Thermocouple-equipped temperature probes are perfect for measuring temperatures as high as +1,700 °C. They are made up of two distinct metals that are connected to create a thermocouple.
Thermowells that are solidly drilled to meet the demands of the oil and gas sector. The ASME PTC 19.3 2010-TW standard for thermowell stress computation served as the foundation for the TSW400’s design. completely complies with ASME standards and the demands of this most exacting sector.
This product gives you complete assurance that the solution is robust, safe, and dependable.
Reliable Protection for Temperature Sensors in Harsh Process Environments
The TSW400 Thermowell is a rugged and precisely engineered protective fitting designed to shield temperature sensors (such as RTDs and thermocouples) from direct exposure to process media, ensuring accurate measurement and extended sensor life in industrial applications.
