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.
Signed sensors ex.jpg II 2G IIC Tx Gb et ex.jpg II 2D Ex tb IIIC TX Db have been designed for temperature measurement in zones 1 (21) and 2 (22).
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 .
The length and design of the thermowell, the connection head as well as the type and number of sensors and the 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.
