About Us

Motion Sensors, Inc (MSI) has been manufacturing speed sensors since 1970.

Our original sensors were developed to meet the extreme temperature cycling, high shock, and vibration demanded by applications in the turbine flowmetering industry. Over the years, our product line and expertise has significantly expanded to include a wide range of speed sensing technologies and industry applications.

Today, MSI provides our customers with world-class engineering and manufacturing capabilities across a variety of industries, including aerospace, rail, military, and power. We develop partnerships with our customers, priding ourselves on the ability to anticipate and adapt to customer requirements quickly and efficiently.

A large part of our success is owed to the adoption of lean manufacturing principles and techniques, allowing the MSI team to provide our customers with high quality product, superior service and unparalleled responsiveness.

Marketing Partners

MSI's ability to understand and meet the unique needs of each customer application is supplemented through strong relationships with our Sales and Marketing Partners.


MSI has recently acquired Ceramawire, a leading manufacturer of high temperature ceramic coated magnet wire. Ceramawire has been a long-time supplier to MSI of wire for use in our High Temperature VR Sensors. Ceramawire's HT Wire is a high temperature magnet wire insulated with a fully cured (1400-1500°F) vitreous enamel film that is firmly bonded to the wire conductor and that assumes the same flexibility and temperature coefficient as the base wire. It is suitable for coil winding and lead wire applications in aerospace, nuclear, steam, chemical, and other high temperature applications. Operating temperature range is -450°F to 1000°F continuous, and up to 1500°F for shorter periods of time. There are also applications that have used the wire successfully to 2000°F. Contact us for additional information.
