Thin-film tilt sensor cuts cost but not accuracy The new tilt sensor from The Fredericks Co., Huntingdon Valley, Pa. (www.frederickscom.com), uses thin-film electrodes to detect angles of ±30 arc-min within less than 0.05 arc-sec of resolution and 0.5 arc-sec of repeatability at null, exceeding the performance of MEMS tilt sensor, according to the company. And using thin-film electrodes reduces costs compared to other high-accuracy tilt sensors. The hermetic housing — a glass vial — ensures a long operating life in extreme operating conditions.
