- How to Design a Reliable, Efficient Leak Test for Temperature Sensors

[innomatec Staff](https://blog.innomatec.com/author/innomatec-staff) 01/28/2025

 2 Minutes

Sensors play a critical role in a wide range of industries, including automotive, EV, HVAC, household products, and more. Whether they are temperature sensors, fuel sensors, pressure sensors, position sensors, or airflow sensors, these components are essential for ensuring the proper and safe operation of assemblies and products in real-world conditions.

 

innomatec recently worked with a leading automotive manufacturer to design a leak test for sensors housed within a new type of electric motor. There were two types of sensors; a static temperature sensor and an oil temperature sensor. They required reliable leak testing to ensure optimal performance and safety in the field. Defective sensors could lead to serious issues, such as overheating, electrical shorts, and oil spills, compromising the motor's functionality and safety.

 

Faced with higher-than-anticipated demand, the manufacturer was also under pressure to meet high throughput goals. They needed a leak test system that would be fast, but also provide the most accurate leak test to ensure product qualityfor their customer.

 

**The answer? Automation!**

Designing a flexible, semi-automated turnkey leak test system for two different part designs using innomatec’s LTC-902 Twin leak tester

innomatec designed a semi-automated turnkey leak test system to deliver the efficiency and accuracy the manufacturer required for this application. Using this innovative machine design, operator would load and unload the parts into a fixture, with the rest of the process being automated to make a faster processing time possible.

 

To accommodate testing two different part designs on one machine, the test was built with exchangeable fixtures (complying with SMED guidelines of \<15min) and an identification system built into the bench to ensure the correct test settings as each new batch of parts was scanned into the system.

Ensuring a reliable sensor leak test and exceeding manufacturer’s goals

Using innomatec’s semi-automated leak test system, the manufacturer was able to test parts at a rate of less than 20 seconds per part—meeting and exceeding their throughput goals!

 

Due to the flexibility of the machine design and the LTC leak tester platform, the manufacturer is also now in a position where they could use the same machine design for different parts as their production evolved and scaled, requiring only simple changes in fixturing.
