Description:
PALL RC861CZ084HSSYM is a high-precision differential pressure switch with visual indicator, engineered specifically for industrial hydraulic and lubrication filter systems. It offers real-time monitoring of differential pressure across filter elements, activating a dependable single-pole double-throw (SPDT) electrical signal when the preset low-pressure threshold is exceeded, which prompts timely filter replacement and prevents system malfunctions caused by filter clogging. Constructed with a rugged die-cast aluminum housing and fluorocarbon (FKM) seals, this switch comes with an integrated visual status indicator and a standard Hirschmann DIN43650 connector for seamless electrical integration. Designed to mount directly on PALL filter housings via Deltadyne ports, it maintains stable performance in harsh industrial environments—resisting high pressure, extreme temperatures, and a broad range of hydraulic fluids—making it a reliable choice for manufacturing, construction machinery, and power generation applications.
Core Advantages:
- Dual Alert Precision: Combines visual indicator and SPDT electrical signal to ensure early detection of filter clogging, eliminating risks of delayed maintenance and system damage.
- Heavy-Duty Durability: IP67 protection and die-cast aluminum housing enable stable operation in dusty, high-pressure industrial settings, cutting down downtime and replacement costs.
- Seamless Compatibility: Deltadyne port design and standard Hirschmann connector allow quick assembly on PALL filter housings and easy connection to industrial control systems.
