The Electrical Contactor Noise qualification system NoiseQ is designed to test, compare and validate the noise generated by the contactor unit. The test system is designed to work in a shop floor environment, with excellent characteristics of external noise isolation, while making the exact measure of noise from the test object, excepting for the loading of the test object into the system, the entire process of measure, average, compare and evaluate the results are automated. The results are logged on to a data base systematically. Using high quality microphones, digital data processing and overall control of the system through microprocessor, we have designed and supplied this systems to users in India and China.
