coreFIELD is a compact 2-channel strain gauge measuring amplifier with contactless energy transmission via induction. The sensor values are transmitted via radio at up to 1,000 Hz and output at the evaluation unit via digital and analog outputs. A total of 8 configurable analog outputs are available. The measuring electronics have an additional battery and can thus bridge short as well as longer interruptions.

Sensor
In combination with coreIN, the rotor-side measuring amplifier is installed directly inside the component. The coil is wound around the component on two half-shells in a speed-resistant manner. Alternative coil geometries (e.g. face-side coils) are also possible.
coreGATE
The evaluation unit included in the coreFIELD package (identical in construction to coreGATE) has 8 analog voltage outputs, as well as digital IO interfaces.
Pickup
The pickup consists of a stator coil and the antenna for receiving the data. The pickup is placed at a distance of approx. 1-10 mm. Optionally, an external speed sensor can be installed in the pickup.
