IPETRONIK
What A device or an appliance to test an objects technical
characteristics in repeatable manner Test benches include
Preparation and maintaining of test conditions such as temperature, humidity, mass flow
Mechanical device to integrate the test object Machinery, sensors and control system
to provide and maintain above mentioned conditions as well as to log measured valuesand create test reports

IPETRONIK
How Test benches need to provide a wide range of changes
in temperature and humidity, e.g. from -40°C to +100°C in 2hrs stress test in time-lapse effect
Constant monitoring of functionality + performance of components / system
All kinds of media like cooling water, refrigerant fluid, engine oil, transmission oil, exhaust, .. are provided by test bench
Requires robustness of test bench itself and long expertise of test bench design
Process intelligence transferred into bench by customized PLC programs and operating software IPEtec test benches
