2-46 Model
The air temperature probe is designed to measure temperature environment inside of facilities and outdoors. It's mounting on the flat surface using screws. Exd or Exia design. It applies to measure temperature of explosive environments. The 4-20 mA or 4-20 mA (HART protocol) transducer can be built in the industrial head.
