Press-switch VTT

The press-switch type VTT, studied and designed to fit on top of silos or hoppers, sends a signal when a limit pressure is reached. The standard setting is 400 mm H2O column and normally the signal from VTT is used to stop a charghing of material or to send an alarm signal to a control panel (normally before the overpressure valve starts working). The VTT has an aluminium body complete of an O-ring on the upper part which ensures the device to be dust-proof, and has an electromechanical switch sensitive to pressure changes.
