EXAMPLE of link with marking plate specific information, and wording
Example for a standard temperature MIVI sensor Ex db IIC T3 Gb
Sensor part = vibrating rod (ambient temperature must remain within the range “0 °C < T amb. > 190 °C”
Main body = body of the MIVI sensor (ambient temperature must within the range “0 °C < T amb. > 190 °C”
Enclosure = MIVI sensor from vibrating rod to entry of the cable gland
Pipe = flexible tube or rigid tube
Entry of enclosure = entry of cable gland (ambient temperature must remain below “CABLE ENTR MAX TEMP.: 100 °C”
