Application Note: GL Series Compliance for AMS2750E Data Recorder

Digital Instrumentation / Data Acquisition Instruments Solution for Monitoring and Recording

AMS2750E-Compliant Dataloggers

Graphtec’s current line-up of data loggers adhere to the requirement set forth in the Aerospace Material Specification AMS2750, rev E and are compliant to the AMS2750E requirements. The specification covers pyrometric requirements for thermal processing equipment used in material heat treatment applications. It covers the accuracy requirement and equipment used for temperature uniformity surveys.

Shops that adhere to the standard can confidently heat treat components used in a wide range of aerospace, transportation, and other industries that demand traceable quality procedures for heat treatment.

Graphtec provides a range of recording and reporting solutions for the heat treatment industry that meet the requirements of AMS2750E. Our products provide highly reliable and accurate measurement and electronic recording of heat treatment processes in batch and continuous process operations.

Graphtec paperless electronic recording systems also perform temperature uniformity survey (TUS) work and reporting. Our electronic recording instruments provide far greater recording accuracy and much faster operator access to historical data than paper recorders. Standard network connectivity supports a host of convenience features such as web browser data monitoring, file transfers, and email messaging.

This document will explain how these products comply with the accuracy and temperature uniformity requirements of AMS2750E and it will help you select the best solution for your heat treat application.

Meeting & proving AMS2750E Accuracy Requirements

Graphtec GL series dataloggers meet the measurement accuracy requirements stated in AMS2750E Table 3 for Field Test Instruments. When these models are specified for TUS work and for Nadcap auditing purposes, a calibration certificate and AMS2750E thermocouple accuracy certificate should be ordered with the equipment to prove accuracy.

Instrument Calibration:

The calibration certificate validates the instrument measurement calibration for all supported measurement ranges. NIST and ISO 17025 calibration certificates are available. All calibration work is performed in Graphtec’s California office with partnership with PME Services, Inc. who is a ISO 17025-accredited calibration lab. AMS2750E requires a three-month calibration interval for Field Test Instruments. Equipment can be returned to Graphtec for this purpose or it can be performed by a local accredited calibration lab.

AMS2750E Thermocouple Accuracy Certificate:

To prove thermocouple measurement accuracy for a specific TUS thermocouple type, span and temperature set points, an AMS2750E accuracy certificate can be provided. AMS2750E thermocouple accuracy certificate indicates actual measured performance of set point temperature values input by a precision calibration instrument, using the same thermocouple type and units used in the customer's application. Thermocouple type, units and range must be supplied with the order to obtain this certificate.
