Key Parameters 

Core Features & Advantages

• Reverse Mount Design for Space-Constrained Installations: The module's standout feature is its Reverse Mount configuration. Unlike standard probes that thread from the outside, this probe is mounted from the rear side of a bracket or housing, 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 molded PPS plastic tip for chemical and abrasion resistance, an AISI 303/304 stainless steel case for durability, and a Viton O-ring to prevent moisture and dust ingress. The increased diameter of the probe body provides a stronger, more robust casing for harsh industrial environments.

• Complete Interchangeability with Legacy Systems: The 3300 XL 8 mm Reverse Mount Probe is electrically and physically interchangeable with both 5 mm and 8 mm components from the non-XL 3300 series. It also maintains full compatibility with 3300 XL Proximitor Sensors, ensuring seamless integration into existing systems without the need for individual component matching or bench calibration.

• API 670 Compliance for Critical Machinery: The probe fully complies with the American Petroleum Institute's API 670 Standard (4th Edition) for mechanical configuration, linear range, accuracy, and temperature stability, ensuring its suitability for the most demanding oil and gas and power generation applications.

Typical Applications

The 330105-02-12-10-02-00 is widely used for critical rotating machinery monitoring in space-constrained installations:

• Steam Turbines: Radial vibration and axial position monitoring where rear access is available

• Gas Compressors: Shaft displacement measurement in bearing housings with limited mounting space

• Large Industrial Pumps: Vibration monitoring in confined pump casings

• Gearboxes: Non-contact measurement where standard probe orientation is impractical

Frequently Asked Questions (FAQ)

Q1: What does the model number "330105-02-12-10-02-00" indicate?
A: The breakdown is: 330105 = 3300 XL 8 mm Reverse Mount Probe with 3/8-24 UNF thread; -02 = 0.2 in unthreaded length; -12 = 1.2 in (30 mm) case length; -10 = 1.0 meter cable; -02 = Miniature ClickLoc™ coaxial connector (standard); -00 = No agency approvals.

Q2: What is the main advantage of the Reverse Mount design?
A: The reverse mount design allows installation in space-constrained applications where the probe must be mounted from the rear side of a bracket or housing, with the cable exiting opposite the measurement surface. This is ideal for installations with limited rear access that standard front-mount probes cannot accommodate.

Q3: Can this probe be used with legacy 3300 series components?
A: Yes. It is electrically and physically interchangeable with both 5 mm and 8 mm components from the non-XL 3300 series, allowing direct replacement in existing installations.

Q4: What is the recommended installation torque for this probe?
A: The recommended torque is 7.5 N·m (66 in·lbf) and the maximum torque is 22.6 N·m (200 in·lbf) for the 3/8-24 UNF reverse mount thread.

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 -51°C to +177°C (-60°F to +351°F). For temperatures above 177°C, extended temperature range (ETR) probes are required.

Q7: 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.

Q8: What is the linear range and sensitivity of this probe?
A: The linear range is 2.0 mm (80 mils) with a scale factor of 7.87 V/mm (200 mV/mil) ±6.5%.

The 330105-02-12-10-02-00 is part of the 3300 XL 8 mm Reverse Mount Probe family. Below are related models for different configurations:

Choosing the Right Model

• For standard 1.0 m reach applications: The 330105-02-12-10-02-00 is the correct choice for reverse mount installations requiring a 30 mm case and 1.0 m integrated cable.

• For shorter or longer cable runs: Select the -05 (0.5 m) or -90 (9.0 m) cable length options as needed.

• For hazardous area installations: Choose 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.
