Yokogawa YTA 310 pressure transmitter
China [CN] YTA110 Temperature Transmitter
The YTA110 is the high performance field-mount temperature transmitter that accepts a single sensor input. This input can be from a RTD, thermocouple, ohm, or DC millivolt. It converts the sensor input to a 4 to 20mA DC analog signal. The YTA110 supports either BRAIN or HART® 5 digital communication protocol. The YTA110 is the choice for control and safety applications.
Features:
Outstanding performanceMicroprocessor-based sensing technology ensures high accuracy and stability. High reliabilityDual-compartment housing realizes high resistance capability to harsh environments. SIL CertificationYTA series temperature transmitters have been certified by TÜV NORD as being compliant with the requirements of the IEC61508 for SIL 2. Variety of sensor inputsThe type of sensor input is user-selectable: thermocouples, RTDs, ohms, or DC milivolt. Digital communicationThe 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 functionContinuous self-diagnostics capability ensures long-term performance and lower cost of ownership. LCD display with bargraphThe 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.
