The Bently Nevada 330101-00-63-20-12-05 is a component of the 3300 XL 8 mm Proximity Transducer System. This system is designed for precise non-contact measurements of vibration and position in rotating machinery. It includes a probe, extension cable, and Proximitor sensor. The probe translates shaft movement into an electrical signal proportional to the distance to the observed surface.

Technical Specifications

FAQ

Q1: What is the typical application of this proximity probe?

A1: It’s used for vibration and position measurements in rotating machinery, especially fluid-film bearing equipment.

Q2: Is this product compliant with API 670?

A2: Yes, the 3300 XL 8 mm system meets API 670 requirements for range, accuracy, and temperature stability.

Q3: Can I mix XL and non-XL 3300 components?

A3: Yes, but system performance will be limited to that of the non-XL components.

Q4: What is the minimum shaft diameter recommended?

A4: The probe is optimized for shafts with a diameter of 76.2 mm (3 in) or larger.

Q5: How is the probe mounted?

A5: It uses a 3/8-24 UNF threaded stainless steel case and mounts into tapped holes or brackets.

Q6: What does the “FluidLoc” cable option do?

A6: It prevents oil or fluid migration along the cable into enclosures or sensor housings.

Q7: Is it resistant to EMI/RFI interference?

A7: Yes, the system offers high immunity, enabling installation without shielded conduit.

Q8: Can the system operate at high temperatures?

A8: Yes, with the ETR (Extended Temperature Range) version, it handles up to +260°C.

Q9: What kind of output does the sensor provide?

A9: It provides a voltage output proportional to the probe-target distance.

Q10: Is calibration required if components are swapped?

A10: No, 3300 XL components are fully interchangeable without the need for recalibration.
