–1 … 1 N·m up to –1 000 … 1 000 N·m
These easy to install piezoelectric reaction torque sensors are
particularly suitable for measuring rapidly changing torques at
non-rotating shafts. Five different size sensors are available for
the measuring ranges ±1 N·m, ±10 N·m, ±25 N·m, ±200 N·m
and ±1 000 N·m.

Description
The reaction torque sensor is integrated under high preload between preload screw and nut. When a torque acts on a s­ ensor,
the shear stresses produced are transmitted to the c­rystals.
The charge signal proportional to the force is picked up by an
electrode and fed through a screened cable to a charge amplifier. The charge signal is converted by the charge amplifier
to a proportional output voltage, which can be ­recorded and
evaluated.
9329A_000-463e-08.13
Flanges on the top and bottom sides of the reaction torque
sensor allow simple and direct installation on a shaft or adapter
flange. This allows very low, space-saving installation. Alternatively, a mounting flange (optional accessories) can be used or
installation can take place using custom adapters. A two-sided
centering facility allows very accurate coaxial fitting. A centric
bore allows additional applications, e.g. for shaft bushing. A
screw-on connector cover ferrule is provided with the included
accessories to protect the cable connection at the side.
Application
The sensor is suitable for measuring a dynamic or quasistatic
torque acting on the sensor axis.
Examples of Application
• Torque setting of pneumatic screwdrivers
• Testing screw connections
• Calibration of manual torque wrenches
• Torque testing of springs
• Measurements on friction clutches
• Measurement of starting torques on electric motors
• Measurement of irregular rotation and torsional vibrations
on small servo and stepper motors
• Testing of rotary switches (product testing)
Kistler reaction torque sensors reliably detect even the slightest
torques acting on the sensor axis in both rotary directions.

General
The torque should be introduced by the smallest possible
­eccentricity of the axes to be connected (<0,02 mm). Bending moment and shear forces should be avoided as far as
­possible.
The surfaces contacting the reaction torque sensor must be
flat, rigid and clean. The centering facility on both sides of the
reaction torque sensor using centering rings (included accessories) allow very accurate coaxial fitting.
The sensor can be fitted directly via the integral flanges on two
sides. Special adapters can be manufactured for adaptation to
the customer's specific applications.
