Abstract
A load sensing probe for monitoring working forces in compressive elements such as found in presses and other machine tools is disclosed. The probe has an elongate configuration which allows it to be mounted at a point remote from its load sensing end and enables it to be conveniently used with a plurality of similar probes in relatively confined spaces. A split plug includes a slot defining two sensing arms, which arms are pushed outwardly into engagement with an accommodating cavity formed in a back-up member of the machine tool. The probe is sensitive to relative closing movement of the cavity caused by compressive strain in the back-up member.
