TC helps multinational Aerospace Component Manufacturer meet AMS2750 standards

AMS2750 thermocouples in aerospace application

Company Background

A multinational aerospace manufacturer approached us with concerns about failing System Accuracy Tests (SATs) on their heat treatment ovens. These failures had caused their AMS2750-compliant work to stop, leading to significant downtime and additional costs.

Challenges with Temperature Measurement

Despite having an excellent understanding AMS2750 requirements, the company faced two main issues:

System Accuracy Test Failures: SATs frequently failed on two key ovens, causing downtime and labour intensive investigations.
Costly Interruptions: Frequent retests required additional SAT sensors and prolonged the ovens' downtime.
Space Constraints: The existing sensor placement made it difficult to align SAT sensors with primary control and recording sensors.

Ultimately, the manufacturer ceased AMS2750 work with the affected ovens, impacting their capacity and revenue.

Consultation Process

TC conducted an in-depth consultation to understand the challenges and the root cause was identified as:

Misalignment of the SAT sensors with primary control sensors, resulting in inaccurate readings.
Space limitations preventing proper sensor placement near control sensors.

By understanding the oven configuration and AMS2750 requirements, TC devised a practical solution tailored to the client's needs.

Proposed Thermocouple Solution

We recommended our Type 40S Industrial SAT Vacuum Furnace Thermocouples.

Key features included:

Integrated Design: A SAT probe port (1.5mm or 2.0mm) within the same sheath as the control thermocouple.
Precise Placement: Ensured the SAT probe aligned closely with the control thermocouple sensing tip for better accuracy.
Streamlined Installation: A compact design overcame space constraints, eliminating the need for additional oven modifications.

This solution enabled accurate SAT readings, better monitoring of control sensors, and improved oven performance.

Conclusion and Results

The Type 40S thermocouples and new SAT sensors were installed, and subsequent SATs passed without issues. The results included:

Restored Compliance: Both ovens resumed AMS2750 compliant operations.
Increased Capacity: The manufacturer could take on more projects.
Cost Savings: Reduced downtime and labour, avoiding additional equipment modifications.

The tailored solution improved performance and efficiency, increrasing the manufacturer’s capabilities in aerospace heat treatment.

Note: This solution resolved a specific challenge in a particular application. Every situation is different, and your needs may require a different approach. The suitability of any of our products for a particular application is ultimately for the purchaser to determine, as they are best positioned to make that judgment.

These case studies are shared to illustrate how our products have been used successfully, but final product selection should always be based on your specific application requirements, standards, and industry regulations. The suitability of any of our products for a particular application is entirely at the discretion of the purchaser as being the best judge for that particular application.
