New wireless versions of eddy-current displacement sensors
Lion Precision is introducing wireless eddy-current displacement sensors, which are adapted from the company's existing high-precision eddy-current sensors. Machine designers and production engineers will benefit from remote measurement of production variables and machine performance. The wireless system is particularly useful when sensors must be installed in difficult-to-access areas or on moving elements of machinery. When using Wi-Fi technology, the sensors are capable of very high data streaming speeds for real-time monitoring of position and displacement in high-speed operations. Other wireless interfaces are also possible such as Bluetooth and Zigbee, but with lower data transfer rates.
Lion Precision eddy-current sensors measure positional changes of conductive metal targets over ranges from 0.25mm to 15mm with measurement resolutions as low as 10nm. These levels of precision are required in many manufacturing environments including semiconductor processing, motion control, aerospace, precision metal manufacturing and computer disk drive production. Traditional wired systems require that data acquisition be performed near the sensor system via connecting cables. Increasing the length of the connecting cables can degrade the high-precision performance of the system, making implementation difficult in some applications.
The wireless system is a printed circuit board intended for OEM use by machine manufacturers. The system can use the standard Lion Precision eddy-current probes with similar performance to the ECL202, the company's highest-performance eddy-current displacement sensor.
