Description

The 330780-51-00 3300 XL 11 mm Proximitor Sensor is a high-performance transducer designed for precise non-contacting vibration and displacement measurements in industrial automation systems. Compatible with 3300 XL 11 mm Proximity Probes and extension cables, this sensor delivers a 3.94 V/mm (100 mV/mil) output across fluid-film bearing machines, ensuring accurate measurement of rotor displacement, axial position, and Keyphasor reference signals. Constructed with durable A380 aluminum and tested for harsh industrial environments (-52°C to +100°C operating range), the sensor is suitable for DIN-rail or panel-mounted installations. Enhanced RFI/EMI immunity supports CE mark compliance and prevents interference from high-frequency electrical noise. The patented TipLoc and CableLoc designs ensure robust mechanical and electrical connections, while optional FluidLoc cables and connector protectors prevent oil and moisture ingress. With a 5.0-meter system length and support for various probe threads, the 3300 XL 11 mm Proximitor Sensor provides reliable, high-resolution performance for demanding machinery monitoring and predictive maintenance applications.

Applications

Axial and Thrust Position Measurements
Used in steam turbines and large compressors, the 3300 XL 11 mm Proximitor Sensor precisely measures axial rotor displacement up to 2 mm linear range, supporting safe operation and early fault detection.

Differential Expansion Monitoring
Monitors ramp differential expansion in high-speed turbines or generators, providing real-time displacement data critical for thermal expansion management and rotor alignment.

Rod Position and Rod Drop Detection
Installed on reciprocating compressors, the sensor accurately tracks rod movement and drop events, preventing mechanical failures and improving maintenance scheduling.

Tachometer and Zero Speed Measurement
Provides reliable speed reference signals in fluid-film bearing machines, enabling synchronization and safe start/stop operations, with minimal drift even under high vibration conditions.

Phase Reference (Keyphasor) Signals
Generates accurate Keyphasor pulses for vibration analysis, condition monitoring, and rotor balancing, ensuring alignment with API 670 standards in predictive maintenance systems.

Specifications

Input :	Accepts one non-contacting 3300 XL 11 mm Proximity Probe and Extension Cable.
Power :	Requires -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption, -23 Vdc to -26 Vdc with barriers. Operation at a more positive voltage than -23.5 Vdc can result in reduced linear range.

Field Wiring:	0.2 to 1.5 mm2 (16 to 24 AWG) [0.25 to 0.75 mm2 (18 to 23 AWG) with ferrules]
Storage Temperature:	-52°C to +105°C (-62°F to +221°F)
Operating Temperature:	-52°C to +100°C (-62°F to +212°F)
Relative Humidity:	100% condensing, nonsubmersible when connectors are protected. Tested to IEC 68-2-3 damp heat.
Supply Sensitivity:	Less than 2 mV change in output voltage per volt change in input voltage.
Output resistance:	50 Ω

Competitive Advantage

Extended Linear Range
The 11 mm probe tip allows a longer linear range than standard 8 mm systems, enabling precise measurements on larger shafts or higher amplitude vibration applications.

Durable Construction and Temperature Resistance
A380 aluminum housing with high chemical and thermal resistance supports operation from -52°C to +100°C, suitable for harsh industrial environments.

Robust Electrical and Mechanical Connections
Patented TipLoc and CableLoc designs provide 330 N pull strength and prevent detachment or signal loss, ensuring reliable performance even under high vibration and torque loads.

Enhanced RFI/EMI Immunity
Shielded design and CE-compliant RFI/EMI performance prevent interference from nearby high-frequency equipment, ensuring consistent signal integrity in automated plants.

Flexible Installation and Upgrade Compatibility
Supports multiple probe threads, DIN-rail, or panel mounting configurations, and fully compatible with 3300 XL transducer systems, allowing seamless upgrades from legacy 7200-series sensors.
