Temperature Uniformity Survey (TUS)

AMS 2750E is the current governing pyrometry specification in the thermal-processing industry. It covers temperature sensors, instrumentation, thermal processing equipment, system accuracy tests, and temperature uniformity surveys (TUS). These are necessary to ensure that parts or raw materials are heat treated in accordance with the applicable specification.

Yokogawa's TUS software meets the rigorous requirement of AMS2750E standards. Combined with Yokogawa's accurate and reliable data acquisition system, end users can easily perform temperature uniformity surveys. Based on the stability criteria and survey measurement, the software algorithm will automatically determine the survey result and generate a printable report that can be used for audit and data analysis. In addition, software allows users to save multiple profiles.

Intuitive UI

TUS Navigation PaneYokogawa TUS's intuitive navigational panel guides users through the steps of creating a TUS report. The 2 level tabular navigational layout makes it easy to navigate and the dialogue window prompts the users for required information. Users have the flexibility to drill down to any tabs in the navigational panel at any time.

Profiles

Users can create and save specific profiles for each furnace under profile management. All information entered in any section of the dialogue window will be saved. If a TUS survey shares similar meta-data information as a previous TUS survey, user can load the previous TUS survey profile and save it under a new profile. This feature saves time by preventing redundant data entry.

Calibration Correction

Instrumentation

Instrumentation calibration correction value can be retrieved automatically from the software via the recorder's data files. If required, the instrumentation calibration correction value can be entered manually. Additionally, raw data (control) and corrected data (survey) can be shown seperately on the report.

TUS Instrumentation

Thermocouple

Thermocouple calibration value can be entered manually in the software.

Report

The report is broken into 6 sections

  1. Metadata Information
  2. Summary Table
  3. Furnace Information
  4. Overview Data Trend
  5. Setpoint Data Trend
  6. Raw Process Data

The report also allows users to edit the header and footer of the report template to include individual company logo, information and comments. Furthermore, the report allows users to import up to 6 images of the vacuum furnace.

Overview:

Temperature Uniformity Survey (TUS) is a vital part of the overall equipment performance and validation that ensures the heat treat/vacuum furnace repeatedly and accurately produces the same quality parts with no variance. Based upon the furnace class and its specifications, the equipment must hold uniform temperature across all zones at a specified set point and time-period, according to SAE AMS2750E pyrometry standards.
