Pressure switch Italtecnica PM/5G (220 v, 5 bar) Review

The PM/5G pressure switch is designed for automatic control of any single-phase electric pump with a power of up to 2.2 kW. The pump turns on when the pressure drops in the system (the taps are open), and, accordingly, turns off when the pressure in the system reaches the upper threshold. Relay factory setting: lower limit - 1.4 bar, upper limit - 2.8 bar. The operating settings are made by adjusting the screws on the base of the relay and are extremely simple. The small spring is responsible for the delta (the difference between the settings), the large one is for the lower pressure. The connection nut to the device is a union nut, which facilitates the process of installing the device. The maximum pressure is 5 bar.
