The differential pressure indicator is a detection device mounted on hydraulic filters to real-time monitor the pressure difference across filter elements. When contamination buildup on the filter element causes the pressure differential to reach the preset threshold, the indicator triggers a mechanical or electrical alarm signal to alert operators to replace the filter element promptly. This effectively safeguards the hydraulic system and prevents equipment malfunctions resulting from clogged filter cartridges.
