Output Signal
Celesco’s model RT8101 provides a voltage feedback signal for rotational position. The sensing element of this device is a precision plastic-hybrid
potentiometer
which provides superb linearity and resolution.
The RT8101 provides extended rotational position feedback from as little as 1/8 of a turn f.s. all the way up to 200 turns f.s. Because the
sensor is potentiometric,
the RT8101 is absolute and will maintain position
information even after a loss of power.
