DATA SHEET UNDER REVISION!

Pelton turbine demonstration unit, designed for operation in conjunction with the HM 290 Turbine Service Unit. The turbine unit is placed on the Turbine Service Unit and supplied with water by the service unit. The turbine housing is made of Plexiglass so the tangential water jet can be observed unhindered. A braking device is fitted to the impeller shaft of the turbine, the braking device is in the form of a band brake using which the load and moment on the turbine shaft can be measured with an electronic dynamometer. An inductive proximity switch measures the rotational speed of the turbine. The following accessories are required for operation: an Interface Module (HM 280.01), Data Acquisition Card with Software (HM 280.03) and Set of Connecting Cables (HM 280.04). Using these accessories it is possible to take measurements, and process and store the measurements on a PC.

 
Learning Objectives / Experiments
· Determination of the power output
