RVDTs provide an extremely reliable measurement solution for precision rotational position displacement (position) measurements in aviation, and many other markets. The RVDTs non contacting feature ensures high reliability and repeatability for angular displacement transducer measurements. RVDTs are used wherever angular position feedback is required for position monitoring or as part of a closed loop control system. The construction of the RVDT sensor prevents direct contact between the moving and the stationary part. The result is long operational life.

Sentech has offered rotary displacement transducer with or without shaft bearings across the globe for 30+ years. The sensor measures 0.75” to 1.50″ in outside diameter. The mounting can be a standard servo mount  Size 8, 11, 15 servo mount. Angular position sensor measurement range is ±70 degrees (140°). The mechanical range is a full 360 degrees.

Sentech provides industry standard units or we can customize an aerospace RVDT transducer with a cost-effective solution for your application. Select either DC/DC RVDT (with integral electronics) or AC/AC RVDT. AC/AC RVDTs require signal conditioners to power the sensor and provide a DC output. Sentech has signal conditioners for your needs. When it comes to RVDT sensors our rotary variable differential transducer will also work with most of the commonly available LVDT/RVDT signal conditioner. In addition, we make dual, redundant RVDTs and/or certified Intrinsically Safe or Non-Incendive protection for Hazardous Environments. RVDTs offer a reliable solution for severe environment applications.
