Technical Specifications

Mechanical & Environmental Protection

1. Compact Metric Case: With an overall case length of just 30 mm and a standard M10 x 1 thread, this probe is engineered for space-constrained installations. The unit maintains high structural integrity with a nominal weight of 323 grams per meter, ensuring stability in high-vibration environments.

2. Advanced Pressure Sealing: The probe is designed to seal differential pressure between the tip and case using a high-quality Viton® O-ring. To preserve the integrity of this seal, it is critical to avoid exposing the probe to temperatures below -34°C (-30°F), which could lead to premature seal failure.

3. ClickLoc Connectivity: The miniature coaxial ClickLoc connector is designed for ease of use and maximum signal transmission. It is gold-plated and features a locking mechanism that resists the loosening effects of high-frequency machinery vibration.

Installation Guidelines

Mounting & Gap Setting: For radial vibration monitoring, the recommended gap setting is -9 Vdc (approximately 1.27 mm or 50 mils). The maximum thread engagement for this model is 15 mm. Ensure the target surface is properly prepared to stay within the 2 mm linear range for accurate data.

Hazardous Area Wiring: This probe is certified for intrinsically safe applications (Class I, Zone 0) when used with approved zener barriers or galvanic isolators per drawing 141092. It is also rated for non-incendive circuits in Division 2/Zone 2 areas.

Field Wiring: We recommend using a 3-conductor shielded triad cable (0.2 to 1.5 mm²) for field wiring. To minimize high-frequency signal roll-off, keep the distance between the 3300 XL Proximitor Sensor and the monitor under 305 meters (1,000 feet).

Technical FAQs

Q1: What is the benefit of the integrated armor?
A1: The stainless steel armor provides essential mechanical protection for the coaxial cable against abrasion, impact, and fluids common in industrial machinery environments.

Q2: Can this probe handle high humidity?
A2: Yes, the probe is tested to IEC standard 68-2-3, showing less than a 3% change in Average Scale Factor (ASF) even after 56 days in 93% humidity.

Q3: Why is the total length only 0.5 meters?
A3: This length is typically used when the Proximitor Sensor is located very close to the probe, or to reduce excess cable slack in tight internal machine configurations.
