Single Tachometer 6503 Series

6503 Tachometers

 

The INSCO 6503A series of single tachometers are servoed replacements for "drag magnet" tachometers. These beautifully designed and updated tachometers really perform. With greater accuracy, smoother operation and elimination of friction and position errors, the 6503A series offers maximum reliability. In fact, many INSCO 6503A series tachometers have been in daily service in 1972, and today's design is greatly inspired from that of the earlier instruments.

SPECIFICATIONS:
The 6503A operates from either a standard 2 or 4 pole tachometer generator, or from a magnetic pulse (monopole) transmitter. The indicator is entirely self-contained, requiring only 28 volts DC power, and a frequency (speed) input).

It is available with or without a Vernier pointer, and has specified accuracy of + / - 0.5% F.S. It is also available with an overspeed or underspeed warning lamp on the dial, and connector contacts for remote warning functions.

The 6503A has been designed with maximum reliability in mind. There are no punched gears or bushings in an INSCO gearhead. We use precision machined close-tolerance aluminum and stainless steel gearing, and every gear shaft runs in ABEC7P miniature bearings. All electronic components are selected with a wide 'cushion' to prevent premature failure, and much of the circuitry is hybridized into a custom thick-film circuit.
