Key Features
- Precision Sensing: Optimized for low-pressure ranges (0–1 kPa), ensuring high sensitivity for fine pressure adjustments.
- Robust Construction: Features an aluminum die-cast, waterproof housing suitable for harsh industrial environments.
- Versatile Compatibility: Compatible with air, gases, and various non-corrosive fluids (stainless steel wetted parts available for corrosive media).
- High-Reliability Contacts: Gold-plated silver contacts provide stable signal integrity and long-term electrical reliability.
- Ease of Installation: Integrated 3P terminal block wiring allows for straightforward configuration as either a normally open or normally closed switch.
Applications
- Liquid Level Control: Ideal for monitoring and controlling fluid levels in tanks using back-pressure sensing.
- HVAC Systems: Used for differential pressure sensing across air filters and monitoring blower/fan performance.
- Industrial Automation: Suitable for pressure monitoring in pneumatic control circuits and vacuum applications.
- Combustion Systems: Air-flow verification in industrial burners and ventilation ducts.
- Process Control: Reliable switching in low-pressure gas distribution lines.
Compatibility
Compatible with standard industrial pneumatic interfaces. Can be retrofitted into systems requiring precise low-pressure detection. Please check your system’s pressure range against the SPS-5A “A” block range (0-1 kPa).
