Technical Specifications

Mechanical Design & Operational Benefits

1. Ultra-Rugged 8mm Construction: This probe features a thick PPS plastic encapsulation for the internal coil, providing significantly higher physical robustness than standard 5mm probes. The 1.5-inch stainless steel housing is fully threaded, allowing for versatile installation depth in standard machine ports. The unit is optimized for vibration damping with a weight profile of 323 g/m.

2. Advanced Connectivity: Equipped with the gold-plated ClickLoc miniature coaxial connector, this probe ensures a secure, vibration-proof electrical path. The CableLoc design provides 75% more pull strength than previous generations, preventing accidental disconnection during maintenance or high-vibration operation.

3. Environmental Resilience: The probe utilizes a Viton® O-ring to provide a hermetic seal against differential pressure (up to 5 bar static pressure). Furthermore, the PPS tip material and FEP cable insulation allow for continuous operation in environments with extreme temperatures and 93% relative humidity with minimal signal variation.

Installation Guidelines

Gap Calibration: The recommended installation gap is 1.27 mm (50 mils), typically resulting in a -9 Vdc output. This centers the sensor within its 80 mil linear range. Performance is optimized when using an AISI 4140 steel target.

Torque Limits: For 3/8-24 UNF threaded cases, the recommended installation torque is 11.3 N•m (100 in•lb). Do not exceed the maximum rated torque of 33.9 N•m to ensure the integrity of the pressure seal and the PPS tip.

Signal Integrity: To maintain high-frequency accuracy (0.5 Hz to 10 kHz), ensure the total field wiring distance between the Proximitor Sensor and the monitor does not exceed 305 meters (1,000 feet) using 3-conductor shielded triad cable.

Technical FAQs

Q: Is this probe compatible with the 3300 XL Proximitor Sensor?
A: Yes, it is the standard probe for the 3300 XL 8 mm system and offers full interchangeability with standard 3300 XL extension cables.

Q: What is the benefit of the 8mm tip over a 5mm tip?
A: The 8mm probe has a thicker encapsulation and a larger diameter, making it much more rugged and resistant to physical abuse during installation or operation.

Q: Can I use this probe in applications with oil leakage concerns?
A: This model uses a standard cable. For applications where oil might leak through the cable interior, we recommend the FluidLoc cable option, which is rated to prevent leakage up to 15 psi.
