Yokogawa YTA610 Temperature Transmitter Field Mount  

The YTA610 is the highly accurate temperature transmitter that accepts Thermocouple, RTD, ohms or DC millivolts inputs and converts it to a 4 to 20 mA DC or Fieldbus signal for transmission.
The YTA610 supports HART® and FOUNDATION fieldbusTM communication protocols.HART types are certified as complying with SIL 2 for safety requirement.

The YTA610 provides high accuracy, stability, and reliability. The housing structure adopts reliable dual-compartment structure. The sensor input can be choice of single or dual inputs. This input can accept the RTD, thermocouple, ohm, or DC millivolt. It converts the sensor input to a 4 to 20 mA DC analog signal or Fieldbus digital signal. HART® 7 Protocol or FOUNDATION™ Fieldbus ITK 6 version are available. The dual input can accept two sensors calculation of the differential or average value and the sensor backup function. Sensor backup functions for automatically switches-over from the primary to the backup upon sensor failure.
By adoption of local parameter switch on the Indicator, it becomes easy to do the on-site setting work.
 

YTA610 features include:

• Dual-compartment field-mount housing
• Choice of HART® 7, or FOUNDATION™ Fieldbus ITK 6 Protocol
• Local Parameter Setting function (Indicator model)
• Basic diagnosis
