Geared RVDT

RVDTs with integral gear heads are available for applications with higher angular displacements or multiple revolutions.

In those cases where many input revolutions must be measured for position such as in trailing edge flap systems, Kavlico can provide a high precision gear head to extend the input range into the thousands of revolutions range.
