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, ±200 N-m and ±1,000
N-m.
•Two calibrated measuring ranges: 100%, 10%
• Very compact, ready to install reaction torque
sensor
• Flexible adaptation with mounting threads in double flange
• Centering seats for coaxial mounting and optimum
introduction of torque
• Centric bore for shaft passage
• Can be used as torque calibration sensor
Description
The reaction torque sensor is integrated under high
preload between preload screw and nut. When a torque
acts on a sensor, 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.
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.
Kistler reaction torque sensors reliably detect even
the slightest torques acting on the sensor axis in both
rotary directions.
