Product Details

Low Cost Japan Yokogawa Single Sensor Input YTA310/320,high Accurate Temperature Transmitters


YTA310 and YTA320 are the highly accurate temperature transmitters 


The YTA310 and YTA320 are the highly accurate temperature transmitters that accept Thermocouple,

RTD, ohms or DC milivolts inputs and converts it to a 4 to 20 mA DC signal for transmission. The YTA310 is a single sensor input model, and the YTA320 is a dual input model. Both models support either BRAIN or HART ® communication protocol, and YTA320 also supports F OUNDATION fieldbus TM .

The YTA310/320 in their standard configuration, with the exception of the Fieldbus type, are certified by T U ¨ V as complying with SIL 2 for safety requirement.


FEATURES

Outstanding performance

Microprocesser-based sensing technology ensures

high accuracy and reliability.

High reliability

Dual-compartment housing realizes high resistance

capability to harsh environments and the YTA310/

320 have SIL2 capability for safety requirement.

Variety of sensor inputs

The type of sensor input is user-selectable from

thermocouples (T/C), RTDs, ohms, or DC milivolts.

Digital communication

BRAIN or HART ® communication protocol is avail-

able. The insturment configuration can be changed

by the user with using the BT200 or HART ® commu-

nicator.
