Key Parameters 

Core Features & Advantages

• FluidLoc Cable for Fluid Ingress Protection: The module’s standout feature is its FluidLoc cable option (Code 11), 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.

• Armored Construction for Mechanical Protection: The 330104 base model includes stainless steel armor over the probe case, providing enhanced mechanical protection against abrasion, impact, and accidental crushing. This is essential in high-vibration environments such as compressor skids and reciprocating machinery.

• Metric M10 x 1 Thread for Global Compatibility: The M10 x 1 metric thread is common in machinery designed or manufactured outside North America, making this probe suitable for a wide range of international equipment. The maximum thread engagement is 15 mm.

• Complete System Interchangeability: The 3300 XL system supports complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need for individual matching or bench calibration. This probe is backward-compatible with non-XL 3300 series 5 mm and 8 mm transducer components.

Typical Applications

The 330104-00-12-10-11-00 is widely used for critical rotating machinery monitoring in demanding industrial applications:

• Turbine and Compressor Shaft Vibration Monitoring: Captures dynamic vibration and axial position of fluid-film bearings in steam and gas turbines, and centrifugal compressors.

• Fluid-Tight Applications: Ideal for machinery where keeping process fluids or bearing oil contained within the housing is critical (utilizing FluidLoc technology).

• Rotor Axial Position Measurement: Precise thrust position monitoring on critical rotating assets.

• Critical Rotating Machinery Protection: Suitable for petrochemical plants, refineries, and power generation facilities.

Frequently Asked Questions (FAQ)

Q1: What does the model number “330104-00-12-10-11-00” indicate?
A: The breakdown is: 330104 = 3300 XL 8 mm Probe with M10 x 1 metric thread and armor; -00 = 0 mm unthreaded length; -12 = 120 mm case length; -10 = 1.0 meter cable; -11 = Miniature ClickLoc connector with connector protector and FluidLoc cable; -00 = No agency approvals.

Q2: What is the advantage 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: Can this 1.0 meter probe be used with a 5.0 meter extension cable?
A: Yes, provided the total electrical length of the probe plus the extension cable equals the electrical length of the Proximitor sensor. For example, a 1.0 m probe with a 4.0 m extension cable would form a 5.0 m system when paired with a 5 m Proximitor.

Q4: What is the recommended installation gap for this probe?
A: The recommended gap is -9 Vdc, which corresponds to approximately 1.27 mm (50 mils). A healthy system should read between -9 V and -12 V DC at the Proximitor sensor output.

Q5: 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).

Q6: What is the operating temperature range?
A: The probe operates from -52°C to +177°C (-62°F to +351°F). For temperatures above 177°C, extended temperature range (ETR) probes are required.

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.

Q8: Is this probe compatible with all 3300 XL monitoring modules?
A: Yes. It integrates seamlessly with standard 3300 XL monitoring modules and Proximitor Sensors. The 3300 XL system supports complete interchangeability of probes, extension cables, and Proximitor Sensors without individual matching or bench calibration.

Choosing the Right Model

• For fluid-tight applications: The 330104-00-12-10-11-00 with FluidLoc cable is the correct choice to prevent oil and process fluid migration.

• For hazardous area installations: Choose a variant with the -05 suffix for CSA, ATEX, and IECEx certifications.

• For system completion: Pair with a 3300 XL Proximitor Sensor and matching extension cable (if required) to form a complete transducer system.
