SUMMARY

This discussion centers on the search for wireless alternatives to LVDT (Linear Variable Differential Transformer) probes for measuring linear displacement. Users express frustration with the cumbersome wiring of traditional LVDT probes, which complicates machining processes. Recommendations include a Bluetooth Low Energy system from Motionics that is compatible with Mitutoyo linear gages, providing a high-resolution solution for detecting motion in the micrometer range.

PREREQUISITES
  • Understanding of LVDT technology and its applications in linear displacement measurement.
  • Familiarity with Bluetooth Low Energy (BLE) communication protocols.
  • Knowledge of high-resolution measurement techniques.
  • Basic machining principles related to sensor integration.
NEXT STEPS
  • Research the specifications and compatibility of Motionics' Bluetooth Low Energy system for LVDTs.
  • Explore alternative wireless sensor technologies for linear motion detection.
  • Investigate high-resolution measurement techniques for applications requiring micrometer precision.
  • Learn about the integration of wireless sensors into existing machining setups.
USEFUL FOR

Engineers, product designers, and technicians seeking efficient, wireless solutions for linear displacement measurement, particularly those currently using LVDT probes in their applications.

Hello there,

I am currently using LDVT probes to measure linear displacement (goes without saying, but I said it anyway). The problem with this is that the wire for the probe is very cumbersome and requires extra machining to external parts in order to accommodate the wire without disruption. Therein, some of the machining may be causing disruption itself!

I typically don't get into the details of the equipment used, though I think it's finally time to start looking at alternatives. Problem is, I don't really know where to begin.

Does anyone know of any wireless alternatives to LVDT probes? Essentially anything wireless that can detect linear motion; the smaller and less cumbersome the better, regardless of price. Preferably with high resolution (able to detect movement on the order of microns).

Thank you everyone.

How about this?
http://motionics.com/products.html?panel1=0&panel2=2
Its a wireless (bluetooth low energy) system for LVDTs. It is compatible with most of the LVDTs (linear gages) from Mitutoyo. Contact me if interested mosenn@gmail.com
