Why Choose Our Sensor?
- Plug-and-Play Installation: Pre-calibrated for vertical/horizontal mounting with adjustable setpoints.
- Low Maintenance: No moving parts except the float, minimizing downtime.
- Scalable Solutions: Options for multi-level alarms, analog outputs (4-20mA), or wireless connectivity.
Technical Deep Dive
The sensor’s hermetically sealed reed switch activates when the float’s magnet aligns with the trigger point, ensuring precise switching even in turbulent media. Unlike capacitive or ultrasonic sensors, its mechanical design avoids false readings from foam, vapor, or suspended solids. For air/water interface detection, the float’s density is calibrated to rise only when submerged in liquid, providing fail-safe phase differentiation.
Compliance & Safety
- ATEX/IECEx: Available for Zone 1/21 hazardous areas.
- FDA/USP Class VI: Suitable for pharmaceutical and food-grade applications.
- NEMA 4X: Protection against corrosive environments.
FAQ
Q: Can this sensor handle viscous fluids like slurry or oil?
A: Yes—select a float with a tapered design and low-density material (e.g., NBR) to prevent sticking.
Q: How does it differ from a standard float switch?
A: Standard switches offer single-point triggering, while our continuous float sensor provides real-time level tracking and multi-threshold alerts.
Q: Is calibration required after installation?
A: No—pre-set calibration ensures immediate operation. Optional adjustable brackets allow fine-tuning for unique tank geometries.
Conclusion
For industries prioritizing reliability in liquid and air phase monitoring, the Continuous Float Liquid/Air Water Level Sensor Switch is a cost-effective, maintenance-free solution engineered for precision and durability.
