Unmatched precision

Eddy current sensors are designed to provide maximum precision in harsh conditions. The sensors are resistant to dirt, pressure and extreme temperatures, it's these features that make eddy current senors one of the best performing sensors in extreme environments. With a maximum frequency response of 100kHz (-3dB) the sensors can operate at high speed in oscillation and vibration applications.

Inductive displacement sensors based on eddy currents
Inductive displacement sensors based on eddy currents are used for precise displacement measurements.

Robust sensor designs

Eddy current sensors measure electrically conductive targets, both ferrous and non-ferrous. Dust, dirt and oil and liquids do not affect the sensor measurement. This fact, combined with the sensor’s robust, temperature-compensated mechanical design, enable measurements in harsh, industrial environments.

  • Robust and reliable sensors IP67
  • Pressure-resistant models up to 2,500 bar
  • Resistant to oil, dust & dirt
eddyNCDT displacement sensors provide accurate measurement values even with fluctuating temperatures.

Active temperature compensation

Fluctuating temperatures can impact measurement results and cause measurement errors. This is why every eddy current measurement system from Micro-Epsilon features active temperature compensation that reconciles any thermal influences.

  • Active temperature compensation of sensor, cable and controller
  • Temperature range -40°C to +200°C and higher

Custom sensors for automation and OEMs

Requirements can occur where the standard versions of the sensors and the controller are performing at their limits or cannot be packaged into the application. In these instances, the eddy current systems can quite often be adapted according to customer specific requirements. Typical change requests include, modified sensor geometry or mounting methods, special target calibration (shape or material), modified cable lengths, specific measurement ranges, or sensors with integrated electronics.

For high volume applications, Micro-Epsilon is able to offer a bespoke design service to offer the required performance specification at the desired target price levels. Get in touch today to discuss how we can modified or design a sensor to your specific requirements.
