  • Single and dual RTD
  • Interchangeable mineral insulated measuring insert
  • Process connection welded to the protective tube
  • Protection tube diameter: Ø9, Ø10, Ø11, Ø12, Ø15 mm
  • Protective tube material: stainless steel 1.4541 (AISI321) or other
  • ATEX cable gland I M1, II GD, IP65 (cable diameter Ø5..10mm)
  • Output signal: RTD or 4..20 mA (option)


Resistance thermometers in this series are designed to be screwed directly into the process, primarily into vessels and pipelines. These thermometers are suitable for liquid and gaseous media under moderate mechanical load and under normal chemical conditions.


The sensor consists of an interchangeable measuring insert, an outer protective tube (thermowell) and an aluminum connection head where the mounting of a temperature transmitter with a 4-20 mA output signal / HART® or Profibus®PA is possible.

The measuring insert is the replaceable part of the complete sensor which reduces the time and cost of maintaining the measuring device installed in the object. The spring-loaded attachment of the measuring insert provides perfect pressure at the bottom of the protection tube, reduces reaction time to temperature changes and increases measurement accuracy and reduces natural vibrations, thus avoiding mechanical and electrical faults .

Insertion length, process connection, thermowell design, connection head as well as type and number of sensors, accuracy and connection method can be individually selected for the respective application.

Temperature transmitter (option)

The transmitter is mounted inside the sensor connection head: directly on the measuring insert or in the top cap of the head.


The second method is advantageous because it allows to quickly change the standard measurement support without having to disassemble the transmitter; this means reduced sensor maintenance time and costs and the protection of wires from possible damage. Mounting of two transmitters inside the connection head available on request.
