The thesis includes design and making of measuring system for measuring the acoustic properties of induction and electronically commutated fans in company Hidria Rotomatika d.o.o..
The existing measuring system for measuring acoustic characteristics of fans, was inadequate for more detailed analysis of acoustic properties of electronically commutated fans, so it was necessary to design new measuring system. In addition to modular design the new system should be able to control the device under test and autonomous execution of measuring procedure, without the presence of the operator.
In addition to the hardware used, new measuring program was build using Labview programming environment. The new measuring program uses hardware resources to measure the acoustic properties of device under test and produces a measurement report at the end of the measurement procedure, the report is immediately available for analysis.
Functionality of the measuring system was tested using HEC R10R-50LPS fan, short analysis of measured data was later used to confirm proper system operation.
