Yokogawa YTA110 YTA 310 YTA320 Temperature Transmitter 4 to 20mA DC with digital communication HART protocol G1/2 1/2NPT M20 

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 TÜV 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.
