YOKOGAWA YTA310, YTA320 Temperature Transmitter

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 FOUNDATION fieldbusTM.

The YTA310/320 in their standard configuration, with

the exception of the Fieldbus type, are certified by

TÜV as complying with SIL 2 for safety requirement.

For the specifications of Fieldbus communication type

marked with “◊”, refer to GS 01C50T02-00EN.

 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

available. The insturment configuration can be

changed by the user with using the BT200 or HART®

communicator.

Self-diagnostics function

Continuous self-diagnostics capability ensures

longterm performance and lower cost of ownership.

LCD display with bargraph

The LCD display provides both a digital readout and

percent bargraph simultaneously.

Dual universal inputs (Model YTA320)

The YTA320 can accept two thermocouple, RTD,

ohm or DC milivolt inputs. Differential or average

temperature measurement is selectable. The sensor

backup function for automatically switches-over from

the primary to the backup upon sensor failure.
