SITRANS TSinserts

SITRANS TSinserts Inserts are exchangeable measuring inserts with wide sensor selection, configurable dimensions and hazardous-area certifications.

SITRANS TSinserts are exchangeable measuring inserts with wide sensor selection, configurable dimensions and hazardous-area certifications.

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

Configurable protective tubes for demanding processes—protecting sensors in harsh industrial environments while ensuring accurate, safe temperature measurement.

Head-mounted temperature transmitters for reliable measurement, easy integration, and advanced diagnostics, from standard to high-availability applications.

Available as European (DIN) or American (ANSI spring-loaded) types, SITRANS TSinserts 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.

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.

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.

Direct sensor signal 4…20 mA (SITRANS TH100/TH320) HART (SITRANS TH320/TH420) PA (SITRANS TH420)

Pt 100 Basic: –30…+400 °C (-22…752 °F) Pt 100 Extended: –196…+600 °C (-321…1112 °F) Thermocouple –196…+1100 °C (-321…2012 °F) (Depending on type of TC)

IP54-68, depend on type of connection head

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.

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 SITRANS TS500 or compatible thermowell.

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.

Yes—that is their primary purpose. SITRANS TSinserts are designed as exchangeable measuring inserts for the SITRANS TS500 series. You can replace a worn or failed insert without removing the thermowell from the process to significantly reduce maintenance downtime. Simply match the tip diameter, insertion length and sensor type to your existing configuration. Use article number 7MC701 in the Siemens PIA Life Cycle Portal for online configuration and exact specification.

SITRANS TSinserts offer a comprehensive range of explosion protection certifications. For European and IECEx markets, options include intrinsic safety Ex ia (Zone 0/1), non-sparking Ex ec (Zone 2) and compatibility with flameproof enclosures Ex d. For North American markets, FM and CSA approvals are available, including flameproof and non-sparking variants. You can also order the assembly with a SIL 2/3 functional safety certificate for safety-instrumented systems when combined with the SITRANS TH320 or TH420 transmitter.
