CHAPTER 3
DESCRIPTION
DIGITAL PT8 is an electronic pressure switch with integrated digital pressure gauge that includes instantaneous reading of the
absorbed current.
The device allows control of the start and stopping of a single-phase pump up to 2.2 kW (3 HP). The pressure is easily adjustable via
the control panel. The wiring is similar to a traditional electromechanical pressure switch. DIGITAL PT8 can operate as a differential
pressure or reverse pressure switch and controls and manages overcurrent, dry running and rapid operation cycles.
