Description
Compact Armored Sensor for Smaller Machinery
The Bently Nevada 330904-00-12-05-02-00 is a new-generation 8mm proximity probe. It features a stainless steel armored case and M8 metric thread. This sensor is perfect for monitoring vibration on pumps, motors, and small turbines where space is limited.
Key Product Advantages
- Small & Strong: M8x1 thread and armored body fit tight spaces while resisting damage.
- Improved Chemical Resistance: Better than older 3300 RAM probes for harsh process environments.
- Easy Upgrade: Directly interchangeable with previous 3300 RAM probes and cables.
- Wide Frequency Response: 0 to 10 kHz range for capturing detailed vibration data.
- Global Stock: New & original, shipped in factory packaging with full 12-month warranty.

Expert FAQ
Compatibility & Performance
- Can I use this to replace my old 3300 RAM probe?
- Yes. The 330904-00-12-05-02-00 is mechanically and electrically interchangeable with 3300 RAM probes. It is a direct upgrade with better chemical resistance.
- Why is the recommended gap 1.0 mm instead of 1.27 mm?
- The 3300 NSv series has a shorter linear range (1.5 mm vs 2.0 mm). Gapping at 1.0 mm (40 mils) centers the measurement in this optimal range for best accuracy.
Installation & Use
- How much should I tighten this M8 probe?
- Use a torque wrench. Tighten to the recommended 5.1 N•m (45 in-lb). Do not exceed 7.3 N•m (65 in-lb). Do not engage more than 12mm of thread.
- What size target does this probe need?
- For accurate radial vibration, the target should be at least 13 mm (0.5 in) in diameter. For smaller shafts, expect some change in sensitivity.
Ordering & Delivery
- Do you have stock for immediate shipment?
- Yes, the 330904-00-12-05-02-00 is typically in stock. We can arrange fast dispatch with FedEx, UPS, or DHL upon order confirmation.
