The R30A RVDT (Rotary Variable Differential Transformer) is
an angular position sensor that incorporates a proprietary non-
contact design which dramatically improves long term reliability
when compared to other traditional rotary devices such as
synchros, resolvers and potentiometers. This unique design
eliminates assemblies that degrade over time such as slip
rings, rotor windings, contact brushes and wipers, without
sacrificing accuracy.
High reliability and performance are achieved through the use
of a specially shaped rotor and wound coil that together
simulates the linear displacement of a Linear Variable
Differential Transformer (LVDT). Rotational movement of the
rotor shaft results in a linear change in the amplitude of the
output signal, directly proportional to the shaft angle change,
while the phase of this output signal indicates the direction of
displacement from the null point. Non-contact electromagnetic
coupling of the rotor provides infinite resolution thus enabling
absolute measurements to a fraction of a degree.
AC operation eliminates the need for integrated signal
conditioning components, thereby offering the user an
extremely wide operating temperature range of -55°C to
+150°C. Factory calibrated to operate over a ±30 degree
range, the R30A offers a non-linearity of less than ±0.25% of
full range. Extended range operation up to a maximum of ±60
degrees is possible with increased non-linearity. Packaged in
a small, size 11 servo mount, aluminum housing with flying
lead termination, the R30A is ideal for space restrictive
applications.
