Industrial instrumentation/RTD testing and working Malayalam tutorial
rtd stands for Resistance Temperature Detector,
the resistance changes according to the change of temperature.
Normally in the pt 100 series, the rtd zero degrees is 100ohms.
Each subsequent degree is considered to be .39 ohms.
Thermowell uses an rtd protection device.
Protects rtd at high pressure or high flow areas.
The thermowell connects directly to the measured surface.
So it helps us to reduce the temperature variation to some extent.
The temperature transmitter converts the resistance from rtd into an electrical signal.
Transmitter. Converts the resistance from Rtd to current.
