        Features:

        • Bridge Between the Probe Tip and the 7200 Proximitor® Signal Conditioning Module
        • Integrates Noncontacting Gap-to-Voltage Transduction with Harsh Environment Durability
        • Functions Together with the 7200 Series and Standard 3300/9000 Monitoring Systems
        The Bently Nevada 21504-00-12-05-02 operates as the 8 mm Standard Mount Probe in a 7200 Proximity Transducer System, providing accurate displacement measurement for all rotating and reciprocating machinery monitoring applications. It continuously generates a gap-dependent voltage signal (200 mV/mil scale factor, 80 mils linear range) from the target surface and transmits this signal through its integral coaxial cable to support real-time shaft position and vibration analysis. Robust Cable LoC™ junction construction is standard with the 21504-00-12-05-02, however using the proper 3/8-24 threaded mounting configuration will ensure secure probe retention during installation and operation in demanding industrial environments. The 21504-00-12-05-02 has made improvements in several areas over previous probe designs in addition to incorporating polyphenylene sulfide (PPS) construction capable of withstanding unusually harsh, wet and/or chemical conditions.

        The 21504-00-12-05-02 provides essential sensing functions common to the entire transducer system, and is a critical component of the measurement path, directly affecting the accurate, reliable operation of the overall machinery protection system. One 21504-00-12-05-02 probe is required per measurement point depending on the desired monitoring configuration. The 21504-00-12-05-02 occupies minimal mounting space with its 1.2-inch overall case length and 0.0-inch unthreaded length, and is always positioned with its miniature male coaxial connector oriented for proper extension cable interface.

        For complete transducer system applications, the 7200 System requires a matching extension cable and Proximitor® module connected to the 21504-00-12-05-02 probe. In addition to standard single-probe operation, the system configuration also performs continuous dynamic measurement. The 7200 transducer system executes signal conditioning using the internal circuitry specified in the Proximitor® options. Using this method, the measurement system continually monitors the gap between the 21504-00-12-05-02 probe tip and the observed target. If the system detects that the shaft position or vibration amplitude exceeds configured alarm thresholds (outside acceptable displacement/tolerance levels), it will automatically generate proportional voltage output and trigger appropriate machinery protection responses.

        The 21504-00-12-05-02 Bently Nevada 8 mm Standard Mount 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 21504-00-12-05-02 is a high-precision 8 mm Standard Mount Probe belonging to the 7200 Proximity Transducer System series. This non-contacting, gap-to-voltage transducer system is specifically designed to measure both static and dynamic distances between the probe tip and a target surface. This 21504-00-12-05-02 model features an 8 mm diameter probe tip, standard 3/8-24 configuration threads, and a total length of 0.5 meters (20 inches). It is engineered with a 1.2-inch overall case length and zero unthreaded length, terminating in a miniature male coaxial connector without lead armor.

        The 21504-00-12-05-02 is purpose-built to handle the critical challenge of monitoring shaft position and vibration in high-speed rotating and reciprocating machinery. It effectively solves the problem of maintaining mechanical integrity in equipment such as gas and steam turbines, compressors, and electric motors by providing accurate displacement measurements. By offering a linear measuring range of 80 mils (2 mm) with a scale factor of 200 mV/mil, the 21504-00-12-05-02 allows operators to detect minute mechanical shifts and vibrations before they lead to catastrophic equipment failure, ensuring compliance with API 670 requirements.

        Durability and reliability in harsh industrial environments are central to the design of the 21504-00-12-05-02. Constructed from polyphenylene sulfide (PPS), a high-performance plastic, the probe is capable of withstanding unusually wet or chemical-heavy environments. Furthermore, this 21504-00-12-05-02 unit incorporates Bently Nevada’s Cable LoC™ feature, which provides an exceptionally strong junction between the coaxial cable and the probe tip. This design advancement solves the common issue of cable detachment or damage during installation and operation, making the 21504-00-12-05-02 a robust solution for long-term machine health monitoring in confined or demanding spaces.
