List of questions and answers

Q&A for the basic specifications

Q    What are the YTA310/320?

A    The YTA310/320 are temperature transmitters used for high accuracy measurement applications. They are calibrated at the factory for highly accurate input and output.

Q    What is the measurement principle of the YTA310/320?

A    When a thermocouple is used, the YTA310/320 measure the electromotive force and terminal block temperature, and use the electromotive force data to calculate the temperature.

When an RTD is used, the YTA310/320 pass a very small electric current through the RTD to measure electrical resistance.

Based on the relationship between resistance and temperature, they then calculates the temperature.

Q    What are the advantages of the YTA310/320?

A    The YTA310/320 are highly accurate, highly reliable, and SIL2 compliant.

Q    When should I order the YTA310? How about the YTA320?

A    For a FOUNDATION™ fieldbus application, select the YTA320. When BRAIN or HART communication is required, select the YTA310 for single input and the YTA320 for dual input.

Q&A for the product

Q    What is the sensor matching function (Pt100) for the YTA310/320?

A    This function improves temperature conversion accuracy by setting a Pt100 specific constant in the transmitter.

Q    Can one of the YTA320’s dual inputs be used for backup purposes?

A    Yes. The YTA320 supports a sensor backup function that switches output from the first sensor signal to the second sensor signal.
