Product Description

The unique design of the RVIT-Z incorporates our proprietary RVIT (Rotary Variable Inductive Transducer) technology and the signal conditioning circuitry on a single printed circuit board. The RVIT-Z provides an ultra low profile, high accuracy, and infinite resolution solution for rotary and angular measurements in OEM applications. The absence of wipers, brushes, slip rings or magnetic materials eliminates wear, static friction, hysteresis and electrical noise while providing a very low rotor moment of inertia. Capable of absolute rotary measurement over ±60 degrees and extended operation up to ±75 degrees (with increased non-linearity), the RVIT-Z provides unsurpassed performance over an extended operating temperature range. Factory calibration and automated testing assures a non-linearity of less than ±0.5% of full range (±60 degrees). The RVIT-Z provides a high degree of design flexibility for optimum integration into customer applications. Where remote sensing is required, the RVIT-Z can be tailored allowing the rotary sensing element to remain separated from the electronic circuitry by as much as 12 inches.
