Technical Abstract
- The 330880-28-15-048-00-02 is an integrated PROXPAC XL Proximity Transducer system designed for high-integrity machinery protection.
- This assembly combines a 3300 XL 8mm probe and a Proximitor sensor within a single, IP66-rated UV-resistant thermoplastic housing.
- By integrating components, it eliminates the need for external housings, making the 330880-28-15-048-00-02 ideal for hazardous or space-constrained locations.
- Featuring a 200 mV/mil scale factor and multiple global approvals, it delivers laboratory-grade displacement data in extreme industrial environments.

Oiltech Controls Limited’s Insight
- The 330880-28-15-048-00-02 is a “best-in-class” solution for Cooling Tower Fans and Hydro Units where moisture is a constant threat.
- The conductive fiber PPS housing is a standout feature, providing the strength of metal with the corrosion resistance of advanced polymers.
- Our engineering team notes that the internal vibration isolation (soft silicone) effectively decouples the probe from housing resonance.
- Ensure the 3/4-14 NPT mounting thread is treated with appropriate sealant to maintain the IP66 integrity of the installation.
Applications & Device Compatibility
- Remote Machinery: Cooling tower gearboxes and fans requiring self-contained sensor protection.
- Hazardous Areas: Direct installation in zones requiring Multiple Approvals (ATEX, CSA, IECEx).
- Reciprocating Equipment: Monitoring rod drop and vibration in large compressors.
- System Integration: Seamlessly feeds Bently Nevada 3500 or Orbit 60 monitoring racks.
Diagnostics & Maintenance
- Static Protection: Integrated grounding liner and conductive housing safely dissipate electrostatic charges.
- Field Wiring Health: Supports up to 305 meters (1,000 feet) of cabling with minimal signal rolloff at high frequencies.
- Mechanical Resilience: The housing is certified for 4 Joule impacts at extreme temperatures, preventing brittle fracture in cold climates.
Shipping & Warranty Terms
- Warranty: 12-Month Quality Guarantee on every 330880-28-15-048-00-02.
- Express Logistics: International door-to-door delivery via FedEx, UPS, and DHL.
