GENERAL
DESCRIPTION
CLEVELAND-KIDDER
Type UPB Tension transducers are designed for the measurement and
control of tension on larger web and wire machinery where the guide
rolls are typically mounted on pillow block bearings.
Design parameters are
the result of many years of experience in the field of tension
measurement and control in process machinery. These transducers utilize
a full Wheatstone bridge of semiconductor strain gages. mechanical stops
are provided to limit load displacement to 0.10".
UPB Transducers may be
applied to measure loads both normal to and at any angle up to 45°.
These electro-mechanical Tension Transducers operate in the principle of
strain gages, applied to the tension and compression areas of a beam,
sensing surface deflection under varying load conditions. Semiconductor
strain gages are used to provide a high level, linear output signal.
UPB Transducers are
typically applied in pairs, one under each of the supporting guide roll
pillow bearings. This results in total tension measurement regardless of
web position and differences in edge tensions. the model UPB has been
utilized as a retrofit component and has also been applied as an OEM
component in manufactures systems. They provide the same versatility of
tension measurement, recording and control that is available with
CLEVELAND-KIDDER transducer Types "S", "FL",
"PB" and "BR". See Engineering Data Sheet DS-TRS.
