Position Sensor Technology Overview

Zettlex position sensor technology uses a unique inductive technique. The basic position sensing principles are similar to traditional inductive proximity switches or measuring transformers but rather than wire windings or spools, Zettlex position sensors use printed circuit boards (PCBs). Advantages of Zettlex inductive position sensing technology include:-

  • High accuracy
  • Stability irrespective of environmental conditions
  • Measurement performance largely independent of installation tolerances
  • Insensitivity to foreign matter
  • Compact size
  • Lightweight
  • Ability to sense over a wide range of geometries
  • No need for bearings, bushes or seals
  • Can also be used to measure weight, vibration, strain, shock, tilt, pressure and even temperature (by expansion).

The use of PCBs means that a bespoke shape or size of sensor is readily engineered to suit a specific application – especially for OEMs.

Zettlex sensors are most frequently used as part of a control system to measure absolute linear position or angle (single turn or multi-turn).

Measurement ranges vary greatly – from 0,1mm to 10m and topologies include rotary, linear, 2D, 3D etc.
