The 330901-22-12-10-02-00 belongs to the Bently Nevada 3300 NSv series, a compact family of eddy current proximity transducers for condition monitoring. Specifically, this model is a narrow-side-view probe with a 2.2-inch unthreaded length and a 1.2-inch overall case length. It features a 1/4-28 UNF thread and a 1.0-metre standard cable with a miniature coaxial ClickLoc connector. Engineers select this probe for non-contact measurement of vibration, radial and axial displacement, and speed signals on small machines. Its slim case fits confined mounting spaces where standard probes cannot reach. Moreover, the probe operates reliably across a broad temperature span from -52°C to +177°C.
The 330901-22-12-10-02-00 carries several options that define its physical and electrical characteristics. First, the unthreaded length is 2.2 inches, and the overall case length is 1.2 inches. Next, the total length option "10" indicates a 1.0-metre (39 in) cable. The connector option "02" specifies a miniature coaxial ClickLoc connector with standard cable. Additionally, the agency approval option "00" means no agency approval is required. The probe DC resistance from center conductor to outer conductor measures 4.2 ± 0.5 ohms for the 1.0 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)
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.
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 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. Because this model carries no agency approval option, confirm local site requirements before installation.

Q1: What is the total cable length of this probe?
A1: The 330901-22-12-10-02-00 includes a 1.0-metre (39 in) cable. This length suits compact machines with the proximitor mounted nearby.
Q2: Does this probe carry agency approval?
A2: No. The agency approval option "00" means no approval is required or included. Check your site regulations before use in hazardous areas.
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 come with armor?
A4: No. The base model 330901 without an armor suffix indicates an unarmored probe with a standard cable.
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.
