NewTek Expands LVDT Displacement Line with High-Performance, Non-Contacting Analog Rotary Position Sensors

NewTek Sensor Solutions introduces the RV series of RVDT Rotary Position Positions 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°.

RV Series Valves Background

RVDTs (Rotary Variable Differential Transformers) are known for reliability and ruggedness in extreme environments, with a non-contacting design 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 over a temperature range of -65°F to 220°F and exhibit a linearity error of less than 0.5% of full range.

NewTek offers the RV series in both a size 8 (0.75”) and size 11 (1.06”) diameter with standard servo mounts for immediate shipment. Operating from 7.5 V rms (nominal), the AC-operated RVDTs provide an analog signal output that can be used with NewTek’s NTC-6000 Signal Conditioner for a complete measurement solution.  The RV sensor can operate in the harsh conditions while the signal conditioner is stationed in a nonvolatile area for greater system longevity and reliability.

The RVDT joins NewTek extended line of Linear Position Sensors and signal conditioners, enabling the company to address a greater range of angular and displacement measurement applications.     For more information about NewTek RV Series of Rotary Position Sensors, refer to the website at http://www.newteksensors.com/products/rv-series-rvdt/ or contact Mike Marciante at 856-406-6877 to discuss your application requirements.
