The latest Eggers PTO brake dynamometer brought to the UK by Lynx Engineering is capable of accurately measuring and verifying the torque, power and performance of tractors and combines up to 735kW/1,000hp.

Believed to be the most powerful of its type in the country, as with other units in the Eggers range, the PT 501 G+ measures torque and rotational speed separately.

The generator, which is used to load the engine, incorporates a hub to measure torque and a speed sensor to record revolutions per minute. Control electronics calculate the performance of the engine under test against the specified power profile.

Lynx is the sole UK importer of the Eggers range from Germany-based KL Maschinenbau, which includes the PT 301 units for full-load curve testing of engines up to 340kW/455hp and 600kW/800hp for rapid testing.

Dealers across the UK and Ireland can either book dyno tests to be conducted by a Lynx technician on the dealer’s premises, or dynamometers can be purchased through Lynx and, if necessary, supported with training.

The software runs on all current Windows-based PCs and laptops, with free updates downloadable online. Data transfer from the test stand to the computer is via the RS232 interface, USB or Bluetooth. PowerControl is also available as an App for Android tablets. All measurements are saved on hard disk and can thus be recalled and printed at any time.

“Testing a tractor or a harvester in summer and then in winter can yield completely different results from the same input data,” explained Lynx managing director, Nick Ewbank, who added that Eggers technology provides a common standard, irrespective of outside air temperature, to give consistently accurate and reliable results whatever the time of year.”

“With this new addition to our Eggers dyno range we can offer our dealers a first-class testing service on any harvester or tractor, saving them a substantial financial outlay on special tools and training which they would otherwise need to support the sales and servicing of the very latest high-horsepower machines.”
