Type J thermocouple 131

RTDtype K thermocouplehigh-temperature

Overview
The 131 series comprises MI (mineral-insulated) or assembled thermocouple and RTD sensors designed for precision temperature measurement in demanding industrial environments. Construction uses precision welding and high-temperature alloys; manufacturing relies on micro-machining to ensure conductor uniformity and long service life. Measurement principle: thermoelectric junction potential for thermocouples and resistance variation for RTDs.

Key technical and design points

• Precision welding processes to enhance measurement stability and repeatability.
• High-temperature alloy conductors for operation in extreme temperatures.
• Micro-machining production to maintain conductor geometry and integrity.
• Available sensor types: thermocouples (K, J) and common RTD variants to match temperature range, corrosion resistance and mechanical requirements.

Applications

• Industrial process temperature monitoring in high-temperature/high-pressure environments.
• Laboratory and research settings requiring high sensitivity and stability.
• Medical devices where precise temperature measurement is required.
• Food processing and storage monitoring with hygiene considerations.
• Automotive, energy and power generation, petrochemical, military, thermoelectric, chemical and nuclear industry applications.
