Main applications
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).
