The 0729-1754-99 dual-axis high precision digital inclinometer sensor with RS-485 digital communications is designed and manufactured by Fredericks for use on heavy industrial machinery and other applications where an industrial, robust, cost-efficient solution is needed. This high-precision digital inclinometer sensor has a wide linear angle range and RS-485 communications combined with a small footprint make it simple to integrate into new or existing equipment and designs. The standard version of this inclinometer sensor does not have a housing, so you can integrate it into your board-level design.
The Fredericks Company’s inclinometers take our proven electrolytic tilt sensors and combine them with electrolytic tilt sensor circuits to make inclinometer solutions for use in various markets and applications. Electrolytic tilt sensing technology makes these inclinometers extremely stable with no long-term drift compared to MEMS devices, all in a low-cost inclinometer package.
