Bently Nevada 330104-00-12-10-11-00 3300 XL 8 mm Probe

Overview

The Bently Nevada 330104‑00‑12‑10‑11‑00 is an 8 mm proximity probe with an integral cable, designed for non‑contact measurement of shaft vibration and position in fluid‑film bearing machinery. As part of the 3300 XL transducer family, it delivers stable eddy‑current sensing performance and is widely used in turbines, compressors, pumps, and other critical rotating assets.

Functional Characteristics

This probe features an 8 mm tip with an M10×1 threaded body for precise mechanical alignment. The –12 suffix indicates a 1.2‑meter integral cable, while the –10‑11‑00 configuration defines the probe’s mechanical length, connector type, and system compatibility.

When paired with a matching 3300 XL extension cable and Proximitor sensor, the 330104‑00‑12‑10‑11‑00 provides standard 3300 XL sensitivity (typically 8 mV/μm). The probe maintains excellent linearity across the full API 670‑compliant measurement range, supporting both static and dynamic measurements.

Its construction ensures high immunity to RFI/EMI, enabling installation in fiberglass or non‑metallic conduit without additional shielding. The probe is engineered for long‑term stability across a wide operating temperature range.

FAQ

Q: Does this model include the Proximitor sensor A: No. This model includes the probe with integral cable; the Proximitor sensor is purchased separately.

Q: What does the “–12” suffix indicate A: It specifies a 1.2‑meter integral cable length.

Q: Is the probe interchangeable with other 3300 XL components A: Yes. Probes, extension cables, and Proximitor sensors are fully interchangeable without field calibration.
