Analog Speed Indicator
 This solid state speed indicator maintains a traditional analog
presentation, yet incorporates the accuracy of microprocessor
control allowing constant display accuracy to be maintained.
It is designed for the harsh and rugged environments of locomotives
and other rail vehicles.
Our analog indicator is interchangeable with the electrical
connections and mounting brackets of older analog models, which
makes this unit a convenient and economical replacement. Available
in base-mount or console mount models.
Options available include a wide variety of speed scales,
an odometer as well as multiple speed controlled relay outputs.
At Bach-Simpson, we offer state-of-the-art products combined
with dependable customer service and customized engineering
support. Remember, when you buy Bach-Simpson, you buy experience,
quality and dependability.
