Differential Pressure Switches

FX Series

Differential Pressure Clogging Indicator

A rugged electrical clogging indicator for pipeline filters, providing a switch signal when differential pressure reaches the configured 1-8 bar set point.

OUTPUTSPDT, 220 VAC / 1 A
MATERIAL304 stainless steel; NBR seal
PROTECTIONIP65

Product overview

Application-focused measurement and switching.

The FX Series is installed across a filter to detect restriction caused by accumulated contamination. When differential pressure reaches the selected value, the indicator can trigger a service alarm or interrupt an associated control circuit. Its design emphasizes switching power, vibration resistance, and immunity to transient startup conditions.

Configuration note

Ratings, materials, interfaces, and approvals can vary by ordered configuration. CASCED US confirms the controlled specification before order acceptance.
