How to Minimize Thermocouple to Transmitter Measurement Errors - 8500926 (Log in to view the file)Preventing Temperature Measurement Error in Thermocouple to Transmitter Connections The nature of thermocouple (TC) circuits is that they’re prone to produce error when mating them to a measurement device; unless you have some insight into how these TCs and their components work. This paper reviews thermocouple behavior and outlines common problems encountered when connecting them...How to use Thermocouples for Temperature Measurement - 8500911 (Log in to view the file)Criteria for Temperature Selection of T/C and RTD Sensor Types This is part two of a comprehensive three-part series that provides information for choosing an industrial temperature sensor from Thermocouple (T/C) and Resistance Temperature Detector (RTD) sensor types. The Basics of Temperature Measurement Using Thermocouples You are probably somewhat familiar with the thermocouple, or... -
