Product introduction

The 330130-040-00-00 from Bently Nevada is a high-performance proximity probe, representing a core component of the 3300 series machinery protection system—widely recognized as the industry standard for monitoring rotating equipment. Utilizing advanced eddy current technology, this proximity probe provides precise non-contact measurement of shaft displacement, vibration, and position in critical industrial machinery.

As a foundational element in machinery health monitoring, the 330130-040-00-00 delivers reliable gap-to-voltage conversion, translating physical shaft movement into actionable electrical signals for analysis by monitoring systems. Its 4.0mm measurement range makes it ideal for applications requiring moderate displacement monitoring, such as motor shafts, pump rotors, and compressor journals. When paired with compatible signal conditioners and mounting hardware like the 1X35668 kit, the 330130-040-00-00 forms an essential part of predictive maintenance programs, enabling early detection of machinery issues before they lead to catastrophic failures.

Core advantages and technical highlights

Precision measurement capability: The 330130-040-00-00 delivers exceptional linearity across its 4.0mm range, with a typical error of less than ±1% of full scale. This precision ensures accurate measurement of subtle shaft movements that indicate early-stage machinery problems, such as misalignment, imbalance, or bearing wear. The probe’s wide frequency response (0Hz to 10kHz) captures both static position and dynamic vibration components, providing comprehensive machinery health data.

Extreme environment durability: Constructed with an Inconel probe tip and stainless steel housing, the 330130-040-00-00 withstands harsh industrial conditions, including high temperatures up to 177°C and exposure to corrosive substances. Its rugged design resists vibration, shock, and mechanical damage, ensuring reliable operation in demanding environments like power plant turbine enclosures, chemical processing facilities, and offshore platforms.

Integrated signal integrity: The 330130-040-00-00 features an integral shielded cable that minimizes electromagnetic interference (EMI) and radio frequency interference (RFI), preserving signal integrity even in electrically noisy environments. The probe’s stable output characteristics reduce drift over time and temperature, maintaining measurement accuracy without frequent recalibration. This reliability is critical for long-term trend analysis in predictive maintenance programs.

Typical application scenarios

In pulp and paper mills, the 330130-040-00-00 is installed on papermachine rolls and dryer cylinders to monitor shaft runout and vibration. Mounted using the 1X35668 hardware kit, the probe detects subtle misalignments that can cause paper web defects or roll damage. Its resistance to moisture and paper dust ensures consistent performance in the humid mill environment, providing data to optimize roll alignment and extend equipment life.

Within chemical processing plants, the 330130-040-00-00 monitors agitator shafts and mixer rotors, where precise position measurement helps prevent seal wear and shaft rubs. The probe’s chemical-resistant construction withstands exposure to process vapors and cleaning agents, while its wide temperature range accommodates the thermal conditions near reaction vessels. By continuously measuring shaft movement, it provides early warning of bearing degradation in critical mixing equipment.

In power generation facilities, the 330130-040-00-00 is deployed on auxiliary machinery such as boiler feed pumps and cooling tower fans. Its reliable performance in high-vibration environments ensures accurate measurement of pump shaft position, enabling detection of impeller imbalance or bearing failure before these issues affect power plant operations. The probe’s compatibility with 3500 series monitoring systems allows integration into plant-wide machinery health networks.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 330130-040-00-00, ensure the mounting surface is properly prepared and compatible with the 1X35668 mounting kit. Verify that the target shaft material is ferromagnetic (non-magnetic materials require special consideration). Plan cable routing to avoid sharp bends, high-temperature areas, and sources of electromagnetic interference. Ensure the installation area allows for the recommended 0.5mm-1.0mm initial gap between probe tip and shaft surface.

Mounting procedure: Secure the 1X35668 mounting bracket to a rigid surface near the monitoring point, ensuring stability during machinery operation. Attach the 330130-040-00-00 probe to the mounting hardware, adjusting position to achieve the target gap. Use a digital multimeter to verify proper output voltage (-2V to -10V) corresponding to the gap setting. Route the integral cable to the signal conditioner or junction box, maintaining the minimum bend radius (15mm static, 30mm dynamic) to prevent cable damage. Secure connections using proper torque specifications for MIL-C-5015 connectors.

Maintenance suggestions: Inspect the 330130-040-00-00 quarterly for physical damage, particularly to the probe tip and cable insulation. Clean the probe tip with a soft cloth if contaminated, taking care not to scratch the Inconel surface. Verify gap voltage periodically to ensure it remains within specification, adjusting if necessary using the 1X35668 mounting hardware. Check cable connections for corrosion or looseness, especially in humid environments. Perform annual calibration using the 330180-91-CN tool to maintain measurement accuracy.
