ZC Low voltage circuit, IP65 waterproof differential pressure switch, various center threads
Use in areas where IP65 waterproofing is required. Medium positive, negative or differential pressure detection. Water level measurement, detection of clogging of water filters.Minimum water pressure detection on water heaters and boilers. This pressure switch is much more sensitive than snap-action systems and can be calibrated at lower pressures, but its use is limited to low power applications, typically on electronic circuits. Very low differential, less than 1 kPa (10 millibars, 0.15 PSI)
