| The
Series 9300 Torsionometer is ideal for measuring torque on machinery
where little down time can be afforded. The quick installation of
the clamp-on collars with the pre-calibrated bending beam converts
I/O shafts into instant torque transducers. The 9300 Series are ideal
for those applications involving repetitive testing of identical systems.
The clamp-on 9300
Series uses a pre-calibrated bending beam which is clamped at each
end by a counterbalanced collar around a heavy-wall or solid shaft
to sense torque. The torque generated between the collars is dependant
on the shaft diameter, RPM, and the distance between the collars.
Each installation uses one of a selection of bending beam lengths
to generate the specific output to the on-board RF transmitter.
The RF telemetry
package is induction-powered by a stationary loop antenna coupled
to a power supply and receiver. The on-board telemetry concept eliminates
the need for support bearings and slip rings. The clamp-on feature
allows an installation without modifying the shaft surface.
A variety of collars
and bending beams are available to accommodate high torque ranges
and shafts from 2.5" to 32" in diameter. Running speeds are from 2500
rpm down to zero rpm. The system is insensitive to shaft speed variations,
and full accuracy is obtained down to zero RPM. The built-in transmitter
may be environmentally sealed for harsh environments and high vibration.
In determining
if the 9300 Series will work in your application, we have to consider
the relative micro strain in your shaft. We will need the following
information:
- Outside diameter
- Inside diameter
(if hollow)
- Torque in in-lbs
applied to your shaft. If you do not know the torque value, but
you do know Horsepower and the RPM, then calculate: Torque= 63025(horsepower)/RPM
- Shaft material
- The installation
environment
When you are considering
an application for the 9300 Series, call the factory because installation
details may vary with application. When calling the factory, please
have the above data available for discussion.
