Bently Nevada 330901-14-43-05-02-05 Proximity Probe
Product Introduction
The 330901-14-43-05-02-05 comes from the Bently Nevada 3300 NSv family. This proximity probe detects shaft vibration and axial displacement in rotating equipment. Moreover, it supports turbine, compressor, and pump monitoring systems.
Field engineers value this model for its short 0.5 m cable. The 330901-14-43-05-02-05 uses a 1/4-28 UNF thread without armor. In addition, its unthreaded length reaches 1.4 inches, and its case length reaches 4.3 inches. Furthermore, the multiple approvals option widens its use in regulated plants.
Technical Specifications
The probe case is built from AISI304 stainless steel. Its tip uses polyphenylene sulfide (PPS). Additionally, the cable is a 75 Ω coaxial design with fluoroethylene propylene (FEP) insulation.
Main parameters appear below:
Unthreaded Length: 1.4 in (red)
Overall Case Length: 4.3 in (blue)
Total Length: 0.5 meter (20 in) (red)
Connector Type: Miniature coaxial ClickLoc connector
Cable Type: Standard cable
Agency Approval: Multiple Approvals (blue)
Probe DC Resistance: 4.2 ± 0.5 ohms at 1.0 m
The 0.5 m probe length suits tight mounting spaces. Meanwhile, the ClickLoc connector enables quick and stable connections without special tools.
Mechanical and Environmental Parameters
The probe works between -52°C and +177°C. Storage temperature spans the same range. However, sustained exposure below -34°C may harm the pressure seal. Therefore, avoid prolonged cold storage near that threshold.
Pressure sealing depends on a Viton O-ring. Bently Nevada does not pressure test each probe before shipment. Besides, the probe weighs roughly 14 to 150 g depending on length.
Thread engagement limits guide safe 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 change 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, check 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 0.5 m cable away from hot surfaces. Use the ClickLoc connector to link the extension cable. After that, measure the DC resistance from center conductor to outer conductor. A reading near 4.2 ohms indicates a healthy circuit.
Finally, fasten the cable with clamps. Avoid sharp bends and strong pull forces. These steps protect the FEP insulation and extend probe service life.
