NewTek Sensor Solutions has introduced the RV series of RVDT rotary position sensors that offer highly accurate angular displacement measurement of rotating elements such as quarter-turn ball and butterfly valves, actuators, throttles and dancer arm tensioners used in industrial machine-to-machine applications. With a shaft that rotates a full 360° with no stops and virtually no friction, these AC-operated rotary position sensors measure shaft angle position over a nominal range of ±30°.
RVDTs (Rotary Variable Differential Transformers) are known for reliability and ruggedness in extreme environments, with a non-contacting design that gives NewTek RV sensor extremely long operational life by eliminating components that wear or degrade over time. In addition to offering good noise performance, these AC-operated analog RVDTs are shock and vibration tolerant to provide excellent feedback even when operating in hostile conditions often found in challenging packaging and automation applications. Units operate within a temperature range of -65°F to 220°F and exhibit a linearity error of less than 0.5% of full range.
NewTek’s RV sensors can operate in the harsh conditions while the signal conditioner is stationed in a nonvolatile area for greater system longevity and reliability.
