1 General Specifications YTA70 Temperature Transmitter The YTA70 is the highly accurate temperature transmitter that accepts Thermocouple, RTD, ohms or DC millivolts inputs and converts it to a to 0 ma DC or Fieldbus signal for transmission. The YTA70 supports HART and FOUNDATION fieldbus TM communication protocols. FEATURES High reliability Dual-compartment housing realizes high resistance capability to harsh environments. Variety of sensor inputs The type of sensor input is user-selectable from thermocouples (T/C), RTDs, ohms, or DC millivolts. Digital communication HART protocol revision is 7 and FOUNDATION fieldbus TM ITK vesion is 6.. The instrument configuration can be changed by the user with using the Fieldmate or Handheld terminal. Local Parameter Setting Parameter configuration by the push button offers easy and quick setup for parameters. Self-diagnostics function Continuous self-diagnostics capability ensures longterm performance and lower cost of ownership. Dual universal inputs Dual input can accept two thermocouple, RTD, ohm or DC millivolt 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.
