Efficient performance tests for household appliances: the importance of household appliance test stands
Household appliance test stands are special devices used to test the performance and safety of household appliances. The testing of household appliances is essentially carried out under the following aspects: Operator safety, energy efficiency, quality and reliability. Standards and test specifications form the basis for many testing tasks. Standard-compliant tests in particular offer a high potential for automation. In addition, it is important that the test stand for household appliances has accurate measurement technology to objectively assess the appliance's performance. This includes the measurement of energy consumption, volume development and other relevant parameters. Last but not least, the household appliance test stand must also take into account the safety aspect and minimize possible risks during the test.
The software ProfiSignal Klicks is in connection with the ProfiMessage or the Expert Key devices is an ideal combination for testing household appliances. Above all, the consistent galvanic isolation and the flexibility of the inputs as well as the simple creation of test procedures and sequences enable the user to implement the test specifications for various household appliances efficiently and independently.
Application highlights of the household appliance test stands
- Universal inputs suitable for all common sensor types (Pt100(0), thermocouples, mA, mV)
- Continuous galvanic isolation of all inputs
- Complete solution comprising hardware and user-friendly software for domestic appliance test stands
- Easily adaptable to the respective testing task and expandable at any time
- Easy integration of precise power meters (e.g. ZES Zimmer)
Practical example of a household appliance test stand
Automated testing of high-quality household appliances
In addition to various development laboratories, a manufacturer of high-quality household appliances also operates a test laboratory for reliability testing of stoves, extractor hoods and ovens during series production. As new testing and automation tasks are constantly arising, the requirements must be implemented independently by the laboratory staff. The self-sufficient ProfiMessage devices form the hardware basis for reliable long-term operation. All control tasks are implemented by the integrated software channels in the ProfiMessage devices. The clear display of the various test tasks, the display of results and status information as well as long-term archiving is carried out using the ProfiSignal implemented.
