Thermometrics Completes AS9100 Rev C. Audit
Thermometrics Corporation has successfully completed their audit to AS9100 Revision C. On December, 6 2012, Thermometrics received certification for the Design, Manufacture, Repair and Calibration of Temperature Sensors and Related Hardware for all Industries. AS9100C defines requirements of the Quality Management System for companies involved in Aviation, Aerospace and Defense.
It is a dual certification that meets the requirements of ISO 9001:2008 and approximately 100 additional requirements specific to aerospace product safety and reliability. The certification includes a quality management system focused on areas directly impacting aerospace product safety and reliability, requiring effective product configuration control, product conformance to customer requirements, and product monitoring and measurement for validation.
RTDs vs. Thermocouples
Selecting the right temperature sensors for each application requires a close examination of the requirements.
Imagine you are an instrumentation engineer looking at the prints for a new
plant, and you see the many locations marked out for temperature transducers.
You wonder, what exactly has been specified to fill each space? Thermocouples,
because of the lower cost and familiarity, or RTDs, for the high accuracy and
Temperature transducer selection affects many aspects of the design and
installation of the equipment in the plant such as:
- •The type of wire that needs to be run.
- •The type of instrument that will be in the control room on the other
end of that wire.
- •Whether there will be local junction boxes with terminal strips or
transmitters. And, if so, what type of transmitter is required.
- •Whether any special piping considerations need to be made to install
or protect the sensor or to provide the required response time.
These are just some of the details, and the actual sensor selection and design
has not even been discussed yet. Looking at the big picture can help narrow
down the choices in a logical way. Look first at survival of the sensor and
then the finer points such as any performance requirements
