Are 3300 series and 3500 series modules interchangeable?

In general, 3300 and 3500 series modules are not directly interchangeable because the two systems use different racks, power supplies, and communication architectures. However, many sensors such as proximity probes and extension cables remain compatible. If you are migrating from 3300 to 3500, contact us — we will recommend the right retrofit path and compatible mounting options.

Do you stock spare parts for discontinued 3300/3500 series models?

Yes, we maintain a rotating stock of popular 3300 and 3500 series modules, including several models that Bently Nevada has discontinued. If a module is no longer manufactured, we can help you find a compatible drop-in replacement or an enhanced retrofit option, and we also offer fast emergency supply for critical outages.

How can I get a quote or a retrofit plan?

The fastest way is to use the inquiry cart on any product page, or submit a request through the contact channels on our site. Tell us the model numbers you need and your target quantities. Our team will respond within one business day with pricing, lead time, and — if you are replacing a discontinued model — a compatible retrofit recommendation.

Are your Bently Nevada products genuine and factory-new?

Yes. All modules, probes, and accessories we supply are brand new and original Bently Nevada products, sourced through an authorized channel. Every item comes with its factory serial number and full warranty. We never sell refurbished or cloned parts, so you can rely on the same quality, accuracy, and long service life as factory-direct supply.

Bently Nevada 330709-000-230-50-12-00 3300 XL 11 mm Proximity Probe

High-reliability 5-meter proximity probe for vibration and position monitoring in critical rotating machinery.

Product Introduction

The Bently Nevada 330709-000-230-50-12-00 is a 3300 XL 11 mm Proximity Probe, designed for non-contact vibration and position measurements on rotating machinery. Manufactured in the USA, this probe features an M16 x 1.5 thread, a 230 mm overall case length, and a 5.0-meter cable with a miniature coaxial ClickLoc connector and FluidLoc cable. It is engineered for use with the five-meter Proximitor Sensor only, ensuring optimal system performance.

Parameter Analysis

The 330709-000-230-50-12-00 is a 5-meter probe, specifically matched to a 5-meter Proximitor sensor for accurate signal transmission. The 11 mm probe diameter provides a linear measurement range suitable for most industrial rotating machinery. The probe’s DC resistance of 7.2 ± 0.8 ohms ensures proper impedance matching with the Proximitor. The PPS tip offers excellent chemical resistance and thermal stability, while the stainless steel case provides durability in harsh environments. The ClickLoc connector ensures secure and quick installation.

Application Scenarios

This proximity probe is ideal for monitoring radial vibration, axial position, and shaft eccentricity in critical rotating equipment, including turbines, compressors, pumps, and other rotating machinery. It is commonly used in oil & gas, power generation, and manufacturing industries for predictive maintenance and protection systems.

Installation Guide

Install the probe with the recommended torque of 21.1 N•m (187 in•lb) for the M16x1.5 case. Ensure the thread engagement does not exceed 24 mm. The connector should be finger tight, with a maximum torque of 0.565 N•m (5 in•lb). Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. For optimal performance, the target surface should be at least 30.5 mm in diameter (flat surface) or 152 mm shaft diameter. Observe the temperature limits: exposing the probe below -34°C may cause premature failure of the pressure seal.

Compatibility

This probe is designed for use with the 3300 XL system and is compatible with 5-meter Proximitor sensors (e.g., 3300 XL 11 mm Proximitor). It is not compatible with other cable lengths. The ClickLoc connector mates with standard extension cables and Proximitors.

Maintenance Advice

Regularly inspect the probe tip for damage or contamination. Clean with a soft cloth if necessary. Check cable integrity and connector tightness. Avoid bending the cable beyond the minimum radius. Periodically verify probe resistance (7.2 ± 0.8 ohms) to ensure proper operation.

Procurement Advice

When ordering the Bently Nevada 330709-000-230-50-12-00, confirm the exact model number to ensure correct specifications. Verify the total length (5.0 meters) and connector type. Ensure you have the corresponding 5-meter Proximitor. Consider purchasing spare probes for critical machinery to minimize downtime.
