This transducer is optimized to capture high-frequency impact signals, making it an essential tool for identifying bearing wear and fluid cavitation. A key design advantage is its ultra-lightweight construction, weighing only \u003cstrong\u003e58 g (2.0 oz)\u003c\/strong\u003e. This low mass ensures the sensor does not dampen the high-frequency vibrations of the machine casing, providing the most accurate diagnostic data possible. This model features a 3\/8-24 to 1\/2-20 UNF hex plate stud for high-integrity mechanical mounting.\n\u003c\/p\u003e\n\n\u003ch2\u003eAdvanced Diagnostics \u0026amp; Enveloping\u003c\/h2\u003e\n\u003cp\u003e\n  Specifically built for the Trendmaster Pro platform, the \u003cstrong\u003e200157-03-05\u003c\/strong\u003e delivers high-fidelity acceleration data across a frequency spectrum of 10 Hz to 10,000 Hz. With a mounted resonant frequency greater than 20 kHz, it excels at capturing the rapid \"stress waves\" emitted by failing mechanical components. Despite its compact \u003cstrong\u003e58g\u003c\/strong\u003e frame, it maintains a sensitivity of 10.2 mV\/(m\/s²) (100 mV\/g) and an amplitude linearity of ±2%. This ensures that your maintenance team receives consistent, repeatable data for trend analysis and machinery protection.\n\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; font-family: Arial, sans-serif;\"\u003e\n  \u003ctbody\u003e\n    \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6; width: 35%;\"\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003eBently Nevada (Made in U.S.A.)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e200157-03-05\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e58 g (2.0 oz), typical\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e\u003cstrong\u003eMounting Option\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e03 (1\/2-20 UNF Hex Plate Stud)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e\u003cstrong\u003eApprovals\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e05 (Multiple: CSA, ATEX, IECEx)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e\u003cstrong\u003eHousing Material\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 12px; border: 1px solid #dee2e6;\"\u003e316L Stainless Steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eMechanical Integrity \u0026amp; Environmental Limits\u003c\/h2\u003e\n\u003cp\u003e\n  The \u003cstrong\u003eBently Nevada 200157-03-05\u003c\/strong\u003e is built to endure the harshest industrial conditions. The \u003cstrong\u003e58g\u003c\/strong\u003e body is encased in 316L stainless steel and is hermetically sealed to a maximum leak rate of 5x10⁻⁸ atm·cc\/s. It is rated for 100% condensing humidity and operates reliably in temperatures from -40°C to +105°C. Its robust mechanical design allows for an axial shock limit of up to 49,050 m\/s² peak (5000 g), making it ideal for permanent installation on high-impact machinery in the power, oil, and gas sectors.\n\u003c\/p\u003e\n\n\u003ch2\u003eInstallation \u0026amp; Electrical Performance\u003c\/h2\u003e\n\u003cp\u003e\n  The \u003cstrong\u003e200157-03-05\u003c\/strong\u003e operates on an excitation voltage of 4.7 to 5.5 VDC with a quiescent current of less than 800 µA. For optimal high-frequency response, the sensor should be installed with a torque between 2.7 and 6.8 N·m. Because the unit is exceptionally light (\u003cstrong\u003e58 grams\u003c\/strong\u003e), it can be mounted in constrained spaces where larger sensors would face physical or mass-loading limitations. The use of a shear-geometry ceramic sensing element effectively rejects base strain and thermal transients, ensuring that only the relevant vibration signal is processed.\n\u003c\/p\u003e\n\n\u003ch2\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\n  Q1: What is the primary benefit of the 58g weight in the 200157-03-05?\u003cbr\u003e\n  A1: The 58g weight minimizes \"mass loading,\" ensuring the sensor does not alter the vibration characteristics of the machinery surface, which is critical for accurate high-frequency enveloping.\n\u003c\/p\u003e\n\u003cp\u003e\n  Q2: Does the Bently Nevada 200157-03-05 require a specific cable?\u003cbr\u003e\n  A2: It is designed to work within the Trendmaster Pro ecosystem; for optimal performance and minimal signal loss, high-quality shielded cabling is recommended.\n\u003c\/p\u003e\n\u003cp\u003e\n  Q3: Is the 1\/2-20 UNF stud interchangeable?\u003cbr\u003e\n  A3: The \"03\" option specifies this particular stud size.
