Smith Systems

Our Company

Smith Systems Inc. is a privately owned manufacturer of speed sensors, motion sensors and temperature sensors, as well as sensor controls, custom instrumentation, and cable harnessing associated with these devices. Our capabilities range from commercial standards (found in assembly and process machinery), to the high reliability sensors used in aerospace applications, to durable products for reliable sensor performance in harsh environments.

We are a qualified source for flight hardware and have supplied products for civilian, military applications and space flight. These products are designed to survive high vibration and extremes of thermal and mechanical shock.

Smith Systems Inc. is a primary supplier of these environmentally protected products to railcar OEMs, transit authorities and private rail operators. Our products monitor axle speed as feedback for anti-skid braking control, PTC journal bearing temperature, fluid and gas temperatures, and other speed inputs for various aspects of train control. These products endure the worst of operating conditions-the underside of a railcar.

We apply all of the rigorous design and manufacturing standards of flight and rail hardware to all our products. When performance and reliability are essential, Smith Systems Inc. can help. We offer many standard devices and will also develop custom solutions for your unique applications.
