How do you address unknown issues such as "start-up torque" and
"unknown torque transient spikes.“?
Is a safety factor sufficient to address these problems?

When designing a rotary torque transducer into an application, do
you think the pedestal-mount or the general purpose rotary torque
transducer is the best approach?
Ken
I usually recommend shrink disk couplings over keyed couplings.
Is this the right thing to do?

What is the best way to measure shear (lateral) forces appliedto a flat plate that is used to
measure vertical force(e.g. weight)?

How can you tell the direction of rotation from the output voltage?

How would you go about minimizing slippage at the mounting locations
for torque cells that measure in both directions?

Are there sensors available that can measure both
applied load andtorque simultaneously?

Why does the metrology community, specific to torque measurement,
not properly estimate the associateduncertainty with the measurement
being made?

What adaptors do you use to hold the torque wheel to the
transducer centerline?On some transducers the centering square pocket that accepts
the adaptor are not perfectly square leaving side to side movement of the adaptor and torque wheel. This does seem to
make a big difference on torque below 250“ lbs. The square pockets are not always square or the same size.
What can I do to reduce my uncertainty and how do you correct
these issues?

Do you add repeatability of a torque wrench to your MUA budget?
If so, how many measurements are made? Do you do repeatability at each calibration point? If repeatability is made would you repeat the test point multiple times and move on to the next test point or go through all test point and then repeat?
Do you add resolution of the torque wrench to your MUA budget? If so, what resolution do you use for a non reading, settable type torque wrench? If the resolution and repeatability are included in
the MUA budget, how is an adequate TUR ie 4:1 maintained when conformance testing? Do you take multiple readings and verify all readings are within specs? How often do you calibrate
the Moment arm that is used to calibrate torque cells?

What are the largest contributors in an uncertainty for a torque calibration?

Aside from a more compact format is there any reason to use
a torque transducer over aload-cell at a known offset?

Measurement of torqueon a 8" driveshaft is needed. High resolution (to accurately measure torque under no-load conditions) to a maximum of 24000 ft.lbs (4000 ft-lbs engine torque reduced 6:1) is needed. The sensor is also for field use (no slip rings and
IP67 sealing) and re-usable.
Do you have any suitable torque sensors for this application?

We are looking for a facility to perform torque measurement on
fastener over 1" diameter. Coefficient of friction using
Ni-ease vs. Copaslip vs Loctite.Can you advise?
Lana
Is there any protection in case the test torque goes over the
expected capacity?
