ABSTRACT:
The present invention relates to a digital tram gauge assembly having an extendible elongate tram bar having a first height rod at a first end and a second height rod at a second end. A digital measuring device is positionable about the tram bar and is capable of digitally sensing, displaying and wirelessly transmitting measurement data from the digital tram gauge. The digital measuring device further includes a digital level sensor that functions as a digital level comparator to indicate whether the tram gauge assembly is oriented substantially parallel to a user-defined reference datum plane.
