Temperature Transmitters: YTA110 YTA310/YTA320

TÜV certified SIL 2 for single use in standard configuration and
robust dual-compartment housing to harsh environment

 

Product Information: YTA Temperature Transmitters

YTA Series temperature transmitters convert the sensor signals to a unified signal, 4 to 20mA signal or FOUNDATION™ fieldbus. This eliminates the drawbacks of wire resistance and signal noise that are often experienced with conventional temperature instruments, which must be connected by long extension lead wires or three-conductor cables to converters in an instrument panel room.An additional feature is that both the sensor type and the measurement range can be selected.

List of questions and answers

Q&A for the basic specifications Q What is the YTA110? A The YTA110 is a general-purpose temperature transmitter that achieves high reliability through its dual-compartment housing. An integral indicator allows for checking the measured temperature on site. Q What is the measurement principle of the YTA110? A When a thermocouple is used, the YTA110 measures the electromotive force and terminal block temperature, and uses the electromotive force data to calculate the temperature. When an RTD is used, the YTA110 passes a very small electric current through the RTD to measure electrical resistance. Based on the relationship between resistance and temperature, it then calculates the temperature. Q What are the advantages of the YTA110? A The YTA110 achieves high reliability through its dual-compartment housing and is SIL2 compliant. Q What do I need to consider when I order the YTA110? A The YTA110 is recommended for general applications. You will need to determine what kind of electrical connection is required, whether an integral indicator is necessary, and decide on a mounting bracket type. Q Are there any reference materials for the YTA110? A Catalogs, general specifications, and drawings can be downloaded from our website. ・YTA Series Temperature Transmitter Catalog (908KB) ・List of general specifications (GS) ・List of drawings (SD) Q&A for the product Q How should the burnout direction be set for the YTA110? Which is the default, upscale or downscale? A The burnout is set to upscale as a factory default. When you select the /C1 option, burnout is set to downscale. The burnout settings for CPU and sensor failures are the same.   Q&A: YTA Series | YTA310/320 | YTA50 | YTA70  Temperature Transmitters   September 29, 2008 Released
