TX SERIES | EDDY CURRENT PROBES 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-

For more than twenty years we have been occupied with the development and production of high-quality eddy current probes for industry and research. With the new TX Series, eddylab is introducing a fully digital device – incorporating USB, CAN and a high-speed analogue interface. Eddy current probes are particularly suitable devices for non-contact measurements on metallic targets. Typical applications are measurements on rotating shafts for the detection of imbalance, vibration, out-of-roundness, air gap, radial/axial run-out, and much more besides. The extremely high resolution up to a...

TX SERIES | BASIC MODULE TX EDDY CURRENT BASIC MODULE TX The processor based design admits linearities less than 0.1 % – which is an exceptional feature for this sensor technology. Remarkable performance allows highly dynamic measurements with 124 kSa/s. The TX-Driver is available as single- or dual-channel device. As standard, the device provides a USB and a CAN-bus Interface. The power supply is a galvanically isolated wide input from 10.5..36 (27) VDC. All available sensor heads can be connected with the basic module TX (page 5-6). ■ Probe and analogue output: Wide-Input-supply 10,5...36...

12 SOFTWARE EDDYMOTION | TX SERIES A well known issue when it comes to eddy current measurements is the strong sensitivity to varying target material and pre-attenuation. The maximum scaling error under varying material can be 20 % or more. The linearity error can be 7 % or more. Another severe error source affecting the accuracy is pre-attenuation. This effect has to be taken in account when the sensor is mounted in narrow gaps and holes. The error due to pre-attenuation is hard to predict - but in most cases higher than expected. The TX-Driver in conjunction with eddyMOTION resolves the...
