Compact eddy current sensor with integrated electronics

Although the sensor is similar in size to a typical proximity or inductive sensor, its measuring performance is much greater, making it ideal for OEM applications.

All conditioning electronics on the eddyNCDT 3001 are completely integrated into the sensor housing. However, the compact M12 dimensions do not mean lower performance; the sensor’s temperature-compensated electronics provides high measurement stability (0.03% FSO) even in fluctuating ambient temperatures.

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.

Micro-Epsilon has also added a range of high performance acceleration, inclination (tilt angle), shock/vibration sensors and other industry-specific MEMS-based sensors to its portfolio.

Standard industrial analogue sensors include the AccSENS 5, an industrial sensor that measures acceleration, as well as inclination and vibration. A micro-mechanical spring-mass system continuously measures acceleration (including gravitational acceleration), which also enables inclination to be determined.

For higher acceleration measurements, the AccSENS 10 sensor has very low thermal drift. This range also includes the AccIS 10 (illustrated), a high resolution inclination sensor with linear analogue output, which measures acceleration but offers smaller measuring ranges.

The digital sensor range includes the AccIS 100 inclination sensor and the AccSENS 100 acceleration sensor. Compact and robust, these sensors continuously measure gravity/acceleration and provide long term stability for high precision measurement tasks. An integrated miniature controller calculates the calibrated inclination values.
