ABSTRACT:
A coupler interconnects an expanding plug gage head with an electronic amplifying and displaying device. The gage head includes a tapered plunger which is pressed into an internal socket to expand the plug gage. The coupler includes a transducer which electrically relays the position of the tapered plunger to an electronic amplifying/indicating device. The coupler is interconnected with the plunger and includes a spring for imparting to the plunger a plug gage expanding force. The coupler also includes a slotted lever to which the plunger is connected and which is manually actuated to retract the plunger for contracting the plug gage preparatory to its insertion into a bore to be measured in a workpiece.
