Description:
PALL RC861CZ084HYM is a high-precision differential pressure switch with visual indicator, tailored for industrial hydraulic and lubrication filter systems. It delivers real-time monitoring of differential pressure across filter elements, activating a reliable single-pole double-throw (SPDT) electrical signal once the preset pressure threshold is reached, which prompts timely filter replacement and avoids system malfunctions caused by filter clogging. Featuring a rugged die-cast aluminum housing and fluorocarbon seals, this switch comes with an integrated visual status indicator and a standard Hirschmann DIN43650 connector for effortless electrical integration. Designed to fit PALL filter housings via Deltadyne ports, it maintains consistent performance in harsh industrial environments—resisting high pressure, extreme temperatures, and a wide range of hydraulic fluids—making it a go-to choice for manufacturing, construction machinery, and power generation applications.
Core Advantages:
- Dual Alert Precision: Merges visual indicator and SPDT electrical signal to ensure early detection of filter clogging, preventing delayed maintenance and system damage.
- Heavy-Duty Durability: IP67 protection and aluminum housing enable stable operation in dusty, high-pressure industrial settings, cutting down downtime and replacement expenses.
- Seamless Compatibility: Deltadyne port design and standard Hirschmann connector allow quick assembly on PALL filter housings and easy connection to industrial control systems.
