Ahead of Automotive Testing Expo 2022 in Novi, Michigan, Ipetronik’s Head of Product Management Klaus-Peter Menzemer provides insight into the creation of its next-generation temperature measurement technology.
Describe Ipetronik and its core automotive testing expertise.
Ipetronik has been developing modular measurement technology for over 30 years. Starting with SIM-Devices (separate integrated measuring devices), it is now developing the third generation of M-Devices (mini-devices), starting with the M-Thermo3 16. Ipetronik also offers data logging units and software (IPEmotion); both now have their own product lines. It provides engineering services suitable for thermal management, including test facilities and test benches.

What are the main features of the new M-Thermo3 16 temperature measurement module?
Accuracy, reproducibility, usability and user-friendliness. As space during testing is limited, we have reduced the volume and weight by 30% compared to previous M-Devices: the interconnect cable has been removed; by eliminating this potential source of error, the handling and comfort of the system are improved, as well as the safety of the process. Sustainability was prioritized through reduced energy consumption and a material-optimized manufacturing process.
The modular concept is a cost-saving factor – sensor wires are short and replaced frequently, allowing for durability. Setups easily use 200 or more temperature channels routed to trunk space requiring 4m per channel or 800m of thermocouple wire. A modular distributed system reduces wires to 1m per sensor, saving customers 75% of thermocouple wire per vehicle. Less wiring means less effect on the unit under test. With Ipetronik, the openings remain open with fewer or fewer cable runs.
Modular concepts allow the best use of the system with configurations easily adjusted to the measurement task. Monoblock systems with high channels have huge disadvantages, including many unused channels for small tests or adjustments if the channels required exceed the number of channels available. We want our solutions to adapt to testing requirements.
How does the M-Thermo3 16 save time during installation?
The M-Thermo3 16 focuses on process safety and time optimization when setting up tests. We have designed a reliable, tool-less mechanical connection and optimized the manufacturing process in our magnetic mounting feature. We have also developed technology that establishes both the electrical and mechanical connection; eliminating cable connections reduces costs and eliminates the risk of bad connections.
What applications can you test with the new M-Thermo3 16? Is it relevant for AVs, for example?
It is relevant for all applications requiring accurate thermocouple readings, such as brake testing. For AVs, thermal management systems are the most complex in the field; if the ECUs overheat, the vehicle will stop working. The same goes for transmission systems, including batteries. Thermal management has evolved from comfort to safety.
Other features worth noting?
Our customers need accurate thermocouple readings to design and develop high-end thermal management systems. The new M-Thermo3 16 combines ruggedness and precision with a special thermocouple socket, ensuring it performs every time, in any condition, anywhere in the world.
