Sigma DYnamometer Intelligent hand-held terminal (IHT)

Sigma Dynamometer Intelligent hand-held terminal (IHT)

Housed in a robust industrial polycarbonate and polyamide enclosure with IP65 protection, membrane keyboard and back-lit graphic LCD. The IHT allows remote working whilst still having live display information and control of the five test modes and gives information of high idle speed, maximum torque and torque rise.

Automatic Test

This allows the dynamometer to run a consistent test across a full power curve. It allows the operator to focus on the test and not the equipment. Full accuracy is assured and the whole test is completed in a few minutes, saving time, eliminating operator error and provides reliable, repeatable test results with a full summary displayed on the screen.

Constant Speed

Set a speed and the SIGMA control system adjusts the load until the required speed is reached, then it will be maintained even as auxiliary loads change. You can measure power at nominal PTO speed or at rated engine RPM.

Constant Power

Simulate working conditions by selecting any power value of your choice that the engine on test can achieve and the SIGMA control will endeavour to maintain this power irrespective of engine speed.

Direct Load

Manually apply and remove load by pressing the ‘+’ or ‘-‘ keys. The braking force is set directly for warming up or bedding-in an engine prior to a full performance test.


Pre-set and then apply a sudden step load change to check for governor response, instability or clutch slippage.

Help when you need it

The user HELP feature guides the operator if required, and the screen can be set to display in any one of four major European languages. Readouts can be in metric or imperial units.

For graphical displays, report making, excel export functions, warm-up capabilities and many other advanced features, why not consider the DynaTest dynamometer PC software.
