Tilt Sensors & Inclinometers
JMHI-100/200 Analog MEMS Inclinometer Series
Highlights
The NEW Ruby MEMS inclinometers represent the next generation of high-performance inertial sensors from Jewell Instruments. With an improved Price-Performance, the new Ruby inertial sensors offer improved resolution, faster frequency response, and wider bandwidth — all in a IP67 package that utilizes the same mounting configuration of Jewell’s current MEMS sensors.
Jewell has over 40 years history manufacturing force-balanced sensors and please to provide low-cost high-precision MEMS parts with the same attention to detail that our customers demand.
