The Bently Nevada 45357-01 is a charge-coupled piezoelectric accelerometer designed for reliable vibration monitoring on rotating machinery. This 50 pC/g sensor provides accurate vibration data when paired with compatible interface modules such as the 86517 series. Its robust construction features a piezoelectric crystal isolated from the case, delivering a differential output for improved noise immunity. The 45357-01 carries CSA certification for use in Class I, Divisions 1 and 2 hazardous areas, making it suitable for demanding industrial environments. This product is brand new and arrives in its original factory-sealed packaging.
The 45357-01 accelerometer delivers consistent performance for vibration monitoring applications. Its key parameters are detailed below.
Sensitivity: 50 pC/g ±5%.
Typical Capacitance: 1000 pF (pole-to-pole).
Mounting: Four holes at the corners of a square with 1.188 inch (30.18 mm) sides; suitable for 0.25 inch (6 mm) bolts.
Connector: MS3100R-10SL-4P receptacle.
Weight: 15 ounces (425 grams) nominal.
Output Type: Differential, isolated from the accelerometer case.
Furthermore, the 45357-01 uses a piezoelectric sensing element that generates a charge output proportional to acceleration. The accelerometer's sensitive axis is clearly marked with an arrow on the side of the housing. For proper operation, you must orient this sensitive axis 90 degrees to the rotor axis.
Correct mounting is essential for accurate vibration measurement with the Bently Nevada 45357-01. Follow these recommendations for optimal performance.
Mounting Surface: Ensure the mounting surface is flat, smooth, and rigid. The mounting structure must have no mechanical resonances within your frequency range of interest.
Hole Preparation: Drill four holes for 0.25 inch (6 mm) bolts at the corners of a 1.188 inch (30.18 mm) square. The holes must be perpendicular to the mounting surface.
Orientation: Mount the accelerometer in any orientation, but ensure the sensitive axis (marked by the arrow) is 90 degrees to the rotor axis.
Bolting: Use 0.25 inch or 6 mm bolts to secure the accelerometer. Torque specifications should follow manufacturer recommendations for the specific bolt type.
Cable Connection: Connect the extension cable to the MS3100R-10SL-4P connector and safety wire the connection per standard practices.
The 45357-01 integrates with the Bently Nevada 86517 Accelerometer Interface Module. This system requires charge-coupled accelerometers with sensitivities of either 50 pC/g or 100 pC/g. The 45357-01 meets this requirement with its nominal 50 pC/g sensitivity. Additionally, the system's hazardous area approvals operate on an "entity" basis. This means each component must carry the appropriate certification. The 45357-01 holds CSA certification for Class I, Divisions 1 and 2, ensuring compatibility with certified interface modules. For CENELEC-approved installations, you will need to attach a system cable tag to the interface module field wire.
