LVDT sensors have long been a go to solution for absolute linear position measurement in challenging, high vibration environments. However they are not well suited to more cost sensitive or compact designs. CambridgeIC's solution provides the robustness and precision of the LVDT approach in a deeply integrated package that lets product designers better control the cost and footprint of their sensing solution.

LVDT alternatives: robust and precise position sensing

Based on innovative resonant inductive position sensing technology, CambridgeIC’s position sensors use designs integrated into conventional PCBs to measure linear position. This gives an accurate sensor which has low integration costs, is stable over time and extremely robust. Designers can provide absolute linear, rotary and arc position measurement with high reliability in the most challenging applications, including linear actuators and float level sensors.

Where other sensors can't go

How challenging? This solution is very tolerant of dirt, dust, moisture, vibration and shock, misalignments and wide measuring gaps. It is particularly cost effective where there is limited room or the system needs to sense position on many axes.

This makes CambridgeIC position sensors suitable for many applications, including surveillance camera control, satellite steering, intelligent valves and automotive suspension systems. 

Not just linear measurement 

Designs are available for a huge range of geometries - arc position measurement, rotary position measurement and linear position sensing and support is available to design custom sensors.

Working with CambridgeIC position sensors is straightforward - sensor blueprints are available in Gerber format to integrate with customers PCB. These designs work with CambridgeIC’s central tracking unit chips (CTUs) to provide continuous calculation of target position. For evaluation or low volume production assembled sensor units are also available.
