The
strain of the base material acts through the two contact
surfaces as a change of distance on the transducer. Its
housing serves as an elastic transmission element and
converts the change of sitance into a force. The quartz
disk in the transducer is stressed in shear, generating
an electrical charge Q (pC) proportional to this force
and thus to the strain of the base material. All parts
of the transducer are made of corrosioproof materials.
The "Fischer" connecting plug is self-locking and splashproof.
The strain
transducer is suitable for measuring dynamic and quasistatic stresses on machine components. Its principal application
is indirect force measurement, on presses for example. For this purpose, the transducer is mounted on a part of the machine
whose mechanical stresses is large enough, proportional to the desired measured and as undisturbed as possible. Calibration
is performed after mounting the equipment, by comparative measurement. Special advantages over the familiar strain gauge
methods are high sensitivity, overload security and unlimited life under alternating load.
