Rotor Dynamics and Signal Integrity

The 330500-04-00 Velomitor utilizes an internal piezoelectric element and integrated circuitry to provide a velocity-proportional output. Unlike eddy-current probes that require -10 VDC targets for gap voltage validation, this sensor outputs a signal based on the casing vibration intensity. To maintain measurement fidelity, ensure the mounting surface is machined flat to minimize high-frequency attenuation. Cross-talk suppression is achieved by utilizing shielded cabling and preventing cable loops that can act as induction antennas for electromagnetic noise, which would otherwise obscure low-frequency vibration data required for monitoring machine health.

Frequently Asked Questions

Q: Can this sensor be mounted on any surface orientation?

A: Yes. The piezo-velocity sensor is omnidirectional regarding gravity, but the mounting surface must be rigid and free of paint or corrosion to ensure accurate transmission of casing vibration.

Q: Is there a specific torque requirement for the 1/4-20 UNC stud?

A: Yes. The sensor must be torqued to a value that ensures a secure, high-frequency coupling with the machine casing. Avoid over-torquing, which may strip the threaded interface or induce stress on the internal sensor housing.

Field Installation Guidelines

Machine the mounting surface to a flat finish to guarantee full contact area for the transducer base.
Apply a thin layer of silicone grease to the mounting interface to improve high-frequency energy transfer if the surface finish is not ideal.
Install the sensor using the 1/4-20 UNC stud. Tighten until the sensor base is fully seated against the machine casing.
Route the interface cable away from high-voltage lines and variable frequency drive outputs to minimize induced noise.
Secure the cable at frequent intervals to prevent movement and "cable whip," which introduces false vibration signals into the monitor input.
