Application
It is usually connected with display meter, recording meter and computer, etc. to directly measure temperature
of liquid, vapor, gas and solid surface ranging from 0°C to 1300°C during various production process.
Features
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 results in pyroelectric potential ,then the meter indicates the corresponding temperature to the pyroelectic potential.
