    Product Description

    The RVIT 15-60 and RVIT 15-120i are DC operated, non-contact, angular position sensors featuring MEAS proprietary RVIT (Rotary Variable Inductance Transducer) technology. Operating from a single rail DC voltage supply, they provide either a +3VDC (RVIT 15-60) or 4-20mA (RVIT 15-120i) output, over a 120 degree angular sensing range.

    The RVIT design utilizes a set of four printed circuit coils and a light-weight conductive spoiler to achieve superior performance with a low moment of inertia. During operation, the light weight spoiler rotates with the transducer shaft, differentially altering the inductance of the printed circuit planar coils. The resulting unbalance is precisely measured using a 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 disturbances such as EMI and RFI, and is compatible for use with most analog position feedback systems.

    The RVIT 15-60 and RVIT 15-120i offer exceptional performance at a competitive price along with the interfacing flexibility of the +3 VDC and 4-20 mA outputs. The RVIT 15-60 emulates a potentiometer in that the output voltage is ratiometric to the supply voltage, within the limits of the specification. Other standard features include a wide operating temperature range, infinite resolution, and an extremely long rotational life. For higher volume applications, specialized options include special angular sensing ranges, and custom unipolar or bipolar output voltage scaling.
