ProScale Model 590 Measuring System

ProScale Model 590 shown with Sliding Carriage and Encoder                        End View of Scale profile

The ProScale Model 590 uses SERIES II Incremental inductive measurement technology.
It is a general purpose measuring device with an integrated iGlide
friction bearing system. The Model 590 uses a custom extrusion design incorporating a dual rail for the bearings. A sliding carriage assembly captures the Encoder and moves along the scale minimizing pitch & yaw of the encoder for the utmost in accuracy and repeatability.
The Model 590 was designed as a stand alone measuring system or to be the foundation of systems designed by end users for their particular dimensional measurement applications.

NOTE: Beginning in December 2016, all scales will be CLEAR Anodized instead of Black.


  • Battery or 12-24 VDC Operation: Readouts are available that operate on battery or 12-24 VDC.

  • High Speed Encoder: The carriage/encoder can be moved up to 80 inches per second.

  • Versatility: The carriage plate has several holes predrilled for mounting a Readout, a wireless data transmitter, a handle or other features as required for a custom application.

  • Wireless Data: Systems are available with 2 way ProRF-SPC or Encoder wireless data transmitters.

  • Enhanced Accuracy: Systems ordered with a General Purpose E Readout incorporating non-linear scaling and temperature compensation may be calibrated in-place to enhance overall system accuracy.

  • High Noise Immunity: Inductive technology reduces interference from magnetic fields and ESD.

  • Scalability: The 590 supports multiple Encoders and Readouts operating simultaneously on the same Scale.

  • LIFETIME limited warranty.
