3300 NSv Probe 330902-00-40-05-01-05 Bently Nevada

Bently Nevada 330902-00-40-05-01-05 NSv Proximity Probe

Product Introduction

The 330902-00-40-05-01-05 belongs to the Bently Nevada 3300 NSv series, a compact family of eddy current proximity transducers for condition monitoring. Specifically, this model is an armored narrow-side-view probe with a 0-inch unthreaded length and a 4-inch overall case length. It features a 1/4-28 UNF thread and a 0.5-metre standard cable with a miniature coaxial ClickLoc connector and protector. Engineers select this probe for non-contact measurement of vibration, radial and axial displacement, and speed signals on small machines. Its stainless steel armor protects the cable from abrasion and mechanical damage. Moreover, the probe operates reliably across a broad temperature span from -52°C to +177°C.

Technical Specifications

The 330902-00-40-05-01-05 carries several options that define its physical and electrical characteristics. First, the unthreaded length is 0 inches, and the overall case length is 4 inches. Next, the total length option "05" indicates a 0.5-metre (20 in) cable. The connector option "01" specifies a miniature coaxial ClickLoc connector with connector protector and standard cable. Additionally, the agency approval option "05" denotes multiple approvals. The probe DC resistance from center conductor to outer conductor measures 4.0 ± 0.5 ohms for the 0.5 m version.

Key electrical and material parameters are listed below:

• Probe Tip Material: Polyphenylene sulfide (PPS)

• Probe Case Material: AISI 304 stainless steel (SST)

• Cable Type: 75 Ω coaxial, FEP insulated

• Connector Torque (Maximum): 0.565 N·m (5 in·lb)

• Minimum Bend Radius: 25.4 mm (1.0 in)

Mechanical and Environmental Parameters

The probe case uses a 1/4-28 UNF thread. Maximum thread engagement length reaches 0.375 inches. For installation torque, the recommended value is 5.1 N·m (45 in·lb), while the maximum rated torque is 7.3 N·m (65 in·lb). Besides, the operating and storage temperature range extends from -52°C to +177°C (-62°F to +351°F). The probe seals differential pressure between the tip and case using a Viton O-ring. However, note that probes are not pressure tested before shipment. Exposing the probe to temperatures below -34°C for a sustained period may cause premature failure of the pressure seal. The probe weighs approximately 14 to 150 g depending on configuration.

Installation Guide

Proper installation ensures measurement accuracy and probe longevity. First, prepare the mounting point with the correct 1/4-28 UNF threaded hole. Next, apply the recommended torque of 5.1 N·m to secure the probe case. Do not exceed the maximum rated torque of 7.3 N·m. Route the armored cable carefully, and observe the minimum bend radius of 25.4 mm. Then, connect the ClickLoc connector to the extension cable or proximitor sensor. Finger-tighten the connector, and avoid exceeding 0.565 N·m. Finally, verify the probe DC resistance at the connector to confirm cable integrity before system commissioning. The stainless steel armor adds mechanical protection but does not change the electrical characteristics.

FAQ

Q1: What is the total cable length of this probe?
A1: The 330902-00-40-05-01-05 includes a 0.5-metre (20 in) cable. This short length suits compact machines with the proximitor mounted nearby.

Q2: Does this probe include cable armor?
A2: Yes. The base model 330902 includes stainless steel armor. This armor protects the cable from abrasion, crushing, and mechanical damage in harsh installations.

Q3: What is the maximum tightening torque for the probe case?
A3: The maximum rated torque is 7.3 N·m (65 in·lb). However, Bently Nevada recommends 5.1 N·m (45 in·lb) for normal installation.

Q4: Does this probe carry agency approval?
A4: Yes. The agency approval option "05" denotes multiple approvals. Confirm that the specific approvals match your site requirements before installation.

Q5: What shipping methods do you offer?
A5: We ship worldwide via Fedex, UPS, and DHL. All orders include tracking and careful packaging for industrial components.
