ProScale Terminology
All ProScale systems consist of a SCALE, a READHEAD, and a DIGITAL DISPLAY.
The SCALE consists of a series of conductive patterns bonded to an aluminum extrusion.
The READHEAD, or encoder, contains a computer chip which transmits and receives
signals to and from the scale using capacitive coupling. The received signal is used by
the readhead to calculate its position to within 10 microns (10µm / .0004in). This position
data is then sent to the digital DISPLAY, where it can be displayed in millimeters,
centimeters, inches, or fractions and sent to an external data acquisition device.
Each SCALE and READHEAD uses either Incremental or Absolute encoder technology.
Absolute, (often referred to as ABS) systems use a more robust and sophisticated
method to measure position, resulting in a high immunity to electrical interference and
one that does not forget its position when power is removed. The type of system you
have (absolute or incremental) may be determined by the pictures and descriptions on
the following pages of this manual, by reviewing our web site, by the label on the
packaging, or by contacting your supplier.
