What is T/C, What is RTD?

What is T/C, What is RTD?

Refer to the temperature sensors selection, many people, who are not skilled at technology, are usually confused for T/C and RTD: what is T/C, what is RTD?

Here, let's us explain them in brief to the unfamiliar persons to get faster knowledge.

T/C and RTD are different two types of sensors. 

T/C=Thermocouple. 

RTD = Resistance Temperature Detector. 

For Yokogawa temeprature transmitters, you can select sensor inputs: thermocouples (T/C), RTDs, ohms, or DC milivolts, depending on your application.

However, T/C (Thermocouple), the temperature range you can measure is much wider, but lower accuracy. While RTD (Resistance Temperature Detector), narrower temperature range, but higher accuracy.

In Yokogawa temperature transmitters:

For T/C (Thermocouple), sensor types J, K and T are more used often.

For RTD (Resistance Temperature Detector), PT100 is frequently used. 

T/C is two-wire, while PT100 is three-wire.

What's important, T/C input signal and RTD input signal can not be achieved for a same Yokogawa temperature transmitter, at the same time.

Anyway, no matter how much your Yokogawa temperature transmitter's temperature range, sensor type setting, you can use Yokogawa BT200, or Rosemount Field Communicator 475, or YHC4150, YHC5150 to adjust freely, according to your needing.
