Product Overview & Key Features

• Manufacturer: Bently Nevada (Baker Hughes) – industry leader in machinery protection.
• Model Number: 330104-01-06-10-02-00 – complete 1‑meter system with armored cable.
• Series: 3300 XL 8 mm Proximity Probes – metric configuration.
• Measurement Principle: Eddy current displacement sensing for non‑contact vibration and position monitoring.
• Linear Range: 2 mm (80 mils) from 0.25 mm to 2.3 mm target gap (–1 to –17 Vdc output).
• Recommended Gap Setting: –9 Vdc ≈ 1.27 mm (50 mils) for optimal radial vibration measurement.
• Probe Tip Material: Polyphenylene sulfide (PPS) – resists chemicals and thermal stress.
• Case Material: AISI 303 / 304 stainless steel with M10 x 1 thread.
• Temperature Range (Standard): –52°C to +177°C (–62°F to +350°F) for the probe tip.
• Extended Temp Option: Tip up to +218°C; cable and connector up to +260°C.
• Magnetic Field Immunity: Negligible output shift up to 300 Gauss (60 Hz) – see detailed gap vs. effect data.

Frequently Asked Questions (FAQ)

• Q: Which Proximitor® sensor works with this 1‑meter probe?
  A: The 330104-01-06-10-02-00 works with both 1‑meter and 5‑meter Proximitor® sensors. Use the matching sensor for optimal scale factor accuracy.
• Q: What is the maximum field wiring distance from Proximitor® to monitor?
  A: You can extend up to 305 meters (1000 feet) using shielded triad cable while maintaining frequency response within specification.
• Q: Does the probe withstand high humidity or washdown environments?
  A: Yes, the 3300 XL 8mm Probe passes 56‑day 93% RH testing with <3% scale factor change. The Viton® O‑ring provides moisture and pressure sealing.
• Q: Is the probe intrinsically safe for hazardous areas?
  A: Yes, when you install it with approved zener barriers or galvanic isolators, it meets Class I, Zone 0 (ia) requirements. See drawing 141092 for wiring.
• Q: What does the suffix code 330104-01-06-10-02-00 fully specify?
  A: It defines 10 mm unthreaded length, 60 mm case length, 1.0 m overall probe length, ClickLoc™ coaxial connector, and no agency approval. Perfect for compact machinery protection.
