Model 2121-2126 - Honeywell Test and Measurement Sensors

Model 2121-2126
Shaft Reaction Torque Sensor
DESCRIPTION
Model 2121-2126 shaft reaction torque sensor is designed for
strain gages on a special machined portion of the transducer to
installation between test pieces such as motors, switches, axles,
achieve a maximum non-linearity of 0.1% over a wide dynamic
or shafts and their mounting plate. These models operate and
range. Typical applications include tire braking, motor dyna-
are calibrated in both directions. Nickel-plated alloy steel con-
mometers, friction-skid testing, and twist measurement. 100 in-lb
struction enhances durability in harsh, industrial environments.
to 500K in-lb capacities.
These models have no moving parts and utilize four bonded
FEATURES
•
100 in-lb to 500K in-lb capacities
•
0.1 % non-linearity and hysteresis
•
No maintenance of slip rings, bearings, or brushes
•
Reduced friction error
•
Low-end sensitivity
•
Reaction measurements eliminate speed limitations
Safety considerations: It would be unsafe to operate Honeywell torque sensors and
load cells beyond static overload or ultimate extraneous load limits as defined in
the glossary of terms or, when applicable, higher than maximum speed. When in
doubt, consult factory. Honeywell is not responsible for any property damage or
personal injury which may result because of the misapplication of the transducer.
