AIR46B - The Preparation and Use of Chromel-Alumel Thermocouples for Aircraft Gas Turbine Engines

Details
Document Number: AIR46B
Revision Number: B
Title
The Preparation and Use of Chromel-Alumel Thermocouples for Aircraft Gas Turbine Engines
Scope
This SAE Aerospace Information Report (AIR) reviews the precautions which must be taken and the corrections which must be evaluated and applied if the experimental error in measuring the temperature of a hot gas stream with a thermocouple is to be kept to a practicable minimum. Discussions will focus on Type K thermocouples. These are defined in NBS Monograph 125 as nickel-chromium alloy versus nickel-aluminum alloy thermocouples.
