MCRT®
28000T Series torquemeters are available in capacities from 25 lbf-in
to 4,000,000 lbf-in with overload ratings of 2X full scale. When
installed between a driver and load, the sensor will measure static
and dynamic shaft torque and speed (optional). A strain gaged stainless
steel shaft senses torque and cancels bending and thrust. Robust,
ferrite free rotary transformers connect the gages to noise immune
carrier amplifiers. They don't generate noise or wear, are immune
to magnetic fields, noise, vibration, lubricants and other hostile
environments.
They
are available in either shaft or flanged style configurations. Shaft
end torquemeters are less costly than flanged models and can be
either floated or foot mounted. Flanged models are much shorter
and can be used when axial space is limited or when the highest
shaft stiffness is needed.
Himmelstein's
unique Option G technology that hardens the torquemeter to EMI generated
by IGBT based adjustable speed drives is available as an option.
These
models require strain gage, AC carrier style amplifiers capable
of providing 3 - 6 volts rms at 3 kHz ±10%.
