Eddy current sensor T14/T20/T40

High-quality eddy current probes: Beside robustness, high dynamics and high resolution the TX-Series also stands out with a wide temperature range from -60 °C up to 180 °C. ■ High precision measurement ■ High resolution (submicrometer) ■ High dynamics (124 kSa/s) ■ Minimal temperature coefficient ■ High noise immunity ■ Custom-made probes

eddyMOTION is a Windows-based analysis and configuration tool for eddy current probes. In combination with the TX electronics from eddylab GmbH, the software tool combines several performance features: The functional areas oscilloscope, FFT analysis, data logger and waterfall diagram, enables the visualization and documentation of mechanical movements. eddyMOTION also suites the on-site linearization of eddy current sensors in a traceable manner, without external assistance. In addition to the TX electronics and an eddylab eddy current sensor, a reference probe is required for this purpose: Together with the eddy current sensor, this probe measures the distance to the same material, with the reference probe serving to check the sensor.

■ Measuring on turbo vanes and shafts ■ TTL output for speed measurement ■ Analogue monitor output for gap control ■ High resolution ■ High dynamics ■ Low current consumption ■ High noise immunity

The CM-Sensors are specially designed for demanding applications: They withstand high pressures up to 100 bars (and more) at temperatures up to 190 °C. At conventional sensors with a similar size the probe head must be kept free from surrounding conductive objects, in order to avoid pre-attenuation of the measuring system. In contrast, the socket for the CM-sensor does not require additional notches or holes.This feature arises from the utilization of zirconium oxide as housing material and ferritic components with a focusing effect. The CM-sensor is typically applied to monitor the orbit of a turbocharger’s shaft.Its ball bearings have a squeeze film damper to reduce the rotor vibration. In order to optimize the entire system the CM-sensors detect the exact position of the turbine- and compressor wheel under real operating conditions.
