The 2700 dual point switch is the two-set-point version of SOR's newest ultrasonic level switch, launched in 2025. It replaces the need to choose between SOR's earlier 712 and 722 models: failsafe, time delay and self-test are now standard on every unit. For a single alarm point, see the 2700 single point.
The two set points can work as independent high and low alarms, or be linked to start and stop a pump, with the pump logic included at no extra cost. Each set point uses a pair of crystals across a sensor gap: when liquid fills the gap the ultrasonic signal gets through and the relay changes state. With no moving parts there is no calibration, and maintenance is an annual visual inspection.
