# Product Details: Foxboro 130F-N4 Smart Temperature Transmitter ## 1. Product Overview The Foxboro 130F-N4 is an industrial-grade smart temperature transmitter under Schneider Electric’s Foxboro brand, engineered for reliable, high-precision temperature measurement and signal conditioning in critical process control systems. As a key model in the Foxboro 130F series—recognized for ruggedness and long-term stability—it is specifically designed to interface with both thermocouples (TC) and resistance temperature detectors (RTD), converting weak, nonlinear temperature signals into standardized 4-20 mA analog outputs or digital signals via HART protocol.

2. Key Technical Specifications

3. Core Features

• Dual-Sensor Compatibility: Supports 8+ TC types and 6+ RTD types, allowing flexible adaptation to diverse temperature ranges (e.g., -200°C for freezer storage via Pt100, +1600°C for high-temperature furnaces via S-type TC) without replacing the transmitter—reducing inventory costs.
• Reliable Precision Measurement: Delivers consistent accuracy across wide operating conditions, with auto-calibrated CJC eliminating TC measurement errors caused by ambient temperature changes. This is critical for processes requiring tight temperature control (e.g., pharmaceutical batch manufacturing, food pasteurization).
• Harsh-Environment Durability: IP66/IP67 housing protects against dust, heavy rain, and high-pressure water jets, making it suitable for outdoor or wet installations (e.g., offshore oil platforms, wastewater treatment plants). The wide operating temperature range and vibration resistance ensure performance in extreme climates.
• Smart Digital Connectivity: HART 7.0 compatibility enables remote configuration (e.g., adjusting span, units, alarm thresholds) and real-time diagnostics—eliminating the need for on-site visits to hazardous or hard-to-reach locations. The 4-20 mA analog signal ensures backward compatibility with legacy control systems.
• Simplified Installation & Maintenance: 2-wire loop-powered design reduces wiring complexity, while built-in diagnostics (e.g., sensor open circuit alerts) enable predictive maintenance. The compact form factor fits standard junction boxes, minimizing installation space requirements.

4. Application Scenarios

• Oil & Gas: Measures temperature in crude oil pipelines (K-type TC: -200°C to +1260°C), wellhead equipment (Pt100: -200°C to +850°C), and refinery distillation columns. Resists corrosion from hydrocarbons and withstands high vibration, ensuring safe fluid transport.
• Chemical Processing: Monitors temperature in reactor vessels (B-type TC: +600°C to +1820°C for high-temperature reactions) and solvent storage tanks (Pt100: -40°C to +200°C). Complies with ISO 9001 quality standards and supports process optimization.
• Power Generation: Tracks temperature in steam turbine bearings (Pt100: -50°C to +200°C) and boiler tubes (K-type TC: +600°C to +1200°C). High accuracy prevents equipment overheating and ensures grid stability.
• Pharmaceuticals: Controls temperature in lyophilizers (freeze dryers: Pt100, -50°C to +50°C) and cleanroom ovens (E-type TC: -200°C to +900°C). Complies with FDA 21 CFR Part 11 via HART data logging (audit trails) for regulatory compliance.
• Food & Beverage: Maintains temperature in pasteurization lines (T-type TC: -200°C to +350°C, ±0.5°C accuracy) and refrigerated warehouses (Pt100: -40°C to +20°C). IP67 rating withstands washdown procedures, meeting USDA food safety requirements.

5. Installation & Configuration Notes

• Mounting Guidelines:
  • Field-mount on sensor junction boxes or pipe-mount via optional bracket (part number 130F-BRK-PIPE).
  • Orient the housing downward to prevent water pooling (maintains IP67 compliance).
  • Keep ≥100 mm clearance from high-voltage cables (>1 kV) to avoid electromagnetic interference (EMI) with sensor signals.
• Wiring Instructions:
  • Use shielded twisted-pair cables (22 AWG minimum) for sensor inputs (TC/RTD) to reduce noise. Ground the shield at the controller end only.
  • For 4-20 mA loop wiring, ensure correct polarity (positive terminal to DCS/PLC output, negative to ground) to avoid transmitter damage.
  • RTD 4-wire configuration is recommended for distances >50 m to eliminate lead resistance errors.
• Configuration Steps:
  1. Connect a HART communicator to the transmitter’s loop terminals (no power shutdown required).
  2. Select the sensor type (TC/RTD) and input range (e.g., “Pt100, -50°C to +200°C”) via the communicator menu.
  3. Perform zero calibration using a NIST-traceable temperature reference (e.g., dry-block calibrator set to 0°C).
  4. Enable diagnostic alerts (e.g., “sensor short circuit”) and set the HART polling address (1-15) for DCS integration.
• Maintenance Recommendations:
  • Calibrate annually with a precision temperature calibrator (e.g., Fluke 9175) to maintain accuracy.
  • Inspect wiring connections quarterly for corrosion (especially in coastal/humid environments) and tighten loose terminals.
  • Clean the housing with a damp cloth (avoid harsh chemicals) to keep LED indicators visible.
