Water Level Controllers products

The 2SPD16-STK Checkpoint SmartProbe sensor stick is used in dirty water applications. The sensor stick provides a Simplex Pump Down with High Alarm using two switch outputs. The sensor uses a differential between the Pump On and the Pump Off probes to determine when the Pump function is needed. This hysteresis allows for the control over On and Off functions using a single switch output.

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.
