SITRANS TSthermowell - Industrial Thermowells

SITRANS TSthermowell are customizable protective tubes for demanding processes. Flexible process connections, materials and lengths per DIN and ASME standards.

The SITRANS TS500’s modular design makes it exceptionally versatile, delivering precise temperature measurements even in harsh industrial environments.

This compact temperature sensor delivers highly reliable measurements and seamless integration for industrial automation, even in tight spaces.

SITRANS TSthermowells combine robust construction with millimeter-precise configurability to fit virtually any process setup. Separate delivery of thermowell and sensor enables parallel engineering workflows, speeding up projects and simplifying maintenance. Built from high-quality materials with comprehensive quality controls, they comply with DIN 43772 and ASME B40.9—providing one reliable solution that adapts across industries and global standards.

Separate delivery of thermowell and sensor allows mechanical and instrumentation work to run in parallel, shortening project timelines and enabling sensor replacement without process shutdown.

High-quality materials and comprehensive Siemens quality controls—including material verification, pressure, and leak testing options—deliver long-term stability even under the most stringent process demands.

Choose from global standards (DIN 43772, ASME B40.9), multiple connection types, and different tube forms to match the specific stress, media, and installation requirements of your application.

Flanges acc. to EN 1092-1 and ASME B16.5 Threads (G/R/M/NPT) Standardized weld-in connections Van-Stone connections

½ inch NPT, M18x1.5, M20x1.5; G½ inch and others

316L, carbon steel, Hastelloy, Monel and diverse other coatings possible

Screwed, weld-in, flanged and Van Stone connection types ensure compatibility with existing piping systems and maintenance strategies across plant installations.

Standard lengths up to 1,000 mm with custom dimensions settable to the exact millimeter—available in straight, reduced and tapered tube forms for optimal fit and response.

Beyond standard stainless steel 316L, materials such as Hastelloy® and Monel® as well as Tantalum or PTFE coatings are available for aggressive media and harsh conditions.

Siemens thermowell stress calculation tool validates whether a selected thermowell fits the application. It suggest optimized alternatives if needed, ensuring maximum safety, reliability, transparency, and confidence.

Siemens Product Configurator simplifies selecting matched temperature sensors and thermowells. It validates configurations automatically, letting you order both products together under a unique system ID (optional Y92).

The choice depends on your regional requirements and existing plant specifications. DIN 43772 is widely used in European installations, while ASME B40.9 is the standard for North American plants. Both offer the same range of process connections and tube forms so you can match the standard to your facility without compromising configuration options.

The installation length (U-length) determines how far the thermowell extends into the process. Standard lengths are available, and customer-specific lengths can be configured to the exact millimeter to ensure the sensor tip is optimally positioned for accurate measurement in your specific pipe or vessel.

SITRANS TSthermowell can be ordered with a range of optional inspections per EN 10204-3.1, including material certificates, Positive Material Identification (PMI), pressure tests, helium leak tests, dye-penetration tests, X-ray and ultrasound testing of welds and bore concentricity, as well as NACE conformity and CRN marking.

The Siemens Product Configurator allows customers to easily select the bestfitting temperature sensor and thermowell. The online tool automatically checks in the background whether the selected configuration is a perfect match. Both products can be ordered together, bundled under a unique system ID (optional order code Y92).

Siemens thermowell stress calculation online tool validates whether the selected thermowell, in its specific configuration, is perfectly suited to the customer’s application. When necessary, it proactively recommends optimized alternatives or corrective adjustments. Expect full transparency throughout the design process to reduce risk, prevent costly errors.
