General description, field of application
Mechanical power transmission through rotating machine parts often requires
extensive investigations of machine parts that transmit or generate power.
Furthermore, continuous monitoring is often required. This, in turn, makes it
necessary to have transducers to sense the physical quantities torque and
speed of rotation.
The torque transducers type T32 FNA from HBM which are without sliprings
and bearings, provide torque sensing as well as speed measurement. The
torque transducers are suitable to determine static as well as dynamic torque
in stationary and rotating shafts. Speed of rotation can be determined as well
as the sense of rotation. The multiplication of both factors gives the shaft
power.
Torque transducers are available for nominal torque ratings from 50 Nm up to
25 kNm. The maximum speed rating is 20000 min

, depending on the ac-
tual type.
A frequency modulation system with non-contacting, inductive transfer of the
signal and the excitation voltage provides a system for the sensing of static
and dynamic torque which is free from wear and maintenance.
Owing to the bearing-free design preventive maintenance and lubrication is
not required. Friction losses and heating will not occur.
The field of use of the T32 FNA is to measure the required power or the effi-
ciency, or applications on process control as well as continuous monitoring of
machines.
