Description:
PALL RC861CZ091ZYM is a high-precision differential pressure switch with integrated visual indicator, specially designed for industrial hydraulic and lubrication filter systems. It provides real-time monitoring of differential pressure across filter elements, triggering a reliable single-pole double-throw (SPDT) electrical signal when the preset pressure threshold is exceeded, while the built-in visual status light offers intuitive on-site fault reminders. Constructed with a rugged die-cast aluminum housing and fluorocarbon (FKM) seals, this switch features a standard Hirschmann DIN43650 connector and is fully compatible with PALL filter housings via Deltadyne ports. It delivers stable performance in harsh industrial environments, resisting high pressure, extreme temperatures, and a wide range of hydraulic fluids, making it an ideal choice for manufacturing, construction machinery, and power generation applications to safeguard system cleanliness and minimize unplanned downtime.
Core Advantages:
- Dual Alert Reliability: Merges electrical signal output for remote control systems and visual indicator for on-site maintenance, ensuring filter clogging is detected promptly without omission.
- Heavy-Duty Durability: IP67 protection and corrosion-resistant aluminum housing enable stable operation in dusty, high-vibration industrial settings, extending service life and reducing replacement costs.
- Seamless Compatibility: Deltadyne port design and standard Hirschmann connector allow quick assembly with PALL filter housings and easy connection to PLC/DCS control systems, minimizing installation time.
