ProScale Model 190 Measuring System


ProScale Model 190 shown with Encoder & Connector Link                            End View of Scale profile

ProScale Model 190 uses SERIES II Incremental Inductive measurement technology.
This system is an affordable choice for most common measuring applications up to 18 inches (450mm).
This system may be used in a 'Scale Stationary, Encoder Moving' or a 'Scale Moving, Encoder Stationary' configuration. The maximum encoder speed is 120 inches per second.


  • No Gap to Set: All Encoders are "captive" on the Scale so you never need to set the Encoder gap.

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

  • High Noise Immunity: Inductive technology reduces the likelihood of motor electrical noise, magnetic fields, power transients and ESD from affecting the measurement.

  • Scalability: The M190 supports multiple Encoders and Readouts operating simultaneously on the same Scale.

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

  • Encoder Speed: up to 120 inches per second.

  • RoHS compliant Lead Free Product

  • LIFETIME limited warranty.
