YTA310 Field Mount Temperature Transmitter

Brand: Yokogawa Electric Corporation

The YTA310 is the highly accurate temperature transmitters that accept Thermocouple, RTD, ohms or DC milivolts inputs and converts it to a 4-20 mA DC signal for transmission. 

The YTA310 is a single sensor input model. The models support either BRAIN or HART communication protocol, also supports FOUNDATION fieldbus. 

The YTA310 in their standard configuration, with the exception of the Fieldbus type, are certified by TÜV as complying with SIL 2 for safety requirement.
