The R30D RVDT is a DC operated noncontacting
rotary transducer. Integrated signal conditioning
enables the R30D to operate from a bipolar ±15 VDC
source with a high level DC output that is
proportional to the full range of the device.
Calibrated for operation to ±30 degrees, the R30D
provides a constant scale factor of 125 mVDC/degree.
Nonlinearity error of less than ±0.25% FS is achieved
while maintaining superior thermal performance
over -18°C to 75°C.
The DC excitation is internally converted to an AC
carrier signal which excites the transducer’s primary
coil. An integrated demodulator amplifier and filter
convert the differential secondary output into a
smooth, high level, DC output signal that is linear
with the shaft angle position. Resolution is infinite
enabling measurements to a fraction of a degree.
The R30D features a rugged aluminum size 11
housing making this rotary transducer ideal for
applications where integrated signal conditioning
and small size are required. Typical applications
include hydraulic pump control, rotary actuator
feedback, and throttle lever position feedback.
