ABSTRACT:
A tie rod load sensor for a die-casting or other machine includes an axially-extending bore formed in the tie rod to receive a strain gauged sensing member. One end of the sensing member is countersunk to receive a ball which concentrates the load when it is forced against the bottom of the bore by a bolt threaded into the opening of the bore. The sensing member includes a narrow central shaft portion upon which a plurality of strain gauges are mounted. The bolt is utilized to pre-load the sensing member such that the strain gauges mounted thereon will measure changes in the tension on the tie rod.
