Extension lead wire thermocouple and resistance temperature detector_R300 series_R311, R312, R321, R322, R331, R332
Type: R300
 
Service intended
This type of detector does not use terminal head, rather it directly connects to an indicator or a transmitter. It is very useful where the distance between measuring parts and the location of its head is too far. The measuring parts and its head can be connected by using an extension wire. Extension wire can be selected according to its installation site condition, its protection shape of armored tube, and its wire covering material.
