RTD quick thermal response Small diameter High measuring accuracy high reliability and stability

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.Features1.With quick response, reducing dynamic error;

2.Optional installation methods;

3.Wide measuring range ;4.High mechanical strength, good pressure-resistant performanceOperation theoryThe 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.Mail technical parametersExecutive standard:IEC584IEC1515GB/T16839-1997JB/T5582-91
