Just 32mm high but with a
measuring range of ±10kN, Kistler
Instruments’ Type 9129AA three
component dynamometer is suitable
for measuring the machining forces
involved in drilling, grinding, milling
and turning operations as well as
general, multicomponent force
measurement in confined spaces.

The materials used in the
construction of the dynamometer
are resistant to corrosion by cutting
fluids and the unit is sealed to IP67
when used with the matching cable.

The design uses four multicomponent,
piezoelectric, force
sensors, which provide the three
components of the force vector and
the three components of the
resultant moment vector. Forces are
measured with almost no
displacement and the design
minimises temperature error.
