Adjustable 100 - 800 bar | Micro-Switch Output | Pressure-Guard Power Pack Compatible
The Yale VPS-1 is an adjustable pressure switch with control range from 100 to 800 bar, providing an electrical micro-switch output (alternating contact) when pressure reaches a set value. Yale designs the VPS for automatic pressure limiting, pressure value reporting, and as an automatic motor on/off switch within pressure-guard power packs.
Electrical switching from hydraulic pressure
Yale documentation lists three primary VPS applications: automatic pressure limiting (cuts power when pressure exceeds set value), reporting of a certain pressure value (to PLC or alarm), and automatic motor on/off switching with pressure-guard power packs. As soon as the pressure has reached the set value, the micro-switch is activated. Should the pressure drop, the micro-switch starts the pump again to rebuild pressure. The repeat accuracy is 10 bar.
Per Yale: automatic pressure limiting, pressure-value reporting to control systems, and automatic motor on/off switching for Yale pressure-guard power packs. The pressure-guard application is particularly useful where load pressure must be maintained over very long periods.
