C3 Data’s real-time pyrometry compliance software enables digital uploading of certificate data of all TT Electronics’ thermocouples. TT Electronics is a U.K.-based provider of thermocouples and advanced electronic technologies for performance-critical applications in the heat-treatment industry.
Careful preparation and planning as to how pyrometry requirements should be implemented are essential from a practical perspective, especially for ever-increasing automated and complex multistage, semi-continuous or continuous processes.
In today’s heat-treatment industry, we are faced daily with the challenges of complying with the regulatory standards that are relevant to our specific markets and products.
In a typical multi-burner furnace with numerous temperature measurement points, the change in a single burner’s firing rate can alter the thermal profile inside the furnace in a nonlinear fashion.
Effective immediately, C3 Data’s real-time pyrometry compliance status can directly inform Bluestreak, a heat-treat manufacturing execution system (MES) and quality management system (QMS), whether parts about to be loaded into a specific furnace meet AMS 2750 compliance. This collaboration enables two informational platforms to work in unison, effectively eliminating human-error-prone (manual) processes associated with pyrometry compliance. Since Bluestreak is already used by many heat treaters, operators will have the C3 pyrometry compliance connected to Bluestreak in real-time.
A discovery by Thomas J. Seebeck in 1821 paved the way for the modern thermocouple, and today it is the most widely used electrical sensor in thermometry.
Seebeck discovered that when two dissimilar metals are connected (“junctioned”) together, a minute electric potential will be generated. This phenomenon, known as the Seebeck Effect, is the basis of how a thermocouple functions.
Aerospace Material Specification 2750 (AMS 2750) is the main pyrometry specification that provides the requirements for the calibration and testing of thermal-processing equipment.
The Nadcap® program is an industry-managed approach to conformity assessment that brings together technical experts from both industry and government to establish requirements for accreditation, accredit suppliers and define operational program requirements.
This coordinated Nadcap system results in a standardized approach to quality assurance and a reduction in redundant auditing throughout the aerospace industry.
The COVID-19 pandemic is still ongoing at the time of writing. Terminology we were not familiar with before has entered our vocabulary. Social distancing, shelter-in-place and furlough are now part of our daily lexicon. These are all measures, among others, instituted to protect us.

Just like individuals, each business will have its unique challenges and some commonalities as well. For heat treaters, the need to maintain customer approvals, industry accreditations, equipment calibration and furnace efficiency are vital to their current and future ability to provide heat-treatment services. Yet these are not easy to achieve in optimal conditions, and today’s world is indisputably suboptimal.
Questions about AMS 2750 are common for readers of this journal. We review the impact of this important pyrometry specification to help you deal with the complexities and unknowns in the high-temperature environment of sintering.
Many engineers see CQI-9 as a useful quality checklist that ensures efficient and issue-free processing, while others see it as a burdensome list of requirements that wastes time and money. If the self-assessment document is treated as a box-ticking exercise, it is indeed a waste of resources.
