PFMB7202-06-D: Precision Sensing, Intelligent Start-Stop! Flow Switches Empower Safety Monitoring in Fluid Systems
2025-09-09
Core Product Advantages
- 1.High-Precision Flow Detection
• Utilizes turbine or piston sensing mechanisms to monitor fluid flow in real time, with triggering accuracy up to ±5% FS. Reliably detects ultra-low flow rates (e.g., 0.1 L/min).
- 1.Adjustable Triggering Threshold
• Supports customizable flow setting ranges (e.g., 1–30 L/min). Flexible adjustment via knobs or DIP switches to adapt to diverse operational needs.
- 1.Passive Contact Output
• Provides SPDT mechanical contacts (dry contacts), compatible with PLCs, controllers, and other devices. No external power supply required, ensuring simple and reliable wiring.
- 1.Pressure- and Corrosion-Resistant Structure
• Valve body made of brass or stainless steel, with seals in NBR/Viton. Pressure rating ≥1.6 MPa, suitable for various media such as water, oil, and air.
- 1.Low Flow Resistance Design
• Optimized internal flow channel ensures pressure loss <0.1 bar, minimizing impact on system flow.
Typical Application Scenarios
•
Cooling System Monitoring: Detects abnormal cooling water flow to prevent equipment overheating.
•
Lubrication System Protection: Monitors lubricating oil flow and triggers low-flow alarms.
•
Pump Dry-Run Protection: Detects flow at pump outlets to avoid damage from dry operation.
•
Energy Management: Enables flow-linked control in HVAC/heating systems.
