Rotor Dynamics and Cross-Talk Suppression

The 330500-00-20 utilizes a piezoelectric seismic sensing element to capture case-referenced vibration velocity. For accurate rotor dynamics interpretation, the transducer provides a linear output scaled at 100 mV/in/s. To prevent signal degradation and maintain measurement fidelity, cross-talk suppression is maintained by ensuring the sensor is isolated from extraneous structural vibrations not representative of the monitored bearing housing. Signal cable shielding must be strictly maintained throughout the conduit run to prevent electromagnetic interference from skewing the low-amplitude velocity output.

Frequently Asked Questions

Q: Can the 330500-00-20 be mounted in any orientation?

A: Yes. The seismic sensing element within the Velomiter allows for omnidirectional mounting, though it is standard practice to align the sensor axis with the primary radial or axial vibration component of interest.

Q: Is this sensor loop-powered?

A: Yes. The device requires a constant current source (2 mA to 10 mA) provided by the vibration monitor or signal conditioner to operate the internal integrated electronics.

Field Installation Guidelines

Prepare a flat, smooth mounting surface. Ensure the surface is free of paint or debris to maximize high-frequency vibration transmission.
Use a hardened mounting stud or appropriate adapter to secure the sensor. Ensure the connection is torqued to manufacturer guidelines to avoid mechanical resonance issues.
Use shielded, twisted-pair cabling for the 2-pin connector interface. Verify the shield is connected only at the monitor terminal to prevent ground loops.
Ensure the cable is secured with clamps at frequent intervals to prevent cable-whip, which can manifest as low-frequency noise in the vibration spectrum.
Prior to system finalization, perform a bias voltage check at the monitor input to confirm the transducer electronics are energized correctly.
