Assembly instructions

Signed sensors ex.jpg II 1/2G IIC T6 ÷ T5 Ga/Gb  et ex.jpg II 1/2D Ex ta/tb IIIC TX Da/Db  have been designed for temperature measurement in all gas, liquid, mist and dust explosion zones. In zone 0 or 20 can only be a protection tube. The connection head can only be in zones 1 (21) or 2 (22). The boundary between the zones is the threaded connection.

Description

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

Construction

The sensor consists of an interchangeable measuring insert, an external protective tube (thermowell) with neck and an aluminum connection head where the mounting of a temperature transmitter with an output signal 4 -20 mA / 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, flange size, thermowell design, connection head as well as type and number of sensors and accuracy 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.
