About

About Jewell Instruments LLC Jewell Instruments has been supplying sensors for driver and driverless metro trains worldwide for nearly half a century. Our sensors are crucial components in safety and control systems providing a safe, controlled ride. Jewell Instruments’ Inertial sensors are part of the multiple sensing technologies that can be found inside many trains or in the trackside infrastructure to ensure a high quality of service. Jewell Instruments’ high performance accelerometers and inclinometers are the heart of demanding train functionalities. Inertial sensors can also be used to monitor passenger comfort or to provide accurate positioning of rail defects when embedded into a diagnostic vehicle operating on rails. Jewell Instruments offers multiple technologies and a wide range of sensors for Rail Applications. Our RailStar branded accelerometers and inclinometers include both high performance Force Balance sensor technology that can be fluid-damped for applications with vibration and shock, as well as MEMs-based sensor technology. Our RailStar line offers high-performance sensors and control products for the rail transportation industry. Many of the products in this line meet CENELEC and AREMA Standards
