Rotor Dynamics and Signal Integrity

The 330500-00-00 sensor utilizes an internal piezoelectric element to convert mechanical casing acceleration into a velocity-proportional electrical signal. Unlike eddy-current displacement sensors that necessitate precise gap voltage validation (-10 VDC targets) to determine shaft relative position, this Velomitor provides a continuous output reflecting absolute seismic intensity. To maintain measurement fidelity, implement effective cross-talk suppression by utilizing shielded instrumentation cabling. Ensure the cable is routed away from high-power AC lines or variable frequency drive conductors to prevent electromagnetic interference from distorting the low-level signal stream.

Frequently Asked Questions

Q: Does the 316L stainless steel housing provide shielding against electrical interference?

A: Yes, the hermetically sealed stainless steel shell provides environmental durability and contributes to electromagnetic shielding. Ensure the case is properly grounded at the monitor end to maximize noise immunity.

Q: Can the sensor be mounted using a custom adapter?

A: The 330500-00-00 is supplied without a thread adapter. If a custom adapter is utilized, it must be fabricated from rigid materials and machined to maintain a flat, full-contact interface with the machine casing to prevent high-frequency signal attenuation.

Field Installation Guidelines

Machine the mounting surface to a flat, smooth finish to ensure a rigid, full-contact area for the sensor base.
Apply a thin layer of silicone grease to the transducer base to facilitate high-frequency energy transfer at the mounting interface.
Tighten the sensor firmly against the casing, ensuring the 46 kg cm (40 in-lb) maximum torque limit is not exceeded.
Route the 2-pin Mil-C-5015 connector cable away from high-current conductors and switching power supplies to mitigate induced electrical noise.
Verify the bias voltage at the monitoring system input terminals during commissioning to ensure the transducer is correctly energized.
