PT100 round plug type armored thermal resistance1

Pt100 round plug type sheathed the temperature of the thermal resistance is a common measuring instrument, it has high precision, good sensitivity, fast response time, stable quality, long service life, etc. Today engineering mainly introduce round plug type sheathed basic working knowledge of thermal resistance, hope you can help to you.

pt100 round plug type armored thermal resistance overview

round plug type armored thermal resistance to - 200 ~ 600 ℃ temperature range of gas and liquid medium to automatically detect and solid surface, and can be directly connected with copper wires and secondary instrument use, because it has good electrical output characteristics, to display, data recorder, recorder, controller, scanner and computer to provide accurate input values.

pt100 round plug type armored thermal resistance characteristics of

armoured resistors external protecting tube of stainless steel, full of high-density oxide material inside insulation, so it has a strong pollution resistance and excellent mechanical strength, suitable for installation in harsh environment. Armored thermal resistance usually by armoured platinum thermal resistance temperature sensing element, install fixtures and wiring devices and other major parts, such as thermal response time, reduce the dynamic error; Small diameter, length is not restricted;

high measuring accuracy;

imported film resistance element, performance stable and reliable;

round plug type armored thermal resistance measurement range

element thermal resistance temperature 100 ℃ when the resistance value of ( R100中) And it is in 0 ℃ when the resistance ratio (R0 R100R0)

dividing Pt100: grade A R0 = 100 + 006 Ω

B R0 = 100 + 012 Ω

R0R100 = 13850

Pt100 round plug type sheathed working principle of the thermal resistor

armored thermal resistance is to use the material when the temperature changes, its resistance also along with the change of characteristics to measure temperature. When resistance changes, the work shows the temperature resistance of the meter. Armored thermal resistor is a kind of temperature sensor, it is smaller than the diameter of a prefabricated thermal resistance, flexible, good vibration resistance, suitable for installation in place of prefabricated thermal resistance can't install.

armored thermal resistance protective mining have stainless steel, with high density in oxidation material insulation, therefore, armored thermal resistance strong pollution resistance and mechanical strength, suitable for installation in harsh environment.

pt100 round plug type armored thermal resistance to install and use the

resistance should avoid too close to or from the heating body installed on the stove, should try to install where no vibration or vibration is very small, at the same time to facilitate the construction and maintenance. Installation position should be kept vertical, but must be installed tilt at a velocity. Junction box out of the hole should be down.

thermal resistance should be in accordance with the provisions, wiring, usually use three wire system. Connect wires should be insulated ( It is best to screen open) Copper wire, the cross-sectional area shall be 10 square millimeter, or resistance of the wire should be according to the provisions of the display instrument.
