        Features:

        • Integrated Signal Processing Design Eliminates Need for External Proximitor
        • Large Diameter Probe Supports Extended Displacement Measurement Range
        • Stainless Steel Armored Cable Enhances Durability in Harsh Environments
        The Bently Nevada 102244-22-50-01 represents a legacy solution for proximity-based displacement measurement in large rotating machinery. Designed with a 25 mm probe diameter, it is capable of monitoring significant shaft movements that smaller probes cannot accurately capture. Its application is particularly relevant in systems where differential expansion must be continuously observed to prevent mechanical failure.

        One of the most distinctive aspects of the Bently Nevada 102244-22-50-01 is its integrated electronics. By embedding the Proximitor within the probe body, the system simplifies wiring and reduces external component requirements. This design was advantageous in earlier installations, although it contrasts with the modular approach used in modern systems.

        Despite being obsolete, the Bently Nevada 102244-22-50-01 remains important in maintaining legacy installations. Its rugged construction, including stainless steel armor and compatibility with AISI 4140 materials, ensures reliable performance in demanding environments. When upgrading, users must consider the architectural shift to the 3300 XL system, which separates probe, cable, and signal processing functions for improved flexibility and maintainability.

        The 102244-22-50-01 Bently Nevada Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The Bently Nevada 102244-22-50-01 is a 25 mm proximity probe developed for earlier large-scale machinery monitoring systems, particularly within the 7200 series. It is engineered to measure significant shaft movements such as differential expansion and axial displacement in heavy rotating equipment. With a probe diameter of 25 mm (1.0 inch), it is well-suited for applications requiring extended measurement range and mechanical robustness.

        A defining characteristic of the Bently Nevada 102244-22-50-01 is its built-in Proximitor functionality. Unlike modern proximity systems that separate the probe, extension cable, and preamplifier, this model integrates signal processing directly within the probe assembly. This design allows it to output a conditioned voltage signal without requiring additional external modules, simplifying installation in legacy systems.

        The probe operates with a rating of -24.5 VDC at 20 mA and provides a scale factor of 0.8 V/mm (20 mV/mil), ensuring consistent signal interpretation for displacement monitoring. It is designed to observe materials such as AISI 4140, which are commonly used in industrial rotating machinery. The Bently Nevada 102244-22-50-01 also features a stainless steel armored cable, indicated by the -01 suffix, offering enhanced protection against mechanical stress and harsh operating conditions.

        In terms of mechanical construction, the probe typically uses a smooth cylindrical or threaded housing of approximately 1.06 inches, depending on mounting configuration. This allows flexible installation across various machine designs. However, the Bently Nevada 102244-22-50-01 is now classified as obsolete (Phase 5), and users are encouraged to transition to newer systems such as the 3300 XL 25 mm probe series.

        When replacing the Bently Nevada 102244-22-50-01, it is important to note that modern alternatives like the 330851 probe require a split architecture. Unlike the integrated design of the Bently Nevada 102244-22-50-01, the new system requires a 330854 extension cable and a 330850 Proximitor. This difference means direct substitution is not possible without system redesign, but the newer solution offers improved flexibility and long-term support.
