Q&A for the basic specifications
Q What is the YTA70?
A The YTA70 is a 2-wire temperature transmitter that can be mounted in a DIN Form B-compliant temperature sensor housing without modification. As no special housing or mounting bracket is needed, it costs less to install.
Settings such as sensor type and temperature range can be easily changed through HART communication.

Q What is the measurement principle of the YTA70?
A When a thermocouple is used, the YTA70 measures the electromotive force and terminal block temperature, and uses the electromotive force data to calculate the temperature.
When an RTD is used, the YTA70 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 YTA70?
A The YTA70 is more cost efficient and is easy to mount. Settings can be easily changed through HART communication.

Q What do I need to consider when I order the YTA70?
A The YTA70, which makes it easy to change settings through HART communication, is recommended for applications where the sensor type or measurement range may change and where the transmitter is mounted in a DIN Form B-compliant sensor housing.

Q Are there any reference materials for the YTA70?
A Catalogs, general specifications, and drawings can be downloaded from our website.
