Product introduction

The 330130-040-01-00 from Bently Nevada is a high-precision proximity probe, representing an enhanced variant in the 3300 series machinery protection system—renowned as the industry standard for monitoring critical rotating equipment. Utilizing advanced eddy current technology, this proximity probe delivers non-contact measurement of shaft displacement, vibration, and position with exceptional accuracy, making it indispensable for protecting high-value machinery in industrial environments.

As an upgraded version of the base 330130 series model, the 330130-040-01-00 offers extended cable length and enhanced environmental protection, making it suitable for larger machinery installations where sensors must be placed at greater distances from monitoring systems. When paired with compatible mounting hardware like the 1X35668 kit and signal conditioners such as the 125720-01, it forms a comprehensive monitoring solution that enables early detection of machinery issues before they lead to costly failures.

Core advantages and technical highlights

Enhanced cable configuration: The 330130-040-01-00 features an extended 7.6m integral shielded cable—significantly longer than standard models—providing greater flexibility in routing around large machinery components. This extended length is particularly valuable for monitoring turbine shafts, large compressors, and other equipment where sensor placement must be distant from control cabinets. The cable’s multi-layer shielding minimizes electromagnetic interference (EMI) and radio frequency interference (RFI) over longer distances.

Superior environmental sealing: This probe incorporates enhanced connector sealing and ruggedized construction that exceeds standard protection levels. The MIL-C-5015 connector features improved O-ring sealing to resist moisture, dust, and chemical ingress, while the cable jacket is reinforced for increased abrasion resistance. These enhancements ensure reliable operation in harsh environments, including those with high humidity, dust, or occasional liquid exposure.

Precision measurement capability: Maintaining the 3300 series’ reputation for accuracy, the 330130-040-01-00 delivers exceptional linearity across its 4.0mm range, with typical error below ±1% of full scale. This precision ensures detection of subtle shaft movements that indicate early-stage machinery problems, such as misalignment, imbalance, or bearing degradation. The probe’s wide frequency response (0Hz to 10kHz) captures both static position and dynamic vibration components.

High-temperature resilience: With an operating temperature range of -54°C to 177°C, the 330130-040-01-00 excels in high-heat environments like gas turbine enclosures, steam turbine auxiliaries, and high-temperature process pumps. Its Inconel probe tip and 316 stainless steel housing resist thermal degradation, maintaining measurement accuracy even under prolonged exposure to extreme temperatures.

Typical application scenarios

In gas turbine power plants, the 330130-040-01-00 is installed at bearing locations along turbine shafts, where its extended cable length allows routing through complex machinery structures to remote monitoring systems. The probe’s high-temperature tolerance withstands the thermal conditions near turbine casings, while its precision measurement capability detects subtle rotor vibrations that indicate early bearing wear or shaft misalignment.

Within petrochemical facilities, the 330130-040-01-00 monitors compressor shafts in hazardous areas, where its ATEX certification ensures safe operation in potentially explosive environments. The enhanced sealing protects against hydrocarbon vapors and process contaminants, while the extended cable length accommodates the large footprint of compressor trains. Data from these probes helps prevent unplanned shutdowns of critical processing equipment.

In large manufacturing facilities, the 330130-040-01-00 provides shaft vibration monitoring for large motors, reducers, and rolling mill equipment. Its extended cable length simplifies installation on machinery where sensor placement must be distant from control systems, while the rugged construction withstands the vibration and contamination typical in heavy industrial environments. The probe’s accurate measurements enable predictive maintenance programs that maximize equipment uptime.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 330130-040-01-00, verify the mounting surface is rigid, clean, and compatible with the 1X35668 mounting kit. Ensure the target shaft material is ferromagnetic and free of surface irregularities that could affect measurements. Plan cable routing to avoid sharp bends (minimum 15mm static radius), high-temperature areas exceeding 177°C, and EMI sources. For hazardous area installations, confirm the location classification matches the probe’s ATEX Zone 2 rating.

Mounting procedure: Secure the 1X35668 mounting bracket to a rigid surface near the monitoring point, ensuring stability during machinery operation. Attach the 330130-040-01-00 probe to the mounting hardware, adjusting position to achieve the target gap (typically 0.5mm-1.0mm). 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 proper strain relief to prevent cable damage. Secure connector mating using proper torque specifications.

Maintenance suggestions: Inspect the 330130-040-01-00 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 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.
