Displacement transducers

displacement transducer

The working principle of Meggitt’s displacement transducer is the measurement of the variable inductance of a linear coil. The temperature compensation is built into the sensor and achieved by measuring the resistance of the coil. The displacement measurement is made by measuring the reactance. The measurement system is lightweight and especially suitable for OEM avionics applications. This type of displacement transducer reduces the length of the space envelope by about 40% compared with LVDTs.

Typical applications are

  • Fuel regulation systems on jet engines
  • Variable pitch blade servo systems for turbo engines
  • Control of actuated surfaces on aircraft structures
