Quick Detail

Description

The 330878-90-05 3300 XL 50 mm Proximitor Sensor is a high-precision proximity monitoring solution designed for industrial automation and machinery protection. This self-contained Proximitor sensor assembly integrates a 3300 XL 50 mm non-contacting Proximity Probe and its corresponding extension cable, delivering accurate vibration and displacement measurements over a linear range of 27.9 mm (1100 mils). Constructed from A380 aluminum, the sensor operates reliably in extreme temperatures from -51°C to +100°C (-60°F to +212°F) and supports field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) using a three-conductor shielded triad cable. The assembly’s panel mount option enables a total system length of 9.0 metres (29.5 feet), facilitating flexible installation in complex industrial setups. With multiple agency approvals and a robust output resistance of 50 Ω, the 3300 XL Proximitor Sensor ensures seamless integration into condition monitoring and automation systems. Its advanced design eliminates the need for a separate Proximitor housing, reducing wiring complexity and enhancing system reliability for critical rotating machinery monitoring in harsh industrial environments.

Applications

1. Turbomachinery Vibration Monitoring
The 3300 XL 50 mm Proximitor Sensor accurately detects shaft displacement and vibration in turbines, compressors, and generators, providing real-time feedback to automation systems. Its linear range of 27.9 mm ensures precise measurement of rotor motion, enabling predictive maintenance in high-speed machinery.

2. Industrial Automation Control
Integrated directly into control panels, the Proximitor sensor allows automation systems to monitor equipment conditions continuously. The panel mount option and field wiring compatibility (16–24 AWG triad cable) facilitate easy integration into PLC or DCS frameworks, ensuring operational efficiency.

3. Harsh Environment Machinery Protection
The sensor’s PPS housing with Type 4X and IP66 ratings provides reliable operation in extreme environments, including high humidity, dust, and chemical exposure. Operating temperature from -51°C to +100°C ensures stable performance in oil, gas, and petrochemical plants.

4. Rotating Equipment Diagnostics
By combining a 3300 XL Proximity Probe with the integrated Proximitor sensor, the assembly simplifies diagnostics of rotating machinery. Real-time displacement readings enable engineers to detect imbalance, misalignment, or bearing wear, reducing unplanned downtime.

5. Condition-Based Maintenance Systems
The sensor feeds accurate vibration and proximity data into predictive maintenance platforms. With its self-contained design eliminating extension cables, installation is streamlined, and signal integrity is preserved for automated alerts and historical trend analysis.

Specifications

Competitive Advantage
