Bently Nevada 3300 NSv Probe 330901-04-35-50-01-00

Bently Nevada 330901-04-35-50-01-00 Proximity Probe

Product Introduction

The 330901-04-35-50-01-00 belongs to the Bently Nevada 3300 NSv series. This proximity probe measures shaft vibration and axial position in rotating machinery. Moreover, it delivers reliable signals for turbine, compressor, and motor monitoring systems.

Engineers often choose this probe for its compact case and flexible cable. The model 330901-04-35-50-01-00 uses a 1/4-28 UNF thread without armor. In addition, its unthreaded length is 0.4 inches, and its overall case length is 3.5 inches.

Technical Specifications

The probe case uses AISI304 stainless steel. Its tip is made of polyphenylene sulfide (PPS). Furthermore, the cable is a 75 Ω coaxial type with fluoroethylene propylene (FEP) insulation.

Key parameters appear below:

• Unthreaded Length: 0.4 in (red)

• Overall Case Length: 3.5 in (blue)

• Total Length: 5.0 meters (16.4 feet) (red)

• Connector Type: Miniature coaxial ClickLoc connector with protector

• Cable Type: Standard cable

• Agency Approval: Not required

• Probe DC Resistance: 5.3 ± 0.7 ohms (blue)

The 5.0 m probe length gives a nominal resistance of 5.3 ohms. This value helps technicians verify cable integrity during installation. Meanwhile, the ClickLoc connector allows fast and secure mating.

Mechanical and Environmental Parameters

The probe operates between -52°C and +177°C. Storage temperature covers the same range. However, sustained exposure below -34°C may damage the pressure seal. Therefore, avoid long-term cold storage near that limit.

Pressure sealing relies on a Viton O-ring. Bently Nevada does not pressure test each probe before shipment. Besides, the probe weighs approximately 14 to 150 g depending on length.

Thread engagement limits matter for mounting. For a 3/8-24 case, the maximum thread engagement is 0.563 in. The recommended torque for 3/8-24 or M10X1 cases is 11.3 N•m (100 in•lb). For the first three threads, the recommended torque is 7.5 N•m (66 in•lb).

Temperature classification for EPL Ga and Gc:

• T1: -55°C to +232°C

• T2: -55°C to +177°C

• T3: -55°C to +120°C

• T4: -55°C to +80°C

• T5: -55°C to +40°C

For EPL Dc, the T-class values shift with ambient temperature. For instance, T280°C applies at Ta -55°C to +232°C. Similarly, T90°C applies at Ta -55°C to +40°C.

Installation Guide

First, verify the probe thread and case length against the machine drawing. Next, insert the probe into the mounting hole. Then, tighten it to the recommended torque. Do not exceed the maximum thread engagement.

Route the 5.0 m cable away from high-temperature sources. Use the ClickLoc connector to join the extension cable. After that, check the DC resistance from center conductor to outer conductor. A reading near 5.3 ohms indicates a healthy circuit.

Finally, secure the cable with clamps. Avoid sharp bends and tight pull forces. These steps protect the FEP insulation and extend probe life.
