Lynx Engineering, the Irish and UK importer of the German built Egger dynamometers, has added a mobile Eggers 735 KW PT 501 G+ PTO brake dynamometer to its range. According to Lynx, the new import is capable of accurately measuring and verifying the torque, power and performance of engines up to 1,000hp. The firm claims the new dyno could well be the most powerful of its type in Ireland or the UK.
Generator used as braking medium
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. From these measured values, the control electronics calculate the performance of the engine under test against the specified power profile.
According to Lynx, because the generator is used as a braking medium with the sole task of loading the engine and not for power measurement, any potential inaccuracies such as constantly changing efficiencies of the generator are eliminated.
Software
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 RS 232 interface, USB or Bluetooth. PowerControl is also available as an app on Android devices. All measurements are saved on hard disk and can 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. The Eggers technology provides a common standard, irrespective of outside air temperature, to give consistently accurate and reliable results whatever the time of year,” explained Lynx managing director, Nick Ewbank.
This latest addition to the range complements the mobile 600KW PT 301 units which are designed for testing engines up to a maximum of 455hp for full-load curve testing and 800hp for rapid testing. Dealers across Ireland and the UK can now either book dyno tests to be conducted by a Lynx technician on the dealer’s premises, or dynamometers can be purchased through Lynx.
