Bestech Australia  offers U05 (65) series of miniature eddy current displacement sensors from Micro-Epsilon, Germany. The diameter at the sensor face is 2.3mm and the overall length measures 5mm.

The U05 (65) series of miniature eddy current displacement sensor is connected via an integral coaxial cable having a diameter of only 0.5 mm and a 3 m long extension lead to the electronics.

The U05 (65) series of miniature eddy current displacement sensors measure the distance to all types of metal surfaces without making contact. The metal may be non-magnetic or ferro-magnetic. The functioning principle is based on the extraction of energy from a high frequency oscillating circuit by the induction of eddy currents in the metallic target. The sensor housing is produced in ceramic and is, therefore, particularly resistant to harsh ambient conditions.

The U05 (65) series of miniature eddy current displacement sensor can work in temperatures of up to 150 °C and gaseous or liquid pressures of up to 1000 bar.

When used in conjunction with controllers in the multi/eddyNCDT Series, linearity deviations of only 1 µm is achieved in a measurement range of 0.5 mm. The resolution is specified as 50 nm. Frequency response of up to 100 kHz is possible with the U05 (65) series of miniature eddy current displacement sensor.

The U05 (65) series of miniature eddy current displacement sensor sensors find application in the following:

  • Internal combustion engines for the measurement of piston or piston-ring movement
  • Oil gap in the big-end bearing
  • Pin movement in the crankshaft bearing
  • Valve positions
  • Jet-needle stroke

The U05 (65) series of miniature eddy current displacement sensors are available in Australia and New Zealand from Bestech Australia.
