Modular non-contact displacement measuring system KD8206

Principle of operation

The KD-8206 eddy current sensor measures displacements, positions or distances, without contact, between the sensor head and a magnetic or non-magnetic metal part, over measurement ranges from 0.5 to 60 mm. With the same technical specifications as the KD2306 (resolution down to 0.1µm), frequency response of 50 kHz, use in wet, electro-magnetic, cryogenic and cutting oil environments, the KD8206 is recommended for instruments using 4 or more sensors simultaneously. The acquisition cards are installed in a specific rack or cabinet and the different measurement points are synchronised. The analogue output signal (DC voltage or 4-20mA) is compatible with any analogue input from a PC, PLC or data acquisition system.

Calibration / adjustment

The calibration of the KD-8206 is performed at the factory, with the probe and the metal target of the application, under the measurement conditions (temperature, supply voltage, etc.). As an option, calibration points can be specified to optimise accuracy. When installing the system or using a new metal target, the gain and offset of the amplifier can be adjusted by screw potentiometers to optimise the linearity of the response. Shims and micrometers for this purpose are optional.

Configuration

The KD-8206 system consists of a probe with integrated cable (29 models available) and conditioning electronics that can be installed in a rack or table top case.
