Product description
A cable (pos. 1) goes through an M12 x 1.5 pg connec-
tion. See fig. 65.
The sensor housing and parts in contact with the
medium are made of Inox DIN W.-Nr. 1.4305 (pos. 3)
with composite PA top (pos. 2). The pressure connec-
tions (pos. 4) are DIN W.-Nr. 1.4305, 7/16" UNF, and
gaskets are FKM.
