Detailed Product Description

Features: Temperature Transmitters YTA110 YTA310/ YTA320
Outstanding performance
Microprocessor-based sensing technology ensures high accuracy and stability.

High reliability
Dual-compartment housing realizes high resistance capability to harsh environments.

SIL Certification
YTA series temperature transmitters have been certified by TÜ V NORD as being compliant with the requirements of the IEC61508 for SIL 2.

Variety of sensor inputs
The type of sensor input is user-selectable: thermocouples, RTDs, ohms, or DC milivolt.

Digital communication
The BRAIN and HART communication protocols are available.
The instrument configuration can be changed by the user with a BT200 terminal or HART communicator.
The YTA320 temperature transmitter also supports FOUNDATION fieldbus communication protocol.

Self-diagnostics function
Continuous self-diagnostics capability ensures long-term performance and lower cost of ownership.

LCD display with bargraph
The LCD display simultaneously displays a digital readout and a bargraph.

Dual universal inputs ( Model YTA320)
The YTA320 can accept two thermocouple, RTD, ohm, or DC milivolt inputs. Differential or average temperature transmitter measurement can be selected. A sensor backup function automatically switches-over from the primary sensor to a backup if the sensor fails.
