Yokogawa Temperature Transmitter YTA710

The YTA710 features high precision, high stability and high reliability. The shell structure adopts a reliable double-chamber structure. The sensor input can be selected as single input or dual input. It can accept various input signals such as RTD, thermocouple, resistance, and DC voltage. It converts the sensor input into a 4-20 mA DC analog signal or a fieldbus digital signal. HART 7 protocol, BRAIN protocol or FOUNDATION™ Fieldbus ITK 6 version are provided. Dual input can accept the differential or average calculation of two sensors and also realize the sensor backup function. The sensor backup function is used to automatically switch from the main device to the backup device when the sensor malfunctions. The on-site parameters can be set by using the on-site parameters button on the indicator.

Yokogawa Temperature Transmitter YTA610

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.
