ABB TK802F

Description

ABB TK802F Product Overview

Basic Information

Key Features

1. Temperature Measurement
   • Type: Typically a thermocouple (e.g., J, K, T, E, R, S, B types, depending on variant).
   • Range: Wide measurement range (e.g., -200°C to +1370°C, specific to thermocouple type).
   • Accuracy: High precision (±1.5°C or ±0.5% of reading, depending on model and calibration).
2. Construction and Design
   • Probe Material: Stainless steel (SS316/304) for corrosion resistance in harsh environments.
   • Sheath Diameter: Common sizes: 3 mm, 4 mm, 6 mm, or 8 mm (customizable for specific applications).
   • Length: Standard lengths (e.g., 100 mm to 1000 mm), extendable for deep penetration into pipelines or machinery.
   • Connection:
     • Termination: Plug-and-play connectors (e.g., M12, Mini-Change) or bare wires for direct wiring.
     • Protection: IP67/IP68-rated connectors for dust and water ingress protection.
3. Environmental Resistance
   • Temperature Rating:
     • Probe: Withstands up to +1400°C (for high-temperature types like R/S/B).
     • Electronics (if integrated): -40°C to +85°C for harsh industrial environments.
   • Vibration/Shock: Compliant with IEC 60068-2 standards (e.g., 20 g shock, 10–2000 Hz vibration).
   • EMC Immunity: Meets IEC 61000-6-2 (industrial EMC requirements).
4. Installation and Compatibility
   • Mounting:
     • Threaded fittings (e.g., M12 x 1, 1/2″ NPT) for flush or screwed-in installation.
     • Flange mounting options for high-pressure applications (e.g., boilers, reactors).
   • Compatibility:
     • Directly interfaces with ABB’s PLCs, DCS systems (e.g., AC800M), or third-party temperature controllers.
     • Output: Analog signal (mV) or digital (e.g., 4–20 mA with optional transmitters).

Typical Applications

• Industrial Processes:
  • Monitoring temperatures in furnaces, ovens, or chemical reactors.
  • Example: In a steel mill, the TK802F (type B thermocouple) measures molten metal temperatures up to 1800°C.
• HVAC and Building Automation:
  • Air handling units, chillers, or boiler systems.
  • Example: In a commercial building, the sensor monitors chilled water temperature in a HVAC loop.
• Energy and Utilities:
  • Steam pipelines, power plant turbines, or renewable energy systems (e.g., geothermal plants).
  • Example: In a biomass plant, the TK802F (type K) measures exhaust gas temperatures in a combustion chamber.
• Machinery and Equipment:
  • Motors, pumps, or compressors for overheating protection.
  • Example: In a paper mill, the sensor detects bearing temperatures in a rotating machine to prevent failures.
