Quick Detail

Description

The 330105-02-12-05-12-05 3300 XL 8 mm Reverse Mount Probes are high-performance eddy current proximity sensors specifically engineered for accurate, stable, and long-term non-contact measurement in demanding industrial condition monitoring systems. Designed with a reverse mount configuration, these probes enable precise installation from the opposite side of the mounting surface, making them an optimal solution for applications where axial space is limited or traditional forward-mount probes cannot be installed.

The 3300 XL 8 mm Reverse Mount Probes operate on the proven eddy current measurement principle, where the output voltage is directly proportional to the distance between the probe tip and a conductive target surface. This linear voltage-to-gap relationship allows the probe to measure both static parameters, such as shaft position or axial displacement, and dynamic parameters, including vibration amplitude and transient motion. As a result, the probe supports comprehensive monitoring of rotating machinery health and operational stability.

Engineered to meet rigorous industrial standards, the 3300 XL 8 mm Reverse Mount Probes deliver consistent performance across a wide temperature range from -52°C to +177°C, ensuring reliable data acquisition in extreme environments. The probe case is manufactured from AISI 303/304 stainless steel, providing excellent resistance to corrosion, mechanical stress, and industrial contaminants, while the PPS probe tip enhances durability and dimensional stability during prolonged exposure to heat and vibration.

Applications

The 330105-02-12-05-02-00 3300 XL 8 mm Reverse Mount Probes are engineered for precision measurement and equipment condition monitoring across diverse industrial environments, with parameters tailored to critical use cases. Its compact 1.2x1.1x64cm dimension, 0.04kg weight, 0mm minimum unthreaded length, and 60mm case length make it ideal for space-constrained installations—such as narrow cavities in rotating machinery, fluid-film bearing assemblies, and compact precision instruments where traditional probes cannot deploy.​With an operating temperature range of -52°C to +177°C (-62°F to +341°F), AISI 303/304 stainless steel case, and PPS probe tip, the probe excels in extreme and harsh environments. Key applications include power generation (gas/steam turbines, reciprocating engines), petrochemical refineries (centrifugal pumps, compressors), aerospace ground support, marine propulsion, and chemical processing equipment.​Optimized for accuracy, the probe’s 2 mm (80 mils) linear range enables reliable static position (e.g., rotor axial displacement) and dynamic vibration measurement, supporting predictive maintenance. Its 50 Ω output resistance, sensitivity, and -17.5 to -26 Vdc power requirement ensure stable integration with standard industrial systems. The 0.5m (1.6ft) cable with Miniature ClickLoc coaxial connector offers flexible, secure installation for restricted routing or frequent maintenance scenarios.​Additionally, the probe serves as a critical component in Keyphasor reference and speed measurement for rotating equipment. Compatible with 3300 series components (including backward compatibility with non-XL models) and API 670 compliant, it is a versatile upgrade for existing systems in automotive, steel, pharmaceutical, and oil/gas industries (pipeline pumps, turbomachinery).​In summary, the 3300 XL 8 mm Reverse Mount Probes integrate compact design, extreme resilience, and precision to address space-constrained, harsh-environment, and high-precision industrial needs—delivering consistent performance across power generation, petrochemicals, aerospace, and manufacturing to optimize equipment health and operational efficiency.

Specifications

Competitive Advantage

1. Ultra-Compact Design Ideal for Space-Limited Installations​

With a sleek footprint of 1.2x1.1x64cm and an ultra-light weight of just 0.04kg, the 3300 XL 8 mm Reverse Mount Probes excel in space-constrained settings. Its minimal 0mm unthreaded length and 60mm (2.4 inches) total case length allow for seamless integration into narrow cavities, tight fluid-film bearing assemblies, and compact precision instruments—spaces where conventional probes often cannot fit. This design eliminates the need to modify equipment to accommodate measurement tools, opening up broader application possibilities in industrial environments with limited clearance.​

2. Exceptional Environmental Resilience for Harsh Operating Conditions​

Engineered to thrive in extreme environments, the probe delivers reliable performance across a wide temperature spectrum from -52°C to +177°C (-62°F to +341°F), making it suitable for both freezing and high-heat industrial scenarios. Its durable build—featuring an AISI 303 or 304 stainless steel (SST) case that resists corrosion and mechanical wear, paired with a polyphenylene sulfide (PPS) probe tip for added toughness—ensures long-term stability in abrasive, chemical-exposed, or high-pressure settings such as petrochemical refineries and marine propulsion systems. Unlike standard probes that tend to deteriorate under harsh conditions, this model maintains consistent measurement accuracy and structural integrity, reducing the need for frequent replacements and lowering maintenance expenses.​

3. High Measurement Precision & Reliable Signal Transmission​

Tailored for critical measurement tasks, the 3300 XL 8 mm Reverse Mount Probes offer superior precision thanks to a 2 mm (80 mils) linear range, enabling accurate detection of both static position (e.g., rotor axial displacement) and dynamic vibration data—critical for effective predictive maintenance programs. Key electrical specs, including a 50 Ω output resistance and supply sensitivity of fewer than 2 mV of output change per volt of input variation, guarantee steady, low-noise signal delivery. The probe’s power requirement of -17.5 Vdc to -26 Vdc aligns with standard industrial power systems, eliminating the need for specialized power sources and ensuring smooth integration with existing monitoring setups without signal interference or performance drops.
