This combination achieves a high sensitivity for the detection of small force variations.

Another application with strain gauges to reach long-term signal stability and to calibrate force and torque ranges of rotating tools is the DDU rotor.


Piezoelectric Force Sensors:

Piezoelectric sensors are typically used to detect dynamic forces, e.g.collisions. Their application range historically has been wider than that of the strain gauge based sensors.

RS-M10/RS-M12/RS-M16: these ring-shaped force sensor with integrated charge amplifier. Those are typically fitted under M10, M12, or M16 screws directly to the turret or the spindle

CFW: force sensor similar to the RS-series, but without integrated charge amplifier. In this case a digital charge amplifier needs to be connected: CMD-600 (IP65)

Further piezoelectric force sensors:

  • AKS-1 / AKS-3: force sensors with one, two or three force measuring axes are typically applied between machine elements turret + slide. A charge amplifier is integrated
  • ADS-31: a sensor for measuring the surface tension of metal constructions. This sensor needs to be connected to a measuring transducer (CFM-4 or FM-01)

All force sensors are suitable for CTM (with transducer CFM-4) and Genior Modular (with transducer FM-01) Process Monitoring Systems.
