Introduction
ProScale™ digital measuring systems are affordable precision electronic devices for
making linear measurements with speed and accuracy. ProScale consists of a scale, a
readhead (or encoder) and a digital display. It uses capacitive encoder technology, the
same technology used in digital calipers.
Because ProScale is a solid-state electronic device there's very little to wear out. The
readhead and scale are designed to withstand shop dirt, dust, and other airborne
contaminants, and the controls are sealed with a protective cover. With normal care,
ProScale will last for years.
ProScale is ideal for most measuring requirements up to 6m (20ft.) where high accuracy,
10 m, (approximately .0005”) is not needed, but affordable repeatability, (better than a
tape measure), or accuracy to 50 m (.002”) is desired. Because ProScale shows the
exact measurement on its display, it eliminates the guesswork involved in reading and
interpreting tape measures, scales & pointer, or shaft encoders. It is compatible for
retrofitting, or as original equipment, on most machinery or for any general purpose
measurement application where data is collected (SPC, RS232, RS485) and/or digital
accuracy and repeatability is desired.
