Temperature Transmitters YTA110,YTA310/YTA320
YTA Series temperature transmitters convert the sensor signals to a
unified signal, 4 to 20mA signal or FOUNDATION? fieldbus.
This eliminates the drawbacks of wire resistance and signal noise
that are often experienced with conventional temperature
instruments, which must be connected by long extension lead wires
or three-conductor cables to converters in an instrument panel
An additional feature is that both the sensor type and the
measurement range can be selected.
Features: Temperature Transmitters YTA110 YTA310/YTA320
Microprocessor-based sensing technology ensures high accuracy and
Dual-compartment housing realizes high resistance capability to
YTA series temperature transmitters have been certified by TV 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.
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.
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
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
