R30D DC Operated, Light Weight RVDT SPECIFICATIONS Bipolar DC operation 60 degree sensing range Light-weight Non-contact electrical design Wide operating temperature range Size 11 servo mount Anodized aluminum housing The R30D RVDT (Rotary Variable Differential Transformer) is a DC operated non-contacting rotary position transducer. Integrated signal conditioning enables the R30D to operate from a bipolar 15 VDC supply, and provide a high level DC output that is proportional to the full angular sensing range of the device. Calibrated for operation over 30 degrees, the R30D provides a +/-3.75VDC output, with a non-linearity of less than 0.25% of full range. Extended range operation up to a FEATURES maximum of 60 degrees is possible with increased non- o Extended operation up to 60 linearity. High level, low noise DC output Internally, the DC supply voltage is converted into an AC carrier Long term reliability signal which excites the primary coil of the sensor. An integrated Excellent temperature performance demodulator amplifier with low-pass filter converts the Rugged anodized aluminum differential secondary output into a smooth, high level, linear DC housing output signal relative to the angular position of the shaft. Shielded ABEC 3 precision bearings High reliability and performance are achieved through the use of a specially shaped rotor and wound coil that together simulates APPLICATIONS the linear displacement of a Linear Variable Differential Hydraulic pump control Transformer (LVDT). Non-contact electromagnetic coupling of the rotor provides infinite resolution thus enabling absolute Throttle lever position feedback measurements to a fraction of a degree. Rotary actuator feedback Dancer arm position The R30D features a rugged aluminum size 11 housing making Reeler/Dereeler this rotary position sensor ideal for applications where integrated Valve position signal conditioning and small size are required.
