Yokogawa YTA610 Temperature Transmitter
Product Description
Yokogawa YTA610 Temperature Transmitter
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.
