Thermocouple Brief introduction: The PT100 RTD,thermocouples are used in industry for measuring the temperature of gases,liquids or solid .Its usually assembled with indicators, recorders or computers.A thermocoupleconsists of two dissimilar metals joined together at one end. When the junction of the twometals be cooled or heated and a voltage is produced that can be correlated back to thetemperature. The calibrations are K, N, E.J, T, S, R, B. Each calibration has a different temperature range. Application: It is usually connected with display meter, recording meter and computer, etc. to display measuring temperature of liquid, vapor gas and solid surface ranging from 0ºC to 1300ºC during various production process. Feature: 1. With quick response, reducing dynamic error. 2. Optional installation methods 3. Wide measuring range 4. High mechanical strength, good pressure-resistant performance. Operation theory: The electrodes of armored thermocouple are made of two different materials. The temperature difference between measuring end and reference end result in pyroelectric potential, then the meter indicates the corresponding temperature to the pyroelectric potential.
