TECHNICAL DETAILS
The analogue output data is digitised and transferred to a computer using the standard USB (Universal Serial Bus). This allows any standard modern Windows computer to be used, including notebooks, and does not require any internal access to the computer.
The equipment is supplied complete with a USB lead for connection to the computer. The FM 16 Turbine Demonstration Unit interfaces to the computer via the provided devices and the USB port of the computer. Also available is a software driver that allows the outputs to be read in other software programs, such as Labview.
1. 3- ph. electrical supply, 440 V, 50 Hz.
2. Water supply and drainage.
