Main Features

Core Features & Advantages

• FluidLoc Cable for Fluid Ingress Protection: The module’s standout feature is its FluidLoc cable option (Code 12), which incorporates internal sealing 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.

• Reverse Mount Design for Space-Constrained Installations: The reverse mount configuration allows the probe to be installed from the rear side of a housing or bracket, with the cable exiting opposite the measurement surface. This makes it ideal for installations with limited rear access, such as inside bearing housings or gearboxes, where standard probes cannot fit.

• Robust Construction for Harsh Environments: The probe features a PPS tip for chemical resistance, an AISI 303/304 stainless steel case, and a Viton O-ring to prevent moisture and dust ingress. The cable includes a CableLoc system providing up to 330 N (75 lbf) of pull strength, and gold-plated ClickLoc connectors for corrosion resistance and reliable signal transmission.

• 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 4.0-meter extension cable to form a complete 5.0-meter system when paired with a 5-meter Proximitor sensor.

Typical Applications

The 330106-05-30-10-12-00 is widely used for critical rotating machinery monitoring in demanding industrial applications:

• Steam Turbines and Hot Gas Compressors: Vibration and position monitoring in high-temperature environments where the ETR version operates up to +218°C

• Centrifugal Compressors: Shaft displacement tracking in high-pressure bearing housings

• Industrial Pumps and Gearboxes: Vibration monitoring where rear-side installation is required

Frequently Asked Questions (FAQ)

Q1: What does the model number “330106-05-30-10-12-00” indicate?
A: The breakdown is: 330106 = 3300 XL 8 mm Reverse Mount Probe with 3/8-24 UNF thread; -05 = 0.5 in unthreaded length; -30 = 3.0 in case length; -10 = 1.0 meter cable; -12 = Miniature ClickLoc connector with FluidLoc cable; -00 = No agency approvals.

Q2: When should I choose the Reverse Mount version over a standard probe?
A: Reverse mount probes are used when the installation requires the probe to be inserted through a housing (such as the Bently Nevada 21000 series) or when there is limited clearance for standard front-mount installation.

Q3: What is the advantage of the FluidLoc cable option?
A: The FluidLoc cable (Option 12) is designed with internal seals to prevent oil, coolants, or other process fluids from leaking through the inside of the cable and into the Proximitor sensor or junction box. This is essential in high-pressure bearing housings.

Q4: Can this 1.0-meter probe be used with a 4.0-meter extension cable?
A: Yes. The 1.0-meter probe cable requires a 4.0-meter extension cable 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.

Q5: What is the recommended installation torque for this probe?
A: Torque the probe into the housing to approximately 4.5 N·m (40 in·lb). Over-tightening can damage the internal sensor coil or the thin-wall section of the 8 mm tip.

Q6: Does this probe require agency approvals for hazardous areas?
A: This specific model (-00 suffix) has no agency approvals and is suitable for general-purpose environments only. For hazardous area installations, select a variant with the appropriate approval suffix (e.g., -05 for CSA, ATEX, IECEx).

Q7: What are the key troubleshooting steps 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 7.59 ± 0.50 Ω for a 1.0 m probe) and inspect the cable and connectors for damage or moisture ingress.

Choosing the Right Model

• For fluid-tight applications: The 330106-05-30-10-12-00 with FluidLoc cable is the correct choice to prevent oil and process fluid migration.

• For standard installations: The -10-02-00 variant (standard cable, no FluidLoc) may be suitable if fluid ingress is not a concern.

• For system completion: Pair with a 3300 XL Proximitor Sensor and matching 4.0-meter extension cable to form a complete 5.0-meter system.
