RVDT Rotary Variable Differential Transformer
A range of Size 11 Brushless Rotary Variable Differential Transformer with analogue angular outputs has been developed for measurement, motion and control applications.
They have a single phase excitation generating an output sensibly linear wrt rotor angle.
Excitation Frequencies from 400Hz up to 2.5KHz at 2 to 10V give typical angular sensitivity of 133mV/degree with linearity accuracy of ±0.6% over ±20 degrees.
Our applications engineers can assist you in selecting the most appropriate version to suit your needs.
The basic types are:
TDPV115 Unsealed. Form, fit and functional equivalent to CTD 11PP141.
TDPV119 Sealed to IP65.
All of the above are suitable for use with Interface cards and Displays. See our accessories section for more information on what we can offer.
