This new EGGERS dynamometer is produced by the manufacturer of the already well-known EGGERS dynamometer: KL-Maschinenbau. Like all other test benches of the manufacturer, it is designed and manufactured in Rendsburg.
A generator as braking mediumIn general, the new EGGERS dynamometer works like the proven models on the principle that both - the torque and the rotational speed are measured separately. The generator used to load the engine is therefore provided with a torque measuring hub. This torque measuring hub measures the resulting Torque, a speed sensor senses the revolutions per minute. From these exactly measured values, the control electronics calculates the performance of the test object according to the power formula*. Inaccuracy factors such as constantly changing efficiencies of the generator are eliminated, because this brake medium has only the task to load the engine – but is basically not used for power measurement. This measurement method is physically sound and internationally recognized.
Like all other EGGERS Dynamometers, also the model PT 501 G is calibratable. The time required for this is very low and can be performed expertly by the user.
To achieve a high endurance load, in this new model an electric generator is used as braking medium. The generated electricity is converted into heat by means of heavily dimensioned high-power resistors. The very high continuous braking power of the new EGGERS Dynamometer remains constant and does not decrease at all. The new EGGERS dynamometer can be shut down without aftercoolin – immediatly after the test (hot shut down).
