Instructions of montage
Sensors signed II 1/2G IIC T6÷T5 Ga/Gb (FTZU09ATEX0075X) and II 1/2D Ex ta/tb IIIC TX Da/Db (FTZU09ATEX0121X) has been designed for temperature measurement in all explosion zones of gases, liquids, mists and dusts. In zone 0 or 20 can be only protection tube. Connection head can be only in zones 1 (21) or 2 (22). Limit between zones is threaded fitting.
Sensors signed II 2G IIC Tx Gb (FTZU09ATEX0121X) and II 2D Ex tb IIIC TX (FTZU09ATEX0121X) has been designed for temperature measurement in zone 1 (21) and 2 (22).
Description
Resistance thermometers of this series are designed for screw-fitting directly into the process, mainly in vessels and pipelines. These thermometers are suitable for liquid and gaseous media under moderate mechanical load and normal chemical conditions.
Construction
The sensor consists of an exchangeable measuring insert, outer protective tube (thermowell) with neck and aluminum connection head where mounting a temperature transmitter with 4-20 mA/HART® or Profibus®PA output signal is possible.
The measuring insert represents the replaceable element of the complete sensor which reduces time and costs of maintenance of the measuring apparatus installed in the object. Spring fixation of the measuring insert provides perfect pressure to the bottom of the protecting tube, reduces time of reaction to changes of temperature and increases accuracy of measurement as well as reduces natural vibration thus mechanical and electrical defects can be avoided.
Insertion length, process connection, design of thermowell, connection head as well as type and number of sensors, accuracy and method of connection can be selected individually for the respective application.
Temperature transmitter ( Option )
Transmitter is mounted inside the connection head of the sensor, directly on measuring insert.
