Limit Switches - Inductive Alarm Switch
One or two electronic limit switches type SJ2-N can be installed in the
indicator housing to allow initiation of signaling or switching functions on a
preset flow value being reached. The SJ2-N limit switch operates as a slot
initiator that is inductively actuated by a cam mounted to the pointer. Any
flow value can be used for setting the limit value by sliding the switch along
the slot in the mounting plate for the initiators. Minimum setting distance
between two limit switches is approximately 50% of the scale range.
