- The 3SPD24-STK Checkpoint SmartProbe sensor stick is used in dirty water applications. The sensor stick provides a Duplex Pump Down function with High Alarm using three switch outputs.
- Programming logic provides a sequence on and all off function for Pumps 1 and 2. Each pump will turn on when water contacts its respective sensor ring and both pumps will turn off when water is below the All Pumps Off sensor ring.
- The sensor uses a differential between the Pump 1 On and All Pumps Off to determine when the Pump 1 is needed and a similar differential between Pump 2 On and All Pumps Off. This hysteresis allows for the control over On and Off functions using a single switch output for each pump.
