Standards such as the AMS E (Aerospace Material Specifications) are applicable for the industrial processing of high-quality materials. They define. 8 Mar The AMS specification establishes the requirements for controlling thermocouple usage. There are very specific (some might say. Yokogawa provides a range of recording, reporting, and control solutions for the heat treatment industry that meet the requirements of AMSE. Our products.

Good sensor measurements set the stage for good process control with repeatable results — a good formula for staying in business. It continues to evolve and fractionate into different Aerospace niches. To illustrate the different sensitivities of different thermocouple types, please see the graphics below.

In general, we must first understand the differences between Aerospace Materials Specifications AMS E and Nadcap certification from a topical view. Understanding of the specifications and requirements set out by AMS E and Nadcap that pertain to your processes will help to simplify certification.

The different levels of instruments are classified as follows: The first edition of CQI-9 was published in Who is it for? The full range of advanced capabilities and convenience features of both products are made available to support the application- precision control functions are handled by the UTAdvanced, and all display, operator interface, recording and network data access functions are handled by the GX.

The thoughts behind this relate to the production parts: The AMSE standard specifies the thermocouple sensors to be used, as well as the sensor wire types. Customers that are new to the aluminum brazing arena are often taken aback by the condition of the hot zone and furnace after a few short months of operation. A recent study indicated aside from job audit non-conformance reports NCReight of the top ten NCR causes are related to pyrometry.


Ams2750r should be performed periodically or after any maintenance. The furnace you choose must be amw2750e to achieve the necessary requirements for the parts you are processing to ensure compliance is achievable. When selecting a furnace for aerospace aluminum brazing consider the following: But the same standards and processing techniques can be used within any industry which requires control of the thermal processing of raw materials and manufactured components, such as automotive, rail and manufacturing.

Voted best recorder 10 straight years in a row! As mentioned, the AMSE is a standard for the heat treatment.

With possible additional adherence to: As can be seen below leftwhen defining furnace class the definition is determined by the temperature uniformity required within the working zone. AMSE is somewhat a complex document and for many clients who are maybe new to the industry, some of the details and procedures may seem to be a little onerous when applied to everyday processes. And as the Centigrade and Fahrenheit are different, below is a graph of both for your convenience: Figure 1 shows an internal view of a aluminum vacuum brazing furnace.

SAT is a simple test performed in order to determine that the thermocouples and instruments are giving an accurate depiction of temperature.

AMSE Heat Treatment Standard and Calibration

More details about CQI-9 maybe in an other post later on Panel mount and portable models are available and all include universal inputs that measure a wide range of thermocouple and RTD temperature sensor types, plus DCV, mA, and DI process inputs.

Alternatively, the recording instrument may be connected to a second sensor contained in the same sheath or holder as the control sensor, and separated from the control sensor by no more than 10mm X X X X At least two additional recording sensors in each control zone shall be located to best represent the coldest and hottest temperatures based on the results from the most recent temperature uniformity survey.


For each instrument class, there are specifications for the calibration period and calibration accuracy. Therefore, very tight control and documentation of the heat treatment process is essential to assure the quality of the end products.

Data Acquisition Stations These all-in-one measurement, display, and electronic recording systems are the ideal upgrade solution for a fully AMSE- compliant batch or continuous process recording system. Types of thermocouple sensors to be used, the use for thermocouples primary calibration, secondary calibration, sensor calibration, TUS, SAT, installation, load sensingcalibration period for thermocouples, and maximum permitted error.

Nadcap AMS2750E and CQI-9 compliance

Thermal processing equipment 3. While the results and success of some other industrial processes can be relatively easily measured after the process, this is not the case in a heat treatment process. An initial TUS needs to as2750e performed for any new, modified example modifications are listed in the standard or repaired furnace, and thereafter it should be performed in accordance with the interval specified in the standard.

Each control zone shall have over temperature protection. During production in multi zone furnaces, empty zones do not require a load sensor. AMS E Vacuum Specifications There seems to be a bit of confusion in the area of AMS E as it relates to vacuum processes, so it is worth delving into this topic in order to reach a better, more thorough understanding. While many claim to be AMS E compliant, there are ams22750e several different versions that constitute a,s2750e in regards to vacuum heat treatment systems.
