температура

temperature sensor,temperature sender -High mechanical strength -Good pressure-resistant performance -High precision 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 to 1800 during various production process Features With quick response, reducing dynamic error Optional installation methods Wide measuring range 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.
