SPS14 Pressure switch for water purifier
This product is specifically designed for water purifiers.
SPS14 Differential Pressure Switch for Water Purifier
The SPS14 differential pressure switch is specially engineered for modern water purifiers, offering a sensitive response and expanded operational range that effectively replaces traditional high/low pressure switches. It integrates high-sensitivity pressure sensors on both sides and utilizes bellows-based pressure transfer, ensuring stable linear pressure coefficients and extended lifespan. The device is suitable for automatic or manual reset, with customizable mounting options and interface types to meet varied installation needs.
Key Specifications:
• Core Function: Differential pressure sensing and control for water purification systems
• Sensor Technology: Dual-side sensitive pressure sensors with bellows for linear and stable response
• Output Mode: Mechanical switching – SPST-NO or SPST-NC (customizable)
• Pressure Setting Range: 0.02–1.0 MPa (configurable; <0.6 MPa as low, ≥0.6 MPa as high)
• Operation Mode: Automatic or manual reset options available
• Protection Rating: IP54 (splash-proof, dust-resistant)
• Electrical Connection: Wire leads, blade terminals, or custom insert rod
• Process Interface: Plastic housing, replaceable joint section (10–40mm)
• Rated Load:
AC: 24–250V, 0.02–6A
DC: 8–36V, 0.02–3A (max 0.5A for longevity)
Typical Applications:
✔ Replacement for high/low pressure switches in water purification systems
✔ Automated control of bypass valves in pumps and pipe loops
✔ Monitoring and managing differential pressure in household or commercial water/oil circulation systems
✔ Applicable in systems requiring compact design, high sensitivity, and long-term switching reliability
