Dave’s Corner: Proximity Sensor

Proximity Sensors can be provided on almost any Yamada pump. They are used to send a signal every time the pump completes a cycle. This signal can then be used to count cycles for preventative maintenance. It can also be used to monitor flow rate.

When used for one of these purposes the signal is usually sent to a basic digital counter that has no control capability. In addition to giving a totalized readout in cycles it will also be able to totalize in any engineered unit, such as gallons, cubic feet, cubic meters, liters, etc.

Most basic counters will also be able to give a readout in GPM, L/M, or other flow rates. When using a proximity sensor with a PLC and a solenoid in the air line you can also perform batch metering. In other words, you can pump to a predetermined amount and have the pump shut off at that predetermined amount.

The proximity sensor comes in two configurations. Please consult Yamada America for more information about proximity sensors and their use.

Helpful Hints: Not Your Father’s Dry Run Protector

We receive many calls from end user’s telling us that their pump has failed from dry running . Upon further investigation we find out that their problem is with a competitor’s piston pump, not an air operated double diaphragm pump.

For these applications we have suggested using our DRD-100 Dry Run Detector and have been receiving great results. So remember, dry run can be controlled on our pumps or the competition.
