Siemens SITRANS TS500 Tubular Thermowells Temperature Sensor


  • Exchangeable during operation
  • Wide application range due to modular design
  • Explosion protection by the ignition protection types, intrinsically safe Ex i (IS), increased safety Ex e (NI) or flameproof enclosure Ex d (XP) resp dust protection by means of enclosure Ex t (DIP)
  • Certificates for major markets
  • With optional local indicator and operation

Siemens SITRANS TS500 Tubular Thermowells Temperature Sensor is suitable for a broad spectrum of measurement needs, spanning from straightforward to intricate applications, including challenging environments. The system’s modular construction incorporates components such as a protective tube made from tubular or solid material, an extension, a connection head, an optional transmitter, or a display, allowing for the utilization of standardized elements. Additionally, intrinsically safe or flameproof configurations are accessible as well.
