Eddy Current Dynamometer
EC Series
Specifically designed for small displacement diesel engines, the Eddy Current (EC-Series) engine dynamometer features in-line eddy current absorption units in a robust, compact frame. The air-cooled eddy current absorbers eliminate the need for an expensive water recirculation system and most engines being tested can be cooled with a standard closed-circuit radiator system. This compact air-cooled design results in a minimal environmental impact and the ability to be easily relocated with no need for a permanent installation. When combined with PowerNet LT, our fully automated dynamometer control system, all of your testing needs can be performed at the touch of a button.

Preamplifiers
A.H. Systems'' Preamplifier line is an excellent choice with a rugged design, no hassles with soldering your own power leads and they improve overall system sensitivity by at least 20 dB. All of A.H. Systems'' Preamplifiers come with a 12-volt (or 15-volt) DC regulated power source. A low voltage indicator confidently allows you to power the amplifier with your own external 12-volt DC battery. This makes it a convenient choice for field measurements. See table below for amplifier specifications.
