Key FeaturesVOGI
Extreme Environment Compatibility: The Epro PR9268/302-000’s IP69K-rated 17-4PH steel housing withstands 250 bar CIP spray and -55°C arctic freezer vibrations in pharmaceutical plants, and MIL-STD-810H certification verifies 50G shock tolerance in mining crushers.
Triaxial Accuracy: ±0.5% velocity accuracy in the 0.5Hz–10kHz range captures displacements below 1μm – proven in Japan Shinkansen wheel hub monitoring 320km/h harmonic mode.
Smart Connectivity: The Epro PR9268/302-000’s integrated PoE (802.3af) and OPC UA Pub/Sub protocols enabled a German hydrogen compressor station to reduce false alarms by 42% through real-time SCADA integration.
Rapid Deployment: Epro PR9268/302-000 tool-free magnetic bracket enables sensor replacement in <90 seconds - deployed on 37 Chilean copper slurry pumps during a planned outage in 2023.
Hazardous Area Ready: ATEX Zone 1/21 compliance detected a bearing failure in a Saudi refinery turbine more than 600 hours before the disaster and withstood 180°C ambient heat and H2S exposure.

APPLICATIONVOGI
Copper Electrorefining Tankhouses: At a Chilean mine, 28 units monitored crane rail vibrations despite 98% humidity and acid mist. MODBUS TCP alerts correlated 8–12Hz harmonics with cathode plate warping, cutting replacement costs by $1.2M annually.
Hydrogen Compression Stations: A German energy firm deployed explosion-proof variants (ATEX Zone 1) on 5,000psi compressors. The sensor’s H₂-resistant coating detected valve seat wear 600+ hours pre-failure via 0.01g resolution.
High-Speed Rail Axle Boxes: In Japanese Shinkansen depots, sub-zero-rated models (-55°C) analyzed 320km/h wheel vibrations. Machine learning integration flagged bearing defects with 94% accuracy, reducing inspection downtime by 40%.
Tidal Turbine Foundations: Scottish marine engineers used subsea variants (100m depth rating) to monitor 16MW turbine moorings. Anti-biofouling probes detected structural fatigue patterns 14 months before traditional methods.
EPRO PR9268/302-000: A rugged vibration sensor designed for industrial turbines and compressors, delivering precise 4-1000Hz monitoring with 28.5mV/mm/s sensitivity in extreme conditions up to 200°C, ideal for power plants and oil refineries requiring API 670 compliance.
