    Product Description

    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 -55oC to +150oC. 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.

    Also see our other angular position sensor models, R36AS (stainless steel housing, MS style connector), RSYN (high output, shock and vibration tolerant), R30D and R60D (bipolar DC operation), and the RVIT-15 Series (single ended DC operation, voltage or current output).
