Kavlico Multi Channel RVDT

Kavlico RVDTs are the industry standard for angular and rotary measurements in aviation applications. The lightweight, robust sensors are capable of ±80° angular range in single and multiple channel designs. RVDTs with integral gear heads are available for applications with higher angular displacements or multiple revolutions. Typical RVDT applications include: Stand-alone airframe and cockpit applications Used for integral parts of flight control actuator or servo valve systems Multi-Channel RVDTs When the design of a system requires more electrical redundancy to achieve the necessary system reliability, multi-channel RVDTs are the sensor of choice. This is often the case for military fly-by-wire aircraft. Up to three separate channels can be placed in tandem inside a common housing. A common shaft will mount three separate rotor stacks each directing flux in different stators mounted in line. Another multi-channel option is to mount the channels in parallel. This allows a greater number of independent channels in a shorter housing, although the diameter of the total package size must increase. This approach allows for easy replacement of each channel as discrete single channel RVDTs are used to build the multi-channel unit. Each channel is connected to the input shaft via a single anti-backlash gear.
