Temperature Uniformity Profiler Progress Update

Dealing with Dated Technology

AMS (Aerospace Material Specifications) 2750 Rev F is an international aerospace specification which covers the pyrometric requirements for equipment used for the thermal processing of metallic materials. Among the many changes between Rev E (July 2012 publication) and Rev F (June 2020) the most noticeable requirement is for all digital measuring instruments to have 0.1° resolution.

This made many of the existing instruments on the market non-compliant for aerospace use and therefore obsolete. It became necessary to have instruments capable of more precision measurements guaranteeing a more accurate Uncertainty of Measurement when measuring to the millionth of a Volt (µV). AMS 2750 Rev F requires Field Test Instruments to have only a ±1.0°F or 0.1% of reading (whichever is greater) tolerance interval for calibration.

Engineering a Solution

Powered Engineering was offered the opportunity to develop such a precise electronic measurement devise for the purpose of Temperature Uniformity Surveys (TUS) for aerospace heat treating process’. The result is the TUS Profiler.

The Profiler is a standalone device that was designed for use in extreme factory conditions. Coupling high precision components with next generation programming, the product that Powered Engineering delivered is capable of measuring to the billionth of a Volt (ηV) resolution, well exceeding the new AMS 2750 Rev F requirements. Using up to 16 thermocouples of any type, on any channel, at any time the Profiler employs open circuit detection, captures data as fast as once per second, and automatically builds the report during the survey including automatic pass/fail detection.
