ABSTRACT:
An indicator for sensing the degree of tension in a tensile member. An indicator element defined by a deformable elastomeric member is positioned within a translucent containment wall. Upon application of a tensile force to the tensile member the indicator element is caused to be compressed and expanded radially outwardly into contact with the containment wall. The degree of contact of the indicator element and the containment wall varies as a function of the amount of tension applied to the tensile member. As a consequence the appearance of the indicator element as viewed through the translucent containment wall will vary as a function of the tension applied to the tensile member.
The invention also has application in compression systems. One particular application disclosed is an indicator for sensing the appropriate degree of compression as applied to glass curtain walls used in dry pressure glazing systems.
