Key Parameters

Core Features & Advantages

• FluidLoc Cable Technology: The module's standout feature is its FluidLoc cable design, which incorporates an internal sealing mechanism to block lubricating oils, water, and process gases from migrating through the cable's internal structure. This is critical in high-pressure bearing housings where fluid leakage through the probe cable would otherwise contaminate the surrounding environment .

• Robust Mechanical Construction: The probe features TipLoc molding for a durable bond between the PPS tip and the stainless steel body, along with CableLoc design offering up to 330 N (75 lbf) of pull strength. These features ensure the probe withstands the mechanical stresses of installation and routing in harsh industrial environments .

• Hazardous Area Approvals: The -05 suffix indicates the module carries CSA, ATEX, and IECEx certifications, making it suitable for installation in potentially explosive atmospheres commonly found in petrochemical plants and oil platforms .

• Complete System Interchangeability: The 3300 XL system supports complete interchangeability of probes, extension cables, and Proximitor sensors. The 1.0-meter probe cable is designed to work with a matching extension cable to form the total system length required by the Proximitor sensor .

Typical Applications

The 330101-00-35-10-11-05 is widely used for critical rotating machinery monitoring across various heavy industries:

• Turbine Shaft Vibration & Position Monitoring: Captures dynamic vibration and axial position of fluid-film bearings in steam and gas turbines

• High-Pressure Process Machinery: Ideal for compressors, pumps, and gearboxes where keeping process fluids or bearing oil contained within the housing is critical (utilizing FluidLoc technology)

• Hazardous Area Machinery Protection: Suitable for petrochemical plants and oil platforms requiring explosion-proof or intrinsically safe monitoring systems

• Retrofitting & Maintenance: Directly replaces older 3300 series 8 mm or 5 mm probes, maintaining full backward compatibility

Frequently Asked Questions (FAQ)

Q1: What is the primary function of the 330101-00-35-10-11-05?

A: It is a non-contact eddy-current proximity probe that measures shaft displacement and vibration on critical rotating machinery. It provides a voltage output proportional to the gap between the probe tip and a conductive target, enabling both static (position) and dynamic (vibration) measurements .

Q2: What is the significance of the FluidLoc cable option?

A: The FluidLoc cable technology prevents oil, process fluids, and other hazardous liquids from migrating through the cable's internal structure. This is essential in high-pressure bearing housings where fluid leakage through the probe cable would otherwise contaminate the surrounding environment .

Q3: What is the recommended installation gap for this probe?

A: The recommended gap is 1.0 mm (40 mils). A healthy system should read between -9 V and -12 V DC at the Proximitor sensor output .

Q4: What are the physical dimensions of this probe?

A: The probe has a 3.5-inch (89 mm) overall case length, 0.0 inches of unthreaded length, a 1.0-meter (3.3 ft) total cable length, and a 3/8-24 UNF thread. It weighs approximately 0.05 kg .

Q5: What is the total system length requirement for this probe?

A: The probe has a 1.0-meter integrated cable. This means it requires a 4.0-meter extension cable (e.g., 330130-040-xx) to form a complete 5.0-meter system when paired with a 5-meter Proximitor sensor. The total electrical length (probe + extension cable) must match the Proximitor's rated system length .

Q6: What should I do if the DC gap voltage reads near -2 V?

A: A reading near -2 V DC typically indicates a shorted probe or cable. Check the probe coil resistance (should be 5–15 Ω for an 8 mm probe) and inspect the cable and connectors for damage or moisture ingress .

Q7: Can this probe be used in hazardous areas?

A: Yes. The -05 suffix indicates the probe carries CSA, ATEX, and IECEx approvals, making it suitable for installation in hazardous locations such as petrochemical plants and oil platforms .

Q8: Is this probe compatible with the 3500 monitoring system?

A: Yes. The 3300 XL 8 mm probe is designed to work with 3300 XL Proximitor sensors, which in turn connect to 3500 series monitor modules (such as the 3500/40M or 3500/42M) for machinery protection and condition monitoring .

Recommended Models & Related Products

The 330101-00-35-10-11-05 is part of the 3300 XL 8 mm Proximity Probe family. Below are related models and required accessories:

Choosing the Right Model

• For high-pressure bearing housings: The 330101-00-35-10-11-05 with FluidLoc cable is the correct choice to prevent oil and process fluid migration .

• For standard installations: The -10-02-05 variant (standard cable, with connector protector) may be suitable if FluidLoc is not required.

• For complete system assembly: Ensure you order the matching 4.0-meter extension cable (330130-040-xx) and a 5.0-meter Proximitor sensor (330180-50-xx) to form a complete 5.0-meter system .
