ProScale 150B Absolute Linear Encoder


Model 150B is a linear encoder with a fixed gap on the encoder. Measuring ranges up to 24 inches (600mm). High slew rate, ultra-low power consumption, and very high EMI immunity make this absolute encoder an excellent fit for most machinery and gaging applications. (Battery power only.) Four stock digital readout options are available.

ProScale Model 150B uses Capactive Absolute measuring technology.
These encoder systems are ideal for machinery applications or any measuring environment where the need to always remember its position is important.
This system may be used in a 'Scale Stationary, Encoder Moving' or a 'Scale Moving, Encoder Stationary' configuration.
For applications that do not require absolute technology, consider Model 190.

Select the Model 150 for Battery operation and applications employing a WIRELESS data transmitter.

Do not use the ProScale 150B system in externally powered applications or where WIRED/CABLED data acquisition is required.


  • No Gap to Set: All Encoders are "captive" on the Scale so you never need to set the Encoder gap.
  • Battery Operation: Readouts are available that operate on battery.  For externally powered applications, use the 150G linear encoder systems.
  • Accuracy: +/- .002 inches when installed correctly.
  • Repeatablitly: +/- .001 inches when installed correctly.
  • Resolution: All readouts support inches to 4 decimal places, millimeters to 2 decimal places.  Most readouts can display fractions to 1/64th divisions.
  • Set and Forget: ProScale 150B with Absolute Technology will remember its place even when power is lost.
  • High Noise Immunity: Electrical noise, magnetic fields, or power transients affecting the measurement accuracy or signal integrity is rare.
  • Scalability: The ProScale 150B 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 12 inches per second.
  • RoHS compliant Lead Free Product
  • MADE IN USA: 3 year warranty
