Mustang Dynamometer >>> Engine RPM Module

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 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 Optical or Inductive Pickup which are included standard with every unit.
