A pressure switch is defined as “differential” because it does not monitor individual pressure levels but rather the difference between two distinct pressure values. When the difference between P2 and P1 exceeds a certain predetermined range, the pressure switch activates.<\/p>\n
Differential pressure switches (PDE) are used to monitor the degree of clogging in a hydraulic filter. If the filter is not clogged, the pressure upstream and downstream is almost identical, while with a clogged filter, there will be a rise in downstream pressure, sufficient to activate the pressure switch. This, thanks to an indicator that changes color from green to red, will signal (visually as well as electrically) the anomaly.<\/p>\n
All our differential pressure switches are equipped with clogging indicators: signaling devices that visually indicate when the switch has activated. In addition to visual signaling, the pressure switch also provides an electrical signal, allowing timely intervention for filter maintenance.<\/p>\n
It is useful for knowing when to replace the filter element because it is clogging. The device monitors the fluid pressure upstream and downstream of the hydraulic filter and alerts when the two pressures start to differ.<\/p>\n
