Sherborne Sensors Ltd. can be traced back to 1945, with the formation of Schaevitz Engineering; a US-based manufacturer of LVDTs and other precision sensors. After nearly three decades of success, Schaevitz Engineering began manufacturing inertial products in the UK in 1974. In 2007, Sherborne Sensors extended its product range beyond inertial sensors by obtaining the former Maywood Instruments force transducer product lines and intellectual property. Sherborne Sensors has since extended its operation further, establishing a sales and stocking location in North America in 2009. As we approach the 40th year of production of Schaevitz® inertial sensor products in the UK, and the 34th year of production of Maywood force products, Sherborne Sensors continues the legacy of cost-effectively manufacturing its products to the highest quality and performance standards in the industry.
