Hydropa Pressure Switch, Full Series DS117, DS507, DS307
Product Overview
Hydropa pressure switch is original German piston-type pressure monitoring component, including full series DS117, DS507 and DS307. It serves as critical safety protection part for hydraulic system on industrial and construction Machine. This pressure switch adopts piston-spring structure with adjustable switching pressure range, maximum pressure resistance up to 500 bar. It delivers stable performance under continuous working conditions and excellent anti-shock capability, monitoring pressure changes inside the hydraulic system and sending electrical signal once pressure reaches preset threshold to protect the whole Machine from overload damage.
Different models cover various pressure ranges: DS307 for low to medium pressure, DS117 for medium pressure, DS507 for high pressure applications. All are genuine Hydropa products, widely used for pressure monitoring and safety cut-off in diverse hydraulic system.

Working Principle
When the Machine is running, hydraulic oil pressure from the hydraulic system acts on the internal piston of the pressure switch. The piston pushes against the preloaded spring. Once hydraulic pressure reaches the preset value, the piston triggers the built-in microswitch and outputs an electrical signal. Users can adjust the set switching pressure by tuning the top adjustment screw. When system pressure drops below the setting value, the microswitch resets automatically. This signal can control pump unloading, alarm or equipment stop to safeguard the hydraulic system and the whole Machine.
