Features
- Optimized Deep-Bore Adjustability: Features a 1.0-inch unthreaded portion combined with a 4.4-inch case length, allowing field engineers to easily adjust probe depth inside thick machine walls while avoiding full-thread binding.
- Rugged Mechanical Interface: Built with a premium polyphenylene sulfide (PPS) molded tip and an AISI 303/304 stainless steel case to withstand extreme mechanical abuse.
- Patented Sealing Methods: Uses the advanced TipLoc molding technique for a robust tip-to-case bond and a CableLoc design that provides an exceptional 330 N (75 lbf) pull strength between the case and cable lead.
- Corrosion-Resistant Connection: Equipped with gold-plated brass ClickLoc coaxial terminals that firmly lock with finger-tight torque to eliminate connection loosening from machine vibration.
- Hazardous Area Certified: Comes factory-certified with CSA, ATEX, and IECEx approvals, making it fully ready for safe deployment in explosive industrial zones and Class I, Zone 0 environments.
- High Chemical Resilience: Integrates a built-in Viton O-ring pressure seal to guard the inner cable paths against mild chemical washdowns and fluid tracking.
Functions
- Dynamic Vibration Transduction: Continuously measures dynamic shaft motion (up to 10 kHz frequency response) inside fluid-film bearings to detect unbalance, misalignment, and mechanical looseness.
- Static Displacement Tracking: Monitors slow, static changes in shaft position to provide precise rotor axial thrust readings, preventing catastrophic internal contact between the rotor and stator.
- Non-Contact Distance Measurement: Emits a continuous radio-frequency electromagnetic field from its 8mm tip to determine the gap distance relative to a conductive metal surface without making physical contact.
- API 670 Machinery Protection: Operates as a critical safety input device within larger industrial monitor frameworks, delivering API 670 compliant metrics to trigger machinery alarms or emergency trip logs.
