Reliable RVDT Technology for Rotary Position Measurement

The NewTek RV series is a family of RVDT rotary position sensors for industrial applications. RVDT technology is known for reliability and ruggedness in harsh environments. The non-contact design allows for extremely long operational life and reliability and eliminates internal components that might wear or degrade over time. With a non-contact measurement, RVDTs offer good noise performance with excellent repeatability.  The NewTek RV series is available in two sizes – The RV 8-30 is a size 8 (0.75 inch diameter) and the RV 11-30 is a size 11 (1.06 inch diameter).
