Quick Detail

Description

The Bently Nevada 3300 XL 8mm Proximity Sensor Probe (128987-130-01-05) is a precision industrial automation sensor engineered for high-performance vibration and position monitoring in rotating machinery. Designed for non-contact displacement measurement, this probe provides highly accurate detection of shaft movement, vibration, and rotational position. With a measuring range of 0.25 to 1.0 mm and accuracy of ±0.5% of full scale, it ensures reliable monitoring even in critical machinery applications. Its repeatability of ±0.2% and frequency response up to 10 kHz allows the sensor to capture rapid shaft vibrations and transient events with exceptional precision.

Built for industrial reliability, the 3300 XL probe operates in extreme temperatures from -40°C to +85°C, with extension cables rated from -51°C to +177°C, making it suitable for harsh operational environments. The sensor outputs a 4–20 mA signal, compatible with standard SCADA and DCS systems for seamless automation integration. Designed to work with Bently Nevada supplied AlSI 4140 steel targets of 61 mm diameter or larger, and a probe gap of 7 mm (275 mils), the 3300 XL probe ensures consistent and accurate monitoring in applications requiring high precision and robust performance.

Applications

1. Turbomachinery Shaft Vibration Monitoring
The 3300 XL probe accurately tracks shaft displacement in turbines, compressors, and generators, enabling early detection of misalignment or imbalance. Frequency response up to 10 kHz ensures fast transient events are captured, improving predictive maintenance efficiency.

2. High-Speed Rotating Equipment
Ideal for pumps, fans, and motors, the probe provides real-time displacement data to prevent catastrophic failures. Using a 4–20 mA output, data integrates directly into automated control systems for immediate response.

3. Condition-Based Maintenance Programs
The sensor supports non-contact vibration analysis, reducing manual inspections and allowing condition-based maintenance schedules that can reduce unplanned downtime by up to 20% in industrial plants.

4. Precision Position Sensing
The 3300 XL ensures accurate shaft position detection with a probe gap of 7 mm, crucial for applications in high-speed centrifuges and critical process equipment.

5. Harsh Environment Industrial Automation
Operating from -40°C to +85°C and with high-temperature cable tolerance, it functions reliably in extreme industrial settings such as petrochemical plants, power generation facilities, and steel mills.
