128987-130-00-CN Bently Nevada 3300 XL Probe In Stock

Product Overview

The 128987-130-00-CN is an extended-length Bently Nevada 3300 XL 8 mm Proximity Probe engineered for long-range precision monitoring across large industrial machinery footprints. Equipped with an integrated 13-meter cable, this non-contact eddy current sensor delivers high-accuracy vibration and position measurements without needing intermediate extension cable junctions.

Constructed from chemical-resistant materials compliant with NACE MR0175 standards, the 3300 XL 8 mm Series probe excels in highly corrosive and high-vibration atmospheres. It maintains robust electrical performance when exposed to harsh industrial gases, heavy oil mist, and high ambient thermal stress.

Global PLC Spare HUB's Insight

Long cable runs on large turbo-generator sets often suffer from ground potential loops and high-frequency noise attenuation. In field installations, the 128987-130-00-CN mitigates these signal loss issues through its 1500V AC/DC isolation rating and an 80dB dynamic signal-to-noise ratio. Eliminating inter-cable connectors over the 13-meter span removes a primary point of moisture entry in harsh environments like wastewater aerators and offshore pump decks.

Frequently Asked Questions

Q1: Why choose a 13-meter continuous probe cable instead of using separate extension cables?

A1: Continuous cable runs eliminate intermediate ClickLoc connections, preventing moisture ingress and signal degradation in wet or corrosive process areas.

Q2: Can this sensor handle exposure to aggressive chemical gases in sour gas refining?

A2: Yes, the materials meet NACE MR0175 standards, resisting corrosion from Hydrogen Sulfide (H2S), Ammonia (NH3), and Chlorine (Cl2).

Q3: How low of a frequency can this probe measure on slow-turning machinery?

A3: The extended frequency response reaches down to 0.2 Hz (±1dB), allowing accurate diagnostic monitoring on slow-rotating agitators and mixers.

Q4: Is an additional isolation barrier needed to protect against industrial noise?

A4: The probe features an integrated 1500V AC/DC isolation rating, providing built-in defense against ground potential differences and ambient electrical noise.

Q5: What target shaft speed limit should be observed during machinery monitoring?

A5: Ensure the target surface linear velocity does not exceed 20 m/s (78.7 in/s) to maintain linear output accuracy across the frequency band.
