Online Tension Measuring Systems
Measuring principle:
3-Roller Measuring System: Consisting of two outer guide rollers and a middle measuring roller. The tension of the measured material slightly deflects the measuring roller. This deflection (up to 0.5 mm) is measured by a load cell. The built-in amplifier then generates an analog output signal which is proportional to the measured tension.
1-Roller Tension System: In combination with 2 outer reference guiding points the sensor builds a force triangle. The angle of contact has to be stable. The sensor uses straingauges and supplies a output signal in mV or V (with integrated amplifier).

SCHMIDT Online-sensors and display units:
For the continuous measurement of the running line tensions of threads and yarns, wires, cables, optic and carbon fibers and similar materials, SCHMIDT offers a wide variety of sensors using different guide rollers and frontplate dimensions.
Please contact our technical depart-
ment to discuss your applications!
Depending on the application, SCHMIDT Online Tension Sensors can be supplied alone or as a part of a complete system:
I. Tension sensor 3-Roller Sensor only
+ for use with customer supplied closed loop control units
+ for use with customer supplied display units
+ for use with customer supplied regulated DC power source
Customer signal processing: For example closed loop control
