CYCLE SENSOR KITS
67386 can be used on the following diaphragm pumps:

GENERAL DESCRIPTION
The ARO diaphragm pump cycle sensor kits provide a closed contact
output each time the pump completes a cycle. This signal may be used
to record cycles for maintenance purposes or batching if the discharge
volume of each complete cycle is known.
Some parts of the pump must be replaced with those included in the kits
to enable the activation of the switch.
OPERATION
Maximum Operating Voltage - 200 V DC.
Switching Current - 0.5 Amps
Once the kit is installed in the pump, it may be interfaced with a control
device in the following ways:
As a SOURCING switch (see figure 1) for use with PLC’s.
As a SINKING switch (see figure 2) for use with PLC’s.
As a closed contact switch (see figure 3) for use with meters.
