Mechanical pressure switch DBL series

differentialSPDTfor liquids

The DBL differential pressure switch detects the difference between two pressures applied in two environments with different pressures. Thanks to their constructive simplicity, based on mechanics, differential pressure switches are instruments that do not need to be electrically powered and that are mainly installed on systems or equipment, to prevent failures or malfunctions that are dangerous for the system. To be used in civil, commercial or industrial environments on air conditioning and ventilation systems for: control of clogging of filters; check the correct functioning of the filters; control of depression and overpressure; power failure of batteries in the absence of air.
