Wide sensor selection up to Class AA
Choose Pt100/Pt1000 RTDs—basic, vibration-resistant or extended-range—or thermocouples (types K, J, N, E, T, R, S and more). Single or dual elements are available, with RTD accuracy up to IEC Class AA.
Why SITRANS TS Inserts?
Available as European (DIN) or American (ANSI spring-loaded) types, SITRANS TS Inserts install directly into SITRANS TS500 assemblies without removing the thermowell. A wide selection of RTD and thermocouple sensors, configurable lengths and tip diameters, and optional TH-series transmitters cover a broad range of process requirements.
Key benefits
Minimize downtime with fast insert exchange
Replace the measuring insert without disturbing the thermowell or process seal. Significantly reduce maintenance time, restore accurate measurement quickly, and keep your assets online with minimal intervention.
Standardize across global sites
European DIN variants offer a ceramic base or flying leads for transmitter mounting. The American ANSI spring-loaded design ensures reliable thermowell contact. Both types fit TS500 connection heads worldwide.
Standardize across global sites
ATEX and IECEx certified for intrinsic safety (Ex ia), flameproof enclosures (Ex d) and non-sparking (Ex ec). FM and CSA approvals are also available. SIL 2/3 functional safety is supported when paired with SITRANS TH320/TH420.

Configurable lengths and tip diameters
Tip diameters of 6, 8, or 10 mm suit different thermowell bores. Lengths range from 45 to 2,000 mm and can be specified to the millimeter for precise fitment in any TS500 or compatible thermowell.

Integrate transmitters your way
Mount TH-series head transmitters on the DIN flying-leads variant for 4–20 mA, HART 7 or PROFIBUS PA output. The SITRANS TH420 adds dual-sensor input with hot backup for high-availability applications.
