Industrial Thermocouple 4-20ma Pt100 Temperature Transmitter Sensor
Industrial Thermocouple 4-20ma Pt100 Temperature Transmitter Sensor Description:
Industrial Thermocouple 4-20ma Pt100 Temperature Transmitter as a measurement of the temperature sensor, Usually, and display instruments, recording instruments and electronic supporting the use of regulator. It can be directly measured in various production processes From -20℃~500℃range of liquid, steam and gas and solid medium surface temperature.
According to the provisions of the state, Our company in line with the IEC international standard index number Pt100 platinum thermal resistance And in accordance with the professional standards index number Cu50 thermal resistance two categories two kinds of assembly type, unified design thermal resistance.
Industrial Thermocouple 4-20ma Pt100 Temperature Transmitter Sensor Working Principle:
Thermal transmitter is when the temperature changes its resistance along with the characteristic changes of temperature measurement using the material. The thermal resistance of the heating part (temperature sensor) is made of metal wire even double wound on the insulating material on the skeleton. When measured in the medium temperature gradient exists, The average temperature of the measured temperature is the temperature of the components within the dielectric layer in the.
Assembly type thermal resistance is mainly composed of a junction box, protection tube, terminals, the insulating casing and the temperature sensing element is the basic structure, And with a variety of mounting and fixing device.
The temperature sensing element NT platinum thermal resistance is a platinum wire winding, Double platinum resistance is mainly used to detect the same place temperature occasions with two sets of display, recording or regulator.
