Atex Explosion Protected Triple Zener Barrier Zener3
The Triple Zener Barrier Zener3 is a “three barriers in one” solution for the connection between a weighing terminal and a weight receiver system in the ATEX ZONE. This “3 in 1” feature protecting the excitation line, signal and sense which makes installation much easier.
