BENTLY 3300/20-12-01-03-00-00 Proximitor Monitor
Product Overview
The BENTLY 3300/20-12-01-03-00-00 is a high-precision Proximitor Monitor designed as a critical component of Bently Nevada’s 3300 Series Machinery Protection System. Engineered to convert proximity probe signals into standardized electrical outputs, this monitor enables real-time measurement of shaft displacement, vibration, and axial position in rotating machinery. As part of the 3300 Series, the 3300/20-12-01-03-00-00 supports seamless integration with other 3300 modules (e.g., vibration monitors, keyphasor modules), forming a comprehensive solution for machinery health monitoring in industries such as oil & gas, power generation, and manufacturing.
Featuring a rugged industrial design, the BENTLY 3300/20-12-01-03-00-00 processes signals from 8 mm proximity probes, providing a measurement range of 0–250 mils (0–6.35 mm) with ±0.5% linearity. Its advanced signal conditioning circuitry includes anti-aliasing filters and galvanic isolation, minimizing electromagnetic interference and ensuring reliable data acquisition in harsh environments. The monitor’s wide operating temperature range (-40°C to +85°C) and IP65-rated enclosure make it suitable for direct installation in demanding industrial settings, while its compatibility with API 670 standards ensures compliance with safety and reliability requirements.
In automation ecosystems, the 3300/20-12-01-03-00-00 serves as the interface between proximity probes and higher-level monitoring systems, converting mechanical movements into 4–20 mA or 0–10 V DC signals for analysis. Its modular design allows easy integration into 3300 Series racks, while built-in LED indicators provide real-time status feedback on signal health and fault conditions. By delivering precise and reliable displacement data, this monitor supports predictive maintenance, reduces unplanned downtime, and extends equipment lifespan in mission-critical applications.
