Abstract
A caliper tool for measuring internal dimensions of an enclosure with the tool including a housing of a size to fit within the disclosure and several feeler arms attached in a rotatable fashion to the tool housing with each feeler arm extending outwardly from the tool housing to engage the interior surface of the enclosure. A control apparatus is provided and attached to the tool housing for controlling the location of the tool housing within the enclosure. A mechanical apparatus contained within the tool housing is attached to the feeler arms and provides a translation of the rotational positions of the feeler arms into linearly displaced positions. Magnetostrictive linear displacement transducers are connected to the mechanical means to convert the linear displacement positions into electrical signals representing these positions. Interface circuitry located external to the enclosure is connected to the control apparatus and the transducer for providing input signals to and for receiving output signals from the transducer and further to display the output signals as a visible display of the internal dimensions of the enclosure.
