Schaevitz® RVDT Transducers - RVIT-Z Series
The RVIT-Z series is the first in the series developed from Schaevitz® of flat non-contact rotary displacement sensors. The unique design of the RVIT-Z incorporates the proprietary RVIT (Rotary Variable Inductive Transformer) technology and signal conditioning circuitry on a single PCB. |

The RVIT-Z provides an ultra low profile, high accuracy solution for rotary and angular measurements in OEM applications.
The lack of wipers, brushes, slip rings or magnetic materials eliminates wear, static friction, hysteresis and electrical noise. Measuring a fraction the size of other rotary positioning sensors, the RVIT-Z is ideal for space critical rotary sensing applications; it is smaller, flatter and lighter than conventional rotary sensors.
Capable of absolute rotary measurement over ±60°, and extended operation up to ±75° (with compromised linearity), the RVIT-Z provides unsurpassed performance over an extended operating temperature range of -40°C to 125°C. Factory calibration and automated testing assures a nonlinearity error of less than ±0.5% of full scale. The RVIT-Z provides a high degree of design flexibility for custom designs.
For 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 -up to 12 inches.
