Key Features & Benefits

1. Superior Sensor Technology
   • 99.9% High-Purity Alumina Ceramic (Ceraphire) Sensor: Offers outstanding resistance to corrosion, abrasion, and mechanical overload. It is inherently vacuum-proof and provides excellent long-term stability with zero drift.
   • Oil-Free Design: Eliminates the risk of oil contamination to the process media, critical for drinking water and food-grade applications.
   • Overload Protection: Withstands up to 40 bar (600 psi) overpressure, ensuring survivability in surge conditions.
2. High Precision & Smart Compensation
   • Reference Accuracy: Standard ±0.2% of calibrated span; Platinum version available with high-precision ±0.1% accuracy.
   • Automatic Density Compensation: Integral temperature measurement (via optional Pt100 sensor) allows for dynamic correction of liquid density variations, ensuring optimal accuracy across fluctuating process temperatures.
   • Simultaneous Level & Temperature Measurement: Provides two critical process variables from a single process penetration.
3. Versatile Communication & Configuration
   • Output Signal: 2-wire, 4-20 mA analog with superimposed HART 6.0 protocol. The signal can be inverted for special applications.
   • Flexible Scaling: Measuring ranges are fully field-configurable via HART communicator or software, supporting units such as mH2O, ftH2O, bar, psi, %, and more.
4. Robust Construction & Versions
   • Three Optimized Versions:
     • 22 mm (0.87") Stainless Steel: Slim design for drinking water, boreholes, and narrow wells.
     • 42 mm (1.65") Stainless Steel: Heavy-duty, flush diaphragm for easy cleaning in wastewater and sludge applications.
     • 29 mm (1.14") Plastic/Polymer: Non-metallic, saltwater-resistant version ideal for marine and brackish water applications.
   • Process Connections: Includes suspension clamps and cable glands for simple, secure installation.
   • Cable Options: High-quality PE, PUR, or FEP cables for chemical resistance and long-term submersion.
   • Climate-Proofed: Fully potted electronics and a dual-filter pressure compensation system protect against humidity and environmental extremes.
