Smith 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.

The standard digital sensors are passive sensors with integrated signal conditioning for operation in the 5 to 30 KHz range. Zero speed sensors utilize a special sensing element for operation in the 0 to 20 KHz range and for wide air gaps. Proximity sensors are used for detecting ferrous and non-ferrous metal. The typical operating frequency range for a proximity sensor is 0 to 2 KHz.

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.

Smith Systems, Inc. is a company committed to meeting your unique requirements. We are here to assist with your integration of sensors into end products and systems. Whether the use is in process controls, aircraft gas turbine engines, critical speed controls and braking systems of rail cars, or in remote unmanned pumping and power generating stations. Smith Systems, Inc. can provide cost effective sensor solutions to meet your special application needs with quality and reliability designed into them.
