Ceramic Tuning Fork Density Meter — LONN-700C for Abrasive Slurry Applications
LONN-700C ceramic tuning fork density meter: ±0.002 g/cm³ accuracy in abrasive slurry.
Ceramic fork tines (1200+ HV) resist sand/mineral erosion.
Non-nuclear design eliminates radioactive licensing.
4-20mA + RS485; ANSI/DIN/JIS flange or tri-clamp.
LONNMETER serves 130+ countries.
- ✅ Superior Abrasion Resistance: Ceramic fork tines (1200+ HV) withstand sand, mineral ore, and tailings particles that destroy standard metal fork surfaces — extending sensor service life by 5-10× in slurry service
- ✅ Proven ±0.002 g/cm³ Accuracy: Ceramic fork tines add zero interference to vibration frequency — accuracy identical to standard polished fork configuration
- ✅ Wide Slurry Compatibility: Handles particles up to 50μm diameter, suspended solids up to 40%, and gas content up to 20% — suitable for most mineral processing and mining slurry circuits
