Custom Digital Speed and Active Speed Sensors

Smith Systems Digi-Tran ® Digital Speed Sensors utilize integral active signal conditioning electronics to provide constant amplitude output regardless of exciter speed. These speed sensors can be powered with a wide range of supply voltages and are compatible with digital equipment. These speed sensors can be used to detect ferrous metal and magnets in motion. Smith Systems, Inc. offers three types of active speed sensors, standard digital, zero speed, and proximity.

Smith Systems, Inc features 3 types of active speed sensors:

• Standard Digital Speed Sensor
• Zero Speed Sensors
• Proximity Speed Sensors

About Smith Systems, Inc.

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