R60D DC Operated Rotary Variable Inductance Transducer SPECIFICATIONS Lower cost than RVDTs Bipolar DC operation 60 degree sensing range High level VDC output Light-weight Non-contact electrical design Size 11 servo mount Anodized aluminum housing The R60D RVIT (Rotary Variable Inductance Transducer) is a DC operated non-contact angular position sensor. Operating on a 15VDC supply, the R60D provides a smooth 7.5VDC output proportional to angular position over a 60 degree sensing range. FEATURES Wide temperature range The RVIT proprietary design utilizes a set of four printed circuit coils and a light-weight conductive spoiler to achieve superior 7.5VDC output performance with a low moment of inertia. During operation, the Internal voltage regulation light weight spoiler rotates with the transducer shaft, Low moment of inertia differentially altering the inductance of the printed circuit planar Shielded ABEC 3 precision bearings coils. The resulting unbalance is precisely measured using a Rugged aluminum housing patented autoplex circuit. This signal is then converted to a linear DC output voltage, proportional to the angle of the rotor shaft. The digital circuit is extremely resistant to environmental APPLICATIONS disturbances such as EMI and RFI, and is compatible for use with most analog position feedback systems. Ball valve position Throttle level position feedback Calibrated for use over the full 60 degree sensing range, the Rotary actuator feedback R60D offers exceptional performance at a cost effective price. Dancer arm position It also features a wide operating temperature range, infinite Reeler / Dereeler resolution, and an extremely long rotational cycle life.
