1. Product Overview — Bently Nevada 330850‑90‑00

Introduction

The Bently Nevada 330850‑90‑00 is a member of the 3300 XL 25 mm Proximitor sensor family (non‑contact displacement / proximity sensor). Its principal role is to measure radial displacement (gap), vibration, or shaft movement in rotating machinery by converting signals from a proximity probe and extension cable into a usable electrical output.

The “90” in its part number denotes a 9.0‑metre total system length (probe + cable + sensor). The “00” suffix indicates it is a no‑approval model (i.e. without special agency certifications).

Because of its extended length, it is suited for installations where the sensing probe may be located further from the instrumentation panel or where access is constrained.

This model is used in power plants, petrochemical plants, process facilities, rotating equipment diagnostic setups, etc.

2. Technical Specifications — 330850‑90‑00

Below is a consolidated table of known or credible specifications for 330850‑90‑00. Some values are from public listings and inference based on similar models, so for critical engineering use you should confirm via the official datasheet.

Notes / Clarifications:

• The listing from Teknihaus states: “Mounting Option: 9.0 m system length, panel mount, no approvals, shipping weight: 2 kg”

• Other listings confirm the “00” suffix means “no approvals” and that the sensor is panel mount for the “90” version

• Public listings also claim measurement range to 12.7 mm, frequency bandwidth to 10 kHz, pressure rating 10,000 psi, and sensitivity –200 mV/mil

• Notice the probe’s temperature rating is very high (–35 to +177 °C) in some listings, likely indicating a high-temperature probe compatibility.

3. Applications

The 330850‑90‑00 is suitable in scenarios where the sensing probe must be placed further away from the monitoring electronics due to layout constraints. Typical applications include:

• Turbine generator shaft displacement / vibration measurement

• Large motors, compressors, pumps in process plants

• Long extension distances in control rooms or remote panels

• Retrofitting older 7200 / DE proximity systems with modern 3300 XL series

• Vibration analysis, trend monitoring, and protective alarm systems

• Condition monitoring in petrochemical, refining, power generation facilities

Because of its 9 m length, it allows flexibility in panel placement without needing intermediate signal repeaters, which is beneficial in complex installations.

4. Advantages & Key Features

Here are the key benefits and design highlights of the 330850‑90‑00:

• Extended reach: The 9.0 m system length supports installations where the probe is remote from the control instrumentation.

• Non-contact measurement: No physical contact with shaft, avoiding wear and friction effects.

• High dynamic response: Up to 10 kHz bandwidth captures fast vibration events.

• Robust against interference: Designed with good EMI/RFI suppression, suitable for harsh industrial environments.

• Proven compatibility: Fully compatible with the 3300 XL 25 mm family of probes, extension cables, and monitoring modules.

• SpringLoc wiring: Simplifies field wiring and helps maintain strong electrical connections without special tools.

• High-temperature probe compatibility: Some data suggests support of high probe temperatures (up to +177 °C) enabling use in hot zones.

• Flexible mounting: Panel-mount proximitor module allows easier integration into existing cabinets.

• Reliable brand lineage: Backed by a strong track record of reliability in rotating machinery monitoring systems.
