Product Overview
The Bently Nevada 330780-A51-CN is part of the 3300 XL 11 mm Proximity Transducer System. It includes a proximity probe, extension cable, and Proximitor Sensor for non-contact measurement of vibration and displacement, especially in high-performance applications like thrust position or rod drop measurements.
Key Applications
-
Axial (thrust) position measurements
-
Ramp differential expansion in steam turbines
-
Rod drop/position on reciprocating compressors
-
Tachometer or zero-speed detection
-
Keyphasor (phase reference) signals
Product Advantages
-
Extended linear range up to 4 mm
-
DIN-rail or panel mount flexibility
-
Enhanced RFI/EMI immunity
-
SpringLoc terminals for tool-free installation
-
Rugged TipLoc and CableLoc designs
-
CE-compliant for industrial use

Frequently Asked Questions (FAQ)
Q1: What is the output sensitivity of the 330780-A51-CN sensor?
A1: The output sensitivity is 3.94 V/mm (100 mV/mil) ±10%.
Q2: What makes the 11 mm version preferable over the 8 mm?
A2: It offers a longer linear range, making it ideal for larger displacement measurements.
Q3: Can this Proximitor Sensor be used with older 7200-series probes?
A3: No. All components must be upgraded to 3300 XL 11 mm for compatibility.
Q4: What is the recommended minimum shaft diameter?
A4: At least 152 mm (6 inches) to minimize cross-talk.
Q5: Is it suitable for high-frequency environments?
A5: Yes. It has high immunity to RFI/EMI and meets CE requirements.
Q6: What installation options are available?
A6: It supports DIN rail and panel mount configurations.
Q7: How long can the field wiring be?
A7: Up to 305 meters (1,000 feet) between sensor and monitor.
Q8: Is the probe cable armored?
A8: Options include armored and unarmored with or without FluidLoc for sealing.
Q9: What is the maximum operating temperature of the probe?
A9: +177°C (351°F).
Q10: What type of applications is this sensor commonly used in?
A10: Steam turbines, compressors, and rotating machinery requiring precise axial/radial monitoring.
