Abstract
A beam force measuring system having a force sensor to be mounted to each beam of a cyclically operating machine between a force diverting part and a fastener which secures the beam. The sensor is disk shaped and has a height which is a fraction of the fastener. Disk shaped measuring elements are welded under preload to a metal disk of the sensor and have a common planar surface.

Beam force measuring system for a cyclically operating machine having a plurality of beams secured to a force diverting part of the machine by a respective fastener and which is subject to cyclic forces comprising:
- a force sensor to be mounted to said beam between said force diverting part and a respective fastener;
- said force sensor including a metal disk having the dimensions of a normal washer, into which at least one disk-shaped measuring element is welded under mechanical preload.
A method of verifying the state of a cyclically operating machine having a plurality of beams secured to a force diverting part of the machine and which is subject to cyclic forces comprising:
- mounting a force sensor to each beam;
- positioning a calibration sensor at various positions in a plane transverse to said beams;
- monitoring signals from said force sensors and said calibration sensor;
- and
- determining the state of said machine from said monitored signals.
Beam force measuring system for a cyclically operating machine having a plurality of beams secured to a force diverting part of the machine by a respective fastener and which is subject to cyclic forces comprising:
- a force sensor to be mounted to said beam between said force diverting part and a respective fastener;
- said force sensor being a disk having a height which is a fraction of the height of said fastener and including a solid annulus and a top disk joined together tightly and having openings with measuring elements in the openings.
Beam force measuring system for a cyclically operating machine having a plurality of beams secured to a force diverting part of the machine by a respective fastener and which is subject to cyclic forces comprising:
- a force sensor to be mounted to said beam between said force diverting part and a respective fastener;
- and
- a mating member connecting said beam and said fastener for fixing the relative axial positions of said beam and said fastener.
