Motion Sensors is a small, women owned business. We have been designing and manufacturing speed sensors since 1970 with a primary focus on rail and transit, turbine flow-metering and aerospace appplications. What all of these applications share is a requirment to withstand harsh enviromental conditions including extreme high and low temperatures, high levels of vibration and resistance against intrusion of moisture, grease, oil, etc. Our quality system has been registered to ISO9001 since 2004 and in 2011 we were also registered to the aerospace quality system AS9100. We have our own in-house machine shop and also assemble our own PCB boards in house. Additionally we maintain in-house capability for enviromental testing including shock and vibration and temperature cycling.
