Q&A: Klaus-Peter Menzemer, head of product management, Ipetronik | Automotive Testing Technology International

Ahead of Automotive Testing Expo 2022 in Novi, Michigan, Ipetronik’s head of product management, Klaus-Peter Menzemer, gives an insight it the creation of its next-gen temperature measurement technology.

Describe Ipetronik and its core automotive testing expertise.Ipetronik has developed modular measurement technology for more than 30 years. Beginning with SIM-Devices (separated integrated measurement devices), it is now developing the third generation of M-Devices (mini devices), starting with the M-Thermo3 16. Ipetronik also offer datalogging units and software (IPEmotion); both now have their own product lines. It provides engineering services tailored toward thermal management, including testing facilities and test benches.

What are the key features of the new M-Thermo3 16 temperature measurement module?Accuracy, reproducibility, usability and user-friendliness. As space during testing is limited, we reduced volume and weight by 30% compared to previous M-Devices: the interconnection cable was removed; by eliminating this potential error source, system handling and comfort are improved, alongside process safety. Sustainability was prioritized through lower power consumption and a material-optimized manufacturing process.

Why modular?The modular concept is a cost-saving factor – sensor wires are short and replaced frequently, enabling sustainability. Setups easily use 200 temperature channels or more, routed to a 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 cable per vehicle. Less cabling means less effect on the unit under test. Using Ipetronik, openings stay open with fewer or smaller cable run-throughs.

Modular concepts enable the best system utilization with setups easily adjusted to the measurement task. High-channel, one-box systems have huge disadvantages including many unused channels for small tests or adjustments if the required channels exceed the available channel count. We want our solutions to adapt to test requirements.

How does the M-Thermo3 16 save time during installation?The M-Thermo3 16 focuses on process safety and time optimization during test setup. We engineered a tool-less, reliable, mechanical connection and optimized the manufacturing process in our magnetic mounting feature. We also developed a technology establishing both the electrical and mechanical connection; removing cable connections saves costs and eliminates the risk of bad connections.

What applications can you test with the new M-Thermo3 16 – is it relevant to AVs, for example?It is relevant for every application requiring accurate thermocouple readings, such as brake testing. For AVs, thermal management systems are the most complex in the field; if ECUs overheat, the vehicle will stop operation. The same is true for drivetrain systems, including batteries. Thermal management has evolved from comfort to safety.

Any other features of note?Our customers need accurate thermocouple readings to design and develop high-end thermal management systems. The new M-Thermo3 16 combines ruggedness and accuracy with a special thermocouple socket, ensuring that it works every time no matter the condition, anywhere in the world.
