Hall Effect Technology
Temposonics' linear position sensors utilizing Hall Effect technology are able to determine position with a high level of repeatability and robustness. The sensor consists of sensing elements and supporting electronics in a robust sensor rod. The non-contacting position magnet is attached to the object in motion for the given application. The magnetic field, of the position magnet, perpendicular to the sensing elements creates a measurable (Hall) voltage which is proportional to the strength of the magnetic field. The Hall voltage is then converted into a linear position measurement. Since the output of the sensor corresponds to an absolute position, rather than a relative value, recalibration is not required.
