Product Description
The Bently Nevada 330780-X1-CN is part of the 3300 XL 11 mm Proximity Transducer System, comprising a proximity probe, extension cable, and Proximitor Sensor. It delivers a 3.94 V/mm (100 mV/mil) output, ideal for vibration and displacement measurements in rotating machinery.
Applications
-
Axial (thrust) position measurements
-
Rod position or rod drop on reciprocating compressors
-
Differential expansion on steam turbines
-
Tachometer and zero-speed detection
-
Phase reference (Keyphasor) signals
Key Advantages
-
Extended linear range (up to 4.5 mm) compared to 8 mm systems
-
Rugged construction with TipLoc and CableLoc technology
-
Excellent RFI/EMI immunity
-
DIN-rail or panel mount flexibility
-
Environmentally protected connectors
-
SpringLoc terminal strips for easy wiring

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of the 11 mm over the 8 mm proximity system?
A1: The 11 mm system offers a longer linear range, suitable for applications like axial thrust measurements.
Q2: Can the 330780-X1-CN be used with older 7200 series probes?
A2: No, all components must be upgraded to 3300 XL 11 mm series for compatibility.
Q3: What is the recommended operating temperature for the Proximitor Sensor?
A3: The sensor operates from –52°C to +100°C.
Q4: Is the system suitable for high-RFI environments?
A4: Yes, it features enhanced RFI/EMI immunity and meets CE requirements.
Q5: What type of mounting options are available?
A5: It supports both DIN rail and panel mounting.
Q6: Is the sensor hazardous area approved?
A6: Yes, it is certified for various ATEX, IECEx, and North American standards including SIL2/SIL3 ratings.
Q7: How is the cable secured against oil leakage?
A7: The FluidLoc option prevents oil migration through the cable.
Q8: What is the output scale factor of the sensor?
A8: It provides 3.94 V/mm (100 mV/mil).
Q9: Are special tools required for terminal connections?
A9: No, SpringLoc terminals simplify wiring without specialized tools.
Q10: Can I mix cable lengths and probe lengths?
A10: Yes, but the total length must match the sensor’s system length (e.g., 5 m or 9 m).
