Core Functional Features

1. 11 mm Extended Linear Range

   Delivers a 4.0 mm linear range (50% longer than the 8 mm system), enabling precise measurement of large displacements like axial thrust, steam turbine expansion, and reciprocating compressor rod position—critical for high-tolerance machinery health monitoring.
2. High-Stability Signal Conditioning

   Converts raw eddy current signals into low-noise DC outputs with < 2 mV/V supply sensitivity, ensuring minimal drift and stable readings across temperature and supply variations. Supports simultaneous static position (DC) and dynamic vibration (AC) monitoring.
3. Seamless System Compatibility

   Fully interchangeable with 3300 XL 11 mm probes and extension cables; no field calibration required. Factory-calibrated for AISI 4140 steel (custom options available), ensuring plug-and-play integration with 3300/3500 series machinery protection systems.
4. Robust Industrial Design

   Aluminum housing with IP67 rating, FEP armored cable, and corrosion-resistant components withstand high temperatures, oil mist, moisture, and mechanical shock—ideal for power, oil & gas, and petrochemical plants.
5. Tool-Free Field Wiring

   Equipped with SpringLoc™ terminals for fast, secure connections without special tools, reducing installation time and human error.
6. Wide Environmental Adaptability

   Operates from -40°C to +85°C, with storage down to -55°C, ensuring reliable performance in extreme cold, heat, and humidity conditions common in remote industrial sites.
7. EMI/RFI Immunity

   Advanced shielding and EMC design suppress electromagnetic interference, maintaining signal integrity in high-noise environments like power generation and refineries.
8. Hazardous-Area Ready (Optional)

   Available with ATEX, IECEx, and CSA certifications for safe deployment in Zone 0/1 explosive atmospheres, expanding use cases to offshore platforms and chemical plants.
