Abstract

A cuff type clamping force sensor is mounted around a surface of a load-bearing round column of a forming machine, so as to measure any stretch, tension, and surface stress of the load-bearing round column. The clamping force sensor mainly includes a cuff-type locating seat, at least one cushion pad, and at least one strain meter. The strain meter includes a sensing element, two signal lines of which are vertically inserted through the cushion pad and the locating seat to connect with an amplifier base board fitted in the locating seat to form contacts. The internally provided amplifier base board allows reduction of the space for a working site, simplifies the procedures for setting the amplifier, gives the clamping force sensor an increased mobility, and enables amplifying and sending of a signal from the strain meter without distortion.
