Bently Nevada 22811-00-25-05-02 Proximity Sensor / Probe

FAQ

Q1: What is Bently Nevada 22811-00-25-05-02?
A: It is a Bently Nevada proximity sensor/probe used for non-contact monitoring of rotating machinery. Supplier records specifically identify this exact part number as a proximity sensor.

Q2: Which product series does 22811-00-25-05-02 belong to?
A: It belongs to the Bently Nevada 7200 Series proximity transducer system, which is used for machinery vibration and displacement monitoring. The 7200 family includes probes and extension cables with different mechanical and cable configurations.

Q3: What is the probe diameter?
A: The 22811 family is associated with an 8 mm proximity-probe configuration. The exact mechanical drawing should be checked before installation where mounting clearance is critical.

Q4: What is the cable length of 22811-00-25-05-02?
A: This configuration is associated with a 5 m cable. The cable length is an important part of the complete part-number configuration.

Q5: What sensing principle does this sensor use?
A: The 7200 proximity system uses non-contact eddy-current sensing to detect changes in the distance between the probe tip and a conductive rotating shaft or target.

Q6: What is the typical measurement range?
A: The 7200 system is commonly associated with a linear measurement range of approximately 80 mils (2 mm) and a nominal sensitivity of about 200 mV/mil (7.87 mV/µm). Exact performance depends on the complete transducer configuration.

Q7: What are the dimensions and weight of 22811-00-25-05-02?
A: The probe diameter is approximately 8 mm, while the overall length depends on the specific mechanical configuration. A practical reference weight is approximately 0.20–0.30 kg. Actual packed shipping weight should be confirmed separately.

Q8: Is 22811-00-25-05-02 still available?
A: The part is listed as a legacy/discontinued Bently Nevada component, but surplus and refurbished units are still available through industrial automation suppliers. Radwell, for example, identifies the exact part number as discontinued by the manufacturer.
