Bently Nevada 3300 XL 8 mm Proximity Probe – 330103-02-10-05-01-05

Author: Ubest Automation. The 3300 XL 8 mm Proximity Probes deliver precise non-contact displacement measurements. We present the variant 330103-02-10-05-01-05 — a rugged metric probe engineered for extreme conditions. Bently Nevada designs this sensor for radial vibration and position monitoring in critical machinery.

• Brand: Bently Nevada
• Product type: 3300 XL 8 mm proximity probe, metric

Key technical specifications

• Linear range: 2 mm (80 mils) from 0.25 to 2.3 mm (–1 to –17 Vdc). Recommended radial vibration gap: –9 Vdc (≈1.27 mm / 50 mils).
• Probe DC resistance (RPROBE): 7.45 ± 0.50 Ω (0.5 m length, centre to outer conductor).
• Temperature range (standard probe): operate/storage –52°C to +177°C (–62°F to +350°F). Extended tip version available up to 218°C.
• Relative humidity: less than 3 % ASF change after 56 days at 93 % RH (IEC 68‑2‑3).
• Materials: probe tip = polyphenylene sulfide (PPS); case = AISI 303/304 stainless steel; sealing = Viton® O‑ring.
• Thread & engagement: M10 x 1, maximum thread engagement 15 mm.
• Weight: 323 g/m (11.4 oz per metre).

Installation & field wiring

• Use 3‑conductor shielded triad cable, 0.2 to 1.5 mm² (16–24 AWG), tinned leads.
• Maximum extension cable length: 305 metres (1000 feet) between probe and 3300 XL Proximitor Sensor.
• For signal roll‑off at high frequencies with long cables, refer to frequency response graphs (figures 10 & 12 in manual).
• The probe seals differential pressure with a Viton O‑ring. Not pressure‑tested before shipment – contact custom design if testing is required.
• Probe tip material PPS, case stainless steel – robust against harsh environments.

Environmental & hazardous area approvals

• ATEX / IECEx / CSA: 330103-02-10-05-01-05 carries approval option 05.
• Intrinsically safe when installed with zener barriers (drawing 141092) or galvanic isolators:
  • Class I, Zone 0 AEx/Ex ia IIC T5…T1 Ga; Class I, II, III Div.1 Groups A–G.
• Non‑incendive / ec installation per drawing 140979:
  • Class I, Zone 2 AEx/Ex nA IIC T5…T1 Gc; Class I Div.2 Groups A–D; Ex ec IIC T5…T1 Gc.
• Temperature classification (probe only):
  • EPL Ga/Gc: T5 @ –55 to +40°C, T4 @ –55 to +80°C, T3 @ –55 to +120°C, T2 @ –55 to +177°C, T1 @ –55 to +232°C.
  • EPL Dc: T90°C @ Ta –55 to +40°C … T280°C @ Ta –55 to +232°C (detailed schedule in manual).
• Exposure below –34°C may cause premature pressure‑seal failure – consider this during winter installation.

Frequently asked questions
