The new compact, high performance eddy current sensor from Micro-Epsilon boasts features that surpass those of its competitors. Designed for fast, high precision displacement, distance and position measurements, the eddyNCDT 3005 system comes with active temperature compensation, is pressure-resistant up to 10 bar and can withstand operating temperatures of up to 180°C due to the compact electronic housing being integrated into the cable one metre from the sensor head. The system is factory-calibrated, making it ideal for machine integration, as well as for single or volume OEM requirements.
Chris Jones, Managing Director at Micro-Epsilon UK comments: “The eddyNCDT 3005 sets new standards in terms of eddy current displacement measurement. The complete conditioning electronics has been miniaturised and mounted into a compact cylindrical housing, integrated into the sensor cable, one metre from the sensor head. Having the electronics remote from the sensor enables more compact sensor dimensions and higher operating temperatures, compared to sensors with integrated electronics.”
“With a very competitive pricing structure, the system can be supplied from stock in lower quantities. Equally, for higher volume applications, the system can be modified to suit individual OEM requirements. We expect to see interest from a wide range of companies that need to measure vibration, shaft runout, concentricity, gap, tip timing, eccentricity, oil film thickness and position, to micrometre level accuracies,” adds Jones.
Pressure, dirt, oil and high temperatures have almost no influence on measurement precision. The eddyNCDT 3005 has temperature-compensated electronics, which provides high measurement stability (0.05% FSO) even in high or fluctuating ambient temperatures. The sensors are designed for ambient temperatures up to a maximum of 125°C but the series also includes an optional, high temperature version for up to 180°C. The eddyNCDT 3005 controller, cable and sensor are pressure-resistant up to 10 bar.
该eddyNCDT 3005是工厂校准为铁和非铁磁性的材料，从而消除了任何现场校准的需要。 鲁棒IP67传感器设计，与真正的涡流测量原理相结合，使在恶劣的工业环境（油，压力，污垢，灰尘），以及对于某些近海和海洋应用（盐水抗性）测量由于其不锈钢施工。
A range of sensors are available with measuring ranges from 1mm up to 6mm for use on steel or aluminium measuring objects. Frequency response is 5kHz (-3dB) and temperature compensation range is from 10°C to +125°C.
Micro-Epsilon’s range of eddy current sensors also includes the eddyNCDT 3001 series, eddyNCDT 3100 series, the eddyNCDT 3300 series, turbocharger speed sensors (turboSPEED DZ140) and the Spindle Growth System (eddyNCDT SGS4701).
eddyNCDT 3300系列广泛用于需要最高测量性能的场合。 例如，在汽车研发中，它们用于测量阀门行程，注射针运动，气缸盖呼吸，润滑间隙，油膜厚度，曲轴同心度和曲轴的轴向运动。 此外，eddyNCDT 3300还有许多其他潜在用途，例如电机，泵，轴承和旋转机械中的振动监控，或用于测量金属生产中带材厚度或带材位置控制的用途。
In addition, the eddyNCDT 3100 series represents a world first in eddy current displacement measurement. With its Smart Sensor Auto Calibration system, the sensor can be connected easily and quickly to the 3100 controller. All calibration data is then automatically uploaded from the sensor to the controller, with no need for any lengthy calibration. All calibration data required for both ferrous (St37) and non-ferrous (aluminium) target materials is stored in the sensor before it is shipped. User-specific target materials can also be measured accurately using Micro-Epsilon’s push-button, 3-point linearisation.
The eddyNCDT 3100 controller is equipped with many new features, including Ethernet connection for output signal and configuration. The configuration of the controller can be performed from the user’s web browser by simply typing in the controller IP address – no additional software needs to be downloaded. All controllers are supplied with a default IP address that the user can amend later to a specific IP address.
