Quick Detail

Description

The 330780-90-00 3300 XL 11 mm Proximitor Sensor is engineered for high-precision automation and industrial monitoring applications, providing reliable non-contacting vibration and displacement measurements on fluid-film bearing machines. Designed for integration with a single 3300 XL 11 mm Proximity Probe and extension cable, this sensor supports panel mount or high-density DIN-rail installations, offering flexibility for diverse industrial automation setups.

Constructed from A380 aluminum, the Proximitor Sensor ensures durability while maintaining a compact profile. It operates reliably across a wide temperature range from -52°C to +100°C (-62°F to +212°F) and can withstand 100% condensing relative humidity, making it suitable for harsh environments. Enhanced RFI/EMI immunity allows CE-mark compliance without special mounting, ensuring stable operation even near high-frequency radio signals. SpringLoc terminal strips enable fast and robust wiring, minimizing installation time.

The sensor delivers 3.94 V/mm (100 mV/mil) output, offering an extended linear range over standard 8 mm XL systems, and is ideal for applications requiring precise axial, rod, or shaft position measurements. Advanced design features, including patented TipLoc and CableLoc methods, gold-plated ClickLoc connectors, and optional FluidLoc cables, enhance mechanical reliability and prevent fluid ingress, ensuring long-term operation in automated industrial machinery.

Applications

1. Axial (Thrust) Position Measurement
Measures rotor or shaft axial displacement in turbines and compressors with ±0.01 mm resolution, crucial for predictive maintenance and avoiding catastrophic bearing failures.

2. Ramp Differential Expansion in Steam Turbines
Monitors thermal growth and differential expansion in multi-stage turbines, maintaining system efficiency and preventing misalignment damage under varying load conditions.

3. Rod Position or Rod Drop Measurement on Reciprocating Compressors
Tracks precise piston rod movement to prevent mechanical over-travel and improve compressor cycle reliability, enabling automated safety shutdown triggers.

4. Tachometer and Zero Speed Measurement
Provides accurate rotational speed data for control systems, ensuring reliable feedback for automated speed regulation and alignment with Keyphasor signals.

5. Phase Reference (Keyphasor) Signals
Generates precise phase reference signals for vibration analysis, facilitating high-resolution condition monitoring and automated predictive maintenance programs.

Specifications

Competitive Advantage

1. Extended Linear Range
The 11 mm probe tip delivers a longer linear range than the 8 mm system, improving accuracy in large-gap or high-displacement applications.

2. Robust Mechanical Design
Patented TipLoc molding and CableLoc attachment offer 330 N (75 lb) pull strength, reducing the risk of cable detachment and improving system uptime.

3. Environmental Resilience
Rated for extreme temperatures (-52°C to +100°C) and 100% condensing humidity, with optional connector protectors for additional environmental protection.

4. Quick Installation and Wiring
SpringLoc terminal strips and gold-plated ClickLoc connectors facilitate fast, reliable field installation without specialized tools, reducing labor costs.

5. Compatibility and Upgradability
Fully replaces legacy 7200-series 11 mm and 14 mm systems, ensuring seamless integration with updated 3300 XL monitoring configurations while maintaining high automation performance standards.
