High-performance temperature sensors for the most demanding environments

Thermocouples are particularly suited for high-temperature applications found in the chemical, petrochemical, and refinery industries. Their advantages are many, including a fast response time (thanks to a small diameter) and lower cost. And with conductor cables encased inside a mineral-insulated sheath, thermocouples perform reliably in processes with high pressure and vibration. Thermowells provide additional protection against corrosive process media and extreme operating conditions. WIKA offers a comprehensive portfolio of thermocouples with multiple temperature ranges, connection heads, output signals, and safety certifications.

What measures should be taken when installing high-temperature probes with ceramic protection tubes?

To prevent the ceramic tube from thermal stress, the installation should be done slowly and with gradually increasing temperatures. For example, insert it 4 to 8 inches (10 to 20 cm) per minute at 2,192°F (1,200°C) and ~1/2 inch (1–2 cm) per minute ...
