Hardware Specifications

Mechanical Monitoring and Transducer Performance

The 190501 Velomitor CT transducer is optimized for low-frequency vibration monitoring, maintaining consistent performance across the 3 Hz to 900 Hz bandwidth. Precise transducer orientation relative to the vibration source is required to minimize transverse response, which is limited to less than 5% of the axial sensitivity. Maintaining signal linearity and minimizing noise requires high-integrity cable shielding, similar to standard eddy-current probe scaling practices. Proper mounting ensures that the casing vibration data accurately reflects rotor dynamics characteristics transmitted to the machine structure.

Field Installation Guidelines

• Surface Preparation: Clean the mounting surface to ensure flat, metal-to-metal contact with the transducer base to maintain high-frequency response.
• Mounting Torque: Utilize the specified mounting bolt and torque settings to prevent mechanical resonance of the transducer mount itself.
• Connector Integrity: Secure the MIL-C-5015 connector and verify that the mating cable assembly is properly strain-relieved to prevent intermittent electrical contact.
• Signal Shielding: Use shielded twisted-pair cabling and ensure the shield is grounded at only one end to prevent ground loops.

Frequently Asked Questions

• Can this transducer be used for high-frequency measurements?

  The Velomitor CT is optimized for low-frequency applications (3 Hz to 900 Hz). Higher frequency vibrations should be monitored with appropriate piezoelectric sensors.

• Does the transducer require external power?

  Yes, the Velomitor requires an external DC power source, typically provided by the monitoring system interface, to operate its internal signal conditioning circuitry.

• What is the significance of the MIL-C-5015 connection?

  This connector type is a standard industrial interface that provides a rugged, environmentally sealed connection for signal transmission in demanding conditions.

• Is the transducer output polarity sensitive?

  Yes, the output signal polarity corresponds to the direction of vibration relative to the sensor axis; ensure correct wiring polarity during installation.

• How is the transverse response verified?

  Transverse response is a factory-determined characteristic; in the field, ensure the mounting axis is strictly aligned with the primary vibration direction.

• What are the consequences of improper surface mounting?

  Poor mounting surfaces or loose bolts will introduce mechanical amplification or attenuation, causing non-linear response and inaccurate vibration data.

• Does the transducer have internal calibration?

  The sensitivity is factory-calibrated. Field verification is limited to measuring the output signal against a known vibration source.

• Can this sensor be used in hazardous locations?

  The current model (190501-00-00-00) includes no agency approvals; do not install in explosive atmospheres unless the specific unit is rated for the environment.
