Product Overview

The WRNK mineral insulated thermocouple sensor is designed for fast and reliable temperature measurement in high-temperature and demanding industrial environments. With thermocouple wires insulated by compacted magnesium oxide (MgO) and protected by a durable metal sheath, it provides excellent mechanical strength, vibration resistance, and rapid thermal response. The flexible mineral insulated structure allows easy installation in complex equipment configurations, while various thermocouple types and customizable probe dimensions provide solutions for different process requirements. WRNK is ideal for high-temperature applications such as industrial furnaces, heat treatment systems, chemical processing, power generation, and industrial process control.

Key Features

  • Supports a wide temperature range from -200°C to +1850°C, suitable for high-temperature industrial measurement applications.
  • Designed for high-temperature applications including furnaces, boilers, heat treatment equipment, and industrial heating systems.
  • The small sheath diameter and low thermal mass enable rapid response to temperature changes, making WRNK suitable for dynamic heating processes.
  • The mineral insulated construction allows flexible bending installation, making it suitable for complex installation environments.
  • The thermocouple wires are insulated with chemically stable magnesium oxide (MgO), providing excellent insulation performance and extended service life.
  • The compact mineral insulated structure provides strong vibration resistance and reliable operation in harsh industrial environments.
