Kaman Precision Products' DigiVit Eddy-Current Sensor
DigiVit eddy-current sensor for position/displacement/proximity sensing has a self-tuning bridge — no need to connect to a PC to download a configuration file when changing sensors or doing high-level calibrations. The device detects the sensor coil parameters with the target being used. The bridge that balances the circuit is automatically tuned for optimum performance for that calibration range and target material. It will work with virtually any manufacturer’s inductive sensor.
