ATA-30-12 Alternator Signal Analog Tachometer
ATA-30-12(240).jpg The ATA-30-12 is a rugged, transistorized alternator signal analog tachometer with solid-state circuitry for indication of engine RPM. It is equipped with a bracket for mounting into a standard 3-3/8" (86 mm) dash mounting hole, and has a bright stainless steel bezel.

A full 270° sweep of the pointer gives an accurate indication on a large easy-to-read scale. The dial can be illuminated for night reading. This model is designed to function from pulses generated by an alternator with 4, 8, 12, 14, or 16 poles on the rotor.
