Temperature sensor PT100 thermal resistance RTD with diamter 1.5mm
composition
The outer appearances of the sheath platinum RTD are quite
different according to their different use requirements. But their
basic structures are approximately the same . It is usually
composed of the main components such as sheath platinum RTD
thermosensitive elements, mounted fixed devices, connection boxes
and so on.
Working Principle:
Thermocouple is composed of temperature sensor and signal
converter, signal converter is installed in the junction box of
temperature sensor, temperature sensor produce resistance or
potential effects made by the temperature affect, via
transformation to create a differential voltage signal. The signal
via the amplifier amplification, then through voltage and current
transformation, output 4-20 mA current signal corresponding to the
range.
