Schaevitz® RVDT Transducers- R30D Series
The R30D RVDT is a DC operated non contacting 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.
