Nadcap

Nadcap is the leading worldwide cooperative program of major companies designed to manage a cost effective consensus approach to special processes and products and provide continual improvement within the aerospace industry.

AMS2750D describes the pyrometric requirements for thermal processing equipment used for heat treatment. There are many requirements surrounding SAT (System Accuracy Test) and TUS (Temperature Uniformity Survey) and the frequency that they have to be carried out.

Yokogawa can provide a full range of products including software solutions for SAT, TUS testing and the furnace instrumentation fulfilling the requirements of AMS2750D. Our long term contribution to temperature monitoring and controlling ensures accurate and reliable furnace operation.

All-purpose recorder for TUS, SAT & process recording. TUS Reporting Tool ready to minimize your report work.

Automatic reporting tool produces a comprehensive fully formatted document in-line with the requirements of AMS2750D. The report takes minutes to generate, compared to the hours of work needed to produce the report manually.

• Produces a report based on a number of files from a DXP/DX/DXAdvanced from its binary data files. No manipulation.
• Produces Test Data sheet showing all of the test details
• Test Overview gives
• Min/max data per test per T/C (last 30 – 120 minutes)
• Maximum overshoot of test per test per T/C
• Maximum deviation of min/max/overshoot per test + which T/C
• Pass/Fail based on the uniformity
• Time taken for 1st T/C in specification to last T/C in specification
• Out of spec low blue font out of spec high red font
• Caters for number of T/C's and number of tests performed
• User can add template e.g., furnace layout filled in by the report
• Auto formats each page ready to be printed out

AdvancedReport is a software tool for creating customised reports. Utilising original binary data files from the Daqstation^® recorders, reports are generated based on user templates. Reports are created in minutes.

• Produces a report based on a number of files from a DXP/DX/DXAdvanced from its binary data files. No manipulation.
• Supports both automatic and manual conversion.
• Automatic conversion
  Periodically check the target folder, and generate reports from new data files.
• Manual conversion
  Users select target data files manually to generate reports.
• Users can create templates to produce customized layouts.
