Bently Nevada 330904-04-14-10-12-05 Probe | 40mm Unthreaded Armored

Extended Length Sensor with Fluid-Resistant Cable

The Bently Nevada 330904-04-14-10-12-05 is a specialized 3300 NSv Proximity Probe. It features a long 40mm unthreaded body section and FluidLoc cable. This design is ideal for mounting through thick machine casings or brackets.

The armored cable provides physical protection, while FluidLoc construction resists oils and coolants. Ensure reliable monitoring in wet or washdown industrial environments.

Installation for Thick Wall Mounting

The 40mm unthreaded section allows the probe to pass through a deep mounting hole or spacer before the threads engage. Set the 1.0 mm air gap precisely after full installation. Route the FluidLoc cable away from direct fluid streams where possible.

Diagnostic Function & Typical Use

Accurately measures:

• Shaft relative displacement (vibration)
• Axial thrust position
• Rotor dynamic behavior
• Casual pre-failure conditions like rubs

Ideal Applications: Machinery with deep bearing housings, gearboxes, compressors in oily environments, food & beverage processing with washdown, and any application requiring fluid-resistant cabling.

Approvals & Logistics

• Certified for use in explosive atmospheres (Multiple EPL Ratings)
• Rated for wide ambient temperature ranges (T1-T5)
• Package Includes: 1 x Complete armored probe assembly.
• Shipping Methods: Fast international delivery via FedEx, UPS, or DHL.

Professional FAQs

What is the purpose of the 40mm unthreaded length?

It allows the probe body to pass through a thick mounting flange, spacer, or housing before the threads start. This is used when the measurement point is recessed behind a significant thickness of material.

What makes FluidLoc cable different?

FluidLoc cable has a special outer jacket formulation that resists swelling, cracking, and degradation from exposure to industrial oils, synthetic lubricants, and coolants, unlike standard PVC jackets.

What is the lead time and shipping cost?

Items are typically in stock for quick dispatch. Shipping costs depend on destination and service (FedEx/UPS/DHL). Contact us for an exact quote with delivery time.

What does the 12-month warranty cover?

The warranty protects against failures due to material or workmanship defects under normal use for one year from the invoice date.

Any installation tip for the extended unthreaded section?

Ensure the clearance hole for the unthreaded section is clean and smooth. Burrs or dirt can scrape the O-ring as the probe is inserted, potentially damaging the seal before the threads even engage.

Can the FluidLoc jacket withstand steam cleaning?

While resistant to many fluids, high-pressure, high-temperature steam cleaning may still degrade the jacket over time. It is best to shield the cable from direct, sustained steam jets during cleaning procedures.

Is This Your Model?

Select the 330904-04-14-10-12-05 when you need an armored probe with a long unthreaded section for deep mounting AND a fluid-resistant cable. It is the specialist choice for challenging mechanical and environmental conditions.
