Overview: What Is the YTA610 Temperature Transmitter?
The YTA610 is a highly accurate, field-mounted temperature transmitter from Yokogawa, designed to convert various temperature sensor
inputs (such as thermocouples, RTDs, resistance, or millivolts)
into standardized output signals suitable for control systems. It
supports both 4–20 mA DC analog output and digital communications via HART® 7 or FOUNDATION™ Fieldbus ITK 6
Key Features & Capabilities
1. Sensor Versatility
Accepts a wide variety of inputs—thermocouples, 2-/3-/4-wire RTDs,
ohms, or DC millivolts. It can be configured with single or dual
sensor inputs, enabling functions like differential or average
temperature measurement and automatic sensor backup in case of
failure
2. Communication Flexibility
Outputs a traditional 4–20 mA analog signal, with digital
communication overlays via HART 7 (superimposed) or through FOUNDATION Fieldbus for fully digital integration
3. High Accuracy & Long-Term Stability
- Offers Pt100 accuracy of ±0.14 °C (±0.25 °F)
- Provides excellent stability: RTDs stay within ±0.1% or ±0.1 °C per
2 years; TCs ±0.1% or ±0.1 °C per year
4. Rugged, Dual-Compartment Design
Built with a dual-compartment field-mount housing that separates electronic circuitry from field wiring—enhancing
durability in harsh industrial environments.
5. Self-Diagnostics & Local Configuration
Includes continuous self-diagnostics, such as sensor failure and
terminal block detection. The Local Parameter Setting (LPS) function (with indicator model) allows easy on-site configuration
via push-buttons—no handheld device required
6. Safety & Global Certifications
- SIL-certified: HART models meet SIL 2 requirements for functional safety
- Holds multiple international approvals: FM, CSA, ATEX, IECEx, INMETRO, KOSHA, EAC, and NEPSI.
7. Lifecycle Support: “Total Insight”
Yokogawa supports the YTA610 through its product lifecycle—from
selection and installation to diagnostics and maintenance—under its
“Sensing → Sensemaking” philosophy, providing tools and support to improve efficiency and
lower lifecycle costs.
