Product description

The Yokogawa YTA110 is a rugged, field-mount  temperature transmitter  designed to convert sensor signals (thermocouples, RTDs, ohms, or DC mV) into a standard 2-wire 4–20 mA DC output for  reliable process transmission. Engineered for harsh industrial environments, it delivers long-term stability, flexible  communication, and compliance with key safety standards—ideal for temperature measurement in oil & gas, chemical,  power, and general industrial applications.

Core Features

1. Universal Input Flexibility

   Supports thermocouples (E, J, K, N, T, R, S, B, WRe/W5), 2/3/4-wire RTDs (Pt100, JPt100, etc.), ohms, and DC mV      signals. User-selectable input types eliminate the need for multiple transmitters, simplifying inventory and      setup；

2. High Precision & Long-Term Stability

   Delivers ±0.1% of calibrated span typical accuracy. For RTDs, stability is ±0.1% of reading or ±0.1°C per 2 years      (at 23±2°C); for thermocouples, ±0.1% of reading or ±0.1°C per year—ensuring consistent performance over extended      use；

3. SIL2 Safety Certified

   TÜV NORD-certified to IEC 61508 for SIL2 compliance (single transmitter) and SIL3 (dual transmitter      configuration). Critical for safety instrumented systems (SIS) in high-risk industries, reducing safety-related      design complexity；

4. Rugged Environmental Resistance

   Features a dual-compartment aluminum alloy housing (stainless steel optional) with IP66/IP67 protection and NEMA      4X rating. Hermetically sealed terminals resist moisture, dust, and chemicals—performing reliably in -40°C to 85°C      environments (with integral indicator: -30°C to 80°C)；

5. Digital Communication & Smart Configuration

   Supports BRAIN or HART® protocols, enabling remote parameter setup, calibration, and diagnostics via tools like      the BT200 or HART communicator. Digital communication reduces on-site visits and maintenance costs；

6. Advanced Diagnostics & Self-Calibration

   Continuous self-diagnostics monitor for input loss, ambient temperature errors, EEPROM/cPU failures, and      more—storing up to 4 error logs. Automatic self-calibration compensates for drift, ensuring long-term accuracy      with minimal interventionweb-material3.yokogawa.com；

7. Flexible Output & Failure Modes

   4–20 mA output with selectable sensor burnout (3.6 mA low/21.6 mA high) and configurable failure modes      (upscale/downscale). Damping time constant (0–99s) optimizes signal stability for noisy processes；
