Description:
PALL RC861CZ090HYM is a high-precision differential pressure switch with integrated visual indicator, engineered for critical monitoring of industrial hydraulic and lubrication filter systems. It delivers real-time detection of differential pressure across filter elements, triggering a reliable single-pole double-throw (SPDT) electrical signal when the preset threshold is exceeded, while its built-in status light provides intuitive visual confirmation for on-site maintenance teams. Constructed with a rugged die-cast aluminum housing and fluorocarbon (FKM) seals, this switch is optimized for direct mounting on PALL filter housings via Deltadyne ports, ensuring stable performance in harsh environments—including high pressure, extreme temperatures, and exposure to diverse hydraulic fluids. It is a trusted solution for manufacturing, construction machinery, and power generation applications, safeguarding system cleanliness and minimizing unplanned downtime.
Core Advantages:
- Accurate Pressure Monitoring: The preset differential pressure set point with a small tolerance range ensures timely and accurate feedback on the filter element blocking status, preventing excessive pressure drop from damaging the system.
- Reliable Switching Performance: The SPDT switch design can flexibly connect to alarm circuits, control systems, etc., and the automatic reset function is convenient for system warm - up monitoring, avoiding false alarms caused by high - viscosity fluids at low temperatures.
- Durable & Stable: Adopting industrial - grade materials and reliable connector design, it can work stably for a long time in harsh industrial environments such as high temperature, vibration and humidity, and has low maintenance costs.
