Premium Field Temperature Transmitter for Critical Applications
The Yokogawa YTA710 is an advanced field-mount temperature transmitter designed for applications where measurement accuracy, reliability, and diagnostic capability are essential.
As the premium model in the YTA temperature transmitter family, the YTA710 combines Yokogawa’s temperature measurement expertise with advanced sensor processing, communication capability, and device health information to support modern process automation requirements.
Exceptional Temperature Measurement Accuracy
The YTA710 provides one of the highest accuracy levels in Yokogawa’s temperature transmitter portfolio.
For Pt100 input, the transmitter achieves accuracy up to:
This high accuracy makes the YTA710 suitable for applications where small temperature deviations can affect product quality, process efficiency, or safety.
Universal Sensor Input for Flexible Engineering
The YTA710 supports a wide range of temperature sensor inputs:
- RTD
- Thermocouple
- Resistance (Ohm)
- DC millivolt input
This universal input capability allows engineers to select the most suitable sensor technology without changing the transmitter platform.
Dual Sensor Input with Backup Function
The YTA710 supports single or dual sensor configurations.
With dual sensor input, the transmitter can perform:
- Differential temperature calculation
- Average temperature calculation
- Sensor backup switching
If the primary sensor fails, the transmitter can automatically switch to the backup sensor, improving process availability and reducing unexpected shutdown risks.
Sensor Matching Technology for Higher RTD Accuracy
For high-accuracy temperature applications, the YTA710 supports optional sensor matching technology.
Although RTD sensors follow standardized resistance-temperature curves, individual sensors may have small differences caused by manufacturing variations.
By using sensor-specific Callendar-Van Dusen coefficients, the YTA710 can compensate for these differences and improve measurement accuracy beyond standard RTD calibration.
Advanced Diagnostics for Predictive Maintenance
Compared with standard temperature transmitters, the YTA710 provides enhanced diagnostic functions to help maintenance teams understand device and sensor conditions.
Additional diagnostics include:
- Thermocouple short detection
- RTD short detection
- RTD corrosion detection
- Temperature cycle monitoring
These functions help identify potential sensor problems before they affect production.
Designed for Harsh Industrial Environments
The YTA710 uses a rugged dual-compartment field housing design.
The separated terminal and electronics compartments help protect internal electronics from field wiring conditions and simplify installation and maintenance.
Available housing options include:
- Low copper aluminum housing
- Stainless steel housing
The transmitter supports demanding outdoor and industrial environments with IP66/IP67 protection.
Multiple Communication Options
The YTA710 supports different communication protocols depending on configuration:
- HART 7
- FOUNDATION Fieldbus ITK 6
- BRAIN Protocol
Digital communication enables easier configuration, device diagnostics, and integration into modern plant asset management systems.
SIL Safety Capability for Critical Processes
The YTA710 is designed for safety-related temperature measurement applications.
According to Yokogawa, the transmitter is certified according to IEC 61508 and can be applied in:
- SIL 2 single transmitter applications
- SIL 3 dual transmitter applications
This allows one transmitter platform to serve both standard process measurement and safety applications.
