1. Preliminaries
The torque transducers are made of different shaft materials to suit the loads.
Torque transducers measure torque in the unit Nm.
Please refer to the relevant data sheet for the current technical specifications.

2. Applicability and instructions for use
The torque transducers measure clockwise and counterclockwise loads. In case
of clockwise load, the output signal is positive.
The full-scale value is printed on the device label.
The torque transducers can measure both static and dynamic torques. The low
masses and high torsional stiffness are particularly beneficial in this context.
Please refer to the data sheet for the specified signal rise for the transducer.
The torque transducers need no maintenance as they are fitted with contactless
outputs. Their electrical outputs can be transmitted to remote test benches,
where they can be displayed, recorded, processed and used for control opera-
tions.
The torque transducers are precision devices and should be handled carefully
when transported and when being installed to prevent them being damaged by
shocks or if they fall to the ground. Torque peaks above the rated overload can
severely damage the torsional shaft. These peaks must be intercepted and absor-
bed if they cannot be avoided.
The limits for the permissible mechanical, thermal and electrical stresses are
detailed in the data sheet. They must be strictly observed. Please consider these
limits when designing, installing and operating the measurement setup.
