Speed Indication & Sensing

Speed Indicators provide an accurate speed display at an economical cost. Available with Digital or Analog displays in both a panel and base-mount enclosure. Each maintains the reliability and rugged performance customers expect.

The Odometer unit displays total distance accumulated (in either direction) by a vehicle. This information is presented on an 8 Digit Display and can be communicated to the vehicle’s central diagnostic system.

Doppler Speed Sensor is a reliable and field-service-proven system with no moving parts. The sensor is mounted under the vehicle and determines the vehicle speed via a low power microwave signal. This signal is processed to provide an accurate, true ground speed reading. The Doppler Speed Sensor's output is compatible with existing speed indicators and event recorders. The sensor is mounted and wired independently from the truck to simplify routine truck maintenance tasks, and, with no connection to the vehicle axle, there is no need for wheel size adjustments. Its ease of application and strong operational features make this speed-sensing system as useful as it is cost effective.

The Axle Alternator is designed to translate the rotational speed of a locomotive or transit vehicle wheel and axle into an electrical signal, which represents the linear ground speed of the conveyance. The Axle Alternator is mounted on the locomotive or car truck journal box by means of an adapter and is driven by the axle through a flexible connector or pegbar. The signal produced can be used by speed-actuated devices such as locomotive speed indicators, event recorders and transition controls.
