A function test bench is a system that tests a component under real operating conditions according to predefined parameters. Sensors and instruments are integrated for data collection. The functional test is used to test and simulate the operability of components.
Function Test Rig
media & ambient temperature control
A function test rig is a complete system that controls, measures, and evaluates a DUT (device under test) according to pre-defined parameters. Hence, sensors, instruments, and actuators are integrated into a functional test rig for data acquisition. Typically a function test is used to test the operating functionality of components and simulate whether a part fulfils the predefined features. Poppe + Potthoff Maschinenbau function test rigs enable reliable, repeatable and accurate testing. Consequentially, we tailor our rigs to your requirements and work together to find an ideal solution for your components and test setups.
For example, we offer a functional test rig for testing the power consumption of a battery while attached to the cooling circuit enabling data acquisition under real-life conditions. While applying sinusoidal pressure curves the test rig gathers data for the component designer to optimize the part.
Function test of energy efficiency of the battery during operation
In many EVs, the heating and cooling systems drain the battery and negatively affect the vehicle’s range. Comparing test results before and after a load change test on a function test bench can show how power consumption and performance change over the vehicle’s service life. The test object is connected to the power supply (low voltage 0-20VDC/5A) or high voltage (0-600VDC/150A) and the test media circuit. The test medium is circulated at a temperature of between -35°C to +100°C (-31°F to +212°F) and a flow rate of 1-50 l/min. The test can also be carried out in a climatic chamber at -40°C to +140°C (-40°F to +284°F) simulating changing ambient temperatures such as simulating ice-cold temperatures in Canada during Winter as well as dry heat around the Sahara desert.
We also offer functional tests in various pressure ranges as a service. Whether for research and development or serial production, please contact us with your testing requirements for a non-binding offer.
PRESSURE TEST BENCHES AND APPLICATIONS
PRECISE, REPEATABLE AND RELIABLE
As a specialist in pressure testing technology and state-of-the-art test rigs, Poppe + Potthoff Maschinenbau supports the development and production of particularly resilient components made of various materials – especially for automotive, shipbuilding and mechanical engineering as well as fluid and the medical industry. We offer individually designed test benches such as burst pressure test rigs, pressure cycle test benches, leak test systems, functional test rigs and autofrettage systems.
Pressure change test stand with vacuum testing
Subject cooling systems of ECUs, PTC heaters, high-voltage coolant auxiliary heaters, ACDC and DCDC converters, and other media-carrying components to pressure tests while controlling the ambient and media temperature of, for example, water-glycol at temperatures from -40 °C to 140 °C.
Function test stand: battery simulation under the influence of temperature
For functional testing of media-carrying components, a temperature-controlled volume flow (e.g. 30l/min) can be generated with the Poppe + Potthoff test benches. In addition, a component from e-mobility can be energized if required.
Leakage test stand
Poppe + Potthoff leak test stands can be used to test various components and assemblies for leaks by means of a pressure drop. Depending on the test requirement, our systems can be designed including vacuum unit and low pressure or high pressure module for optimal leak testing. In addition, Poppe + Potthoff offers e.g. bubble tests in a water bath / underwater tests with air and gas.
Compressed air booster
Poppe + Potthoff Maschinenbau GmbH supplies compressor units and pressure control systems up to 400 bar. We offer ready-to-connect units to increase the existing pressure for pneumatic and hydraulic applications. This allows the performance of already existing plants to be expanded flexibly and efficiently.
1050 Bar Helium / Nitrogen / Hydrogen
A leak test bench equipped with a pressure module up to 1050 bar, an optional integrated climate chamber and a gas sniffer (e.g. Inficon) to detect leakage on H2 components such as ontank valves, hoses, pipes, fittings, regulators, valves and fuel cell components.
Household appliance manufacturers are aware of the importance of ensuring that their media-carrying components are leak-proof from day one and that components can withstand a pressure load higher than the operating pressure. Poppe + Potthoff Maschinenbau supports the industry with various pressure testing systems.
