Abstract
A strain measurement device to determine the amount of clamping force or pressure developed in a machine from the small amount of linear movement which results from strain on a predetermined part of the machine, such as a tie bar. The strain measurement device features an elongated arm which will pivot in response to such strain movement and amplify or magnify the amount of this strain movement. The strain measurement device also includes a sensing unit which will measure the amplified strain movement, and a circuit for converting this measurement into a signal indicative of force.
