The 330180-90-00 is part of the 3300 XL Proximitor Sensor series from Bently Nevada, a high-precision vibration and position measurement solution used in critical rotating machinery. It’s engineered to monitor both static and dynamic motion (e.g., shaft vibration, position, speed, and Keyphasor signals) in machines with fluid-film bearings like turbines, compressors, and pumps.
This model is designed to be used with 3300 XL probes and extension cables to form a complete proximity transducer system. It features a system length of 9.0 meters, panel mount configuration, and voltage output proportional to the distance between the probe tip and the target.

Q1: Is the 330180-90-00 still in production?
A1: While some sources list it as discontinued, it is widely available through aftermarket and industrial suppliers. It’s still a staple in many facilities due to its compatibility and reliability.
Q2: Can I use older 3300 series probes with this module?
A2: Yes. It is compatible with both legacy and XL versions of 5 mm and 8 mm probes and extension cables. However, performance is optimized with XL components.
Q3: What is the output signal of this sensor?
A3: The sensor outputs a linear voltage signal proportional to the gap between the probe and the target. Typical sensitivity is 7.87 V/mm.
Q4: What material should the target be made of?
A4: The system is calibrated for AISI 4140 steel. Using other materials may affect linearity and sensitivity.
Q5: Can it be used in high-temperature environments?
A5: Yes, but within industrial temperature ranges. For extremely high temperatures, consider the 330780 series or sensors with extended temperature certifications.
Q6: What is the recommended probe gap setting?
A6: Around 1.27 mm (50 mils) is typical. Incorrect gaps can cause signal saturation or nonlinear outputs.
Q7: Does it support Keyphasor signal generation?
A7: Yes. It is often used in setups that require Keyphasor signals for shaft phase or speed reference.
Q8: What happens if I use a non-standard target material?
A8: Output voltage may deviate from expected values, affecting measurement accuracy. Always validate against calibration standards.
Q9: Does this sensor require agency certifications like ATEX or CSA?
A9: No, this specific model does not require additional agency approvals. It simplifies installation in non-hazardous zones.
Q10: What are common failure points in this system?
A10:
Loose probe or extension cable connections
Incorrect gap settings
Power supply issues
Electromagnetic interference (EMI)
Surface corrosion on target
Improper shielding or grounding
Routine maintenance and inspections can mitigate these issues.
