Introduction
Congratulations on the acquisition of your new SmartTach Universal
Speed Measurement Tool!
The SmartTach is a precision speed measurement instrument designed
specifically for the development and testing environment. Among its
many innovations is the capability to continuously measure speed form
virtually any type of signal.
The applications for SmartTach are widespread. Engine RPM, Vehicle
Speed and Dynamometer Speed are just a few applications for
SmartTach. Along with measured speed being continuously displayed, a
precision analog voltage output representing measured speed is
available on the Analog output connector. This signal can be connected
to any test-cell computer, data acquisition system, or strip-chart recorder.
This can allow the inclusion of speed measurements among other data
used for transient testing analysis. Three user configurable Range Outputs
are available on the SmartTach. These can be used as warnings to the
dynamometer technician or test cell computer that an engine or test
malfunction may have occurred.
SmartTach is ideally suited as an accessory to any data acquisition or
dynamometer system. It can act as an interface unit allowing engine
RPM or Dyno Speed to be treated exactly the same as any other
measured analog signal. This alleviates the data acquisition system from
difficult high-voltage signal conditioning and high-speed synchronous
pulse processing. It also provides a universal interface for measuring
speed, regardless of the engine specifics.
Installation of the SmartTach is intended to be practical and
straightforward. The compact aluminum enclosure can easily be
mounted in a test cell or vehicle. Microprocessor controlled Intelligent
Signal Conditioning can automatically identify the input signal levels. For
most automotive applications, SmartTach can be connected easily with
the optional TachSensor or Inductive Pickup. This allows unintrusive speed
measurements.
We hope that the SmartTach will provide many helpful solutions for your
engine development and testing needs. Our goal is to provide our
customers with practical solutions that make sense, not simply to sell
products. We want to be on your side when it comes to solving problems.
