Sentech Inc
Sentech Inc. is a Willow Grove, Pennsylvania-based manufacturer of LVDTs (Linear Variable Differential Transformers), RVDTs, and a growing line of magnetic motion sensing products — including Hall effect sensors, magnetic pickups, magnetoresistive sensors, and rotary/angular position sensors — acquired through its 2025 purchase of Motion Sensors Inc., a speed sensor manufacturer. The company’s core LVDT and RVDT product line, manufactured under ISO 9001:2015 and AS9100 Rev D certification with ANAB accreditation, serves aerospace and defense, gas and steam turbines, nuclear power, wind energy, oil and gas, and medical markets — with specialty products including FASTAR® fast-acting position sensors and HYDRASTAR® hydraulic-rated sensors, and global safety certifications covering ATEX, IECEx, UL/CSA, CE, and TIIS. The addition of the Motion Sensors product line extends Sentech’s capabilities into magnetic pickup speed sensors, Hall effect switches, and magnetoresistive proximity sensors, making it a more comprehensive position and motion sensing resource for engineers working across the full spectrum of inductive and magnetic sensing technologies.
