Technical Hardware Specifications

TSI Mechanical Monitoring Characteristics

Reliable vibration monitoring requires precise eddy-current probe scaling. This probe is designed to integrate with 3300 XL Proximitor sensors, maintaining a target gap voltage of -10 VDC at the linear range center. Rotor dynamics data accuracy is dependent on the stability of this signal. To ensure cross-talk suppression, technicians must adhere to spacing requirements when installing multiple probes, preventing frequency interference between adjacent sensing elements within the machine housing.

Ordering Info

• 1 x 330102-00-60-10-01-05 8 mm Proximity Probe

• 2 x 3/8-24 UNF mounting nuts

• 1 x Connector protector

• 1 x Technical documentation package

Field Installation Guidelines

• Surface Prep: Ensure the target shaft surface is clean and meets the required finish (0.8 micrometer Ra).

• Mounting Torque: Tighten mounting nuts to 6.8 N m (60 in-lb) to ensure structural integrity without distorting the probe housing.

• Grounding: Terminate the coaxial shield at the monitor rack to maintain an effective ground path and minimize signal noise.

• Conduit Routing: Enclose the coaxial cable in a dedicated, grounded metallic conduit to protect against electromagnetic interference.

Frequently Asked Questions

• Can this probe be field-cut to a different length? No, the system is factory-calibrated for the specific cable length; altering it will invalidate the measurement.

• What is the primary cause of signal failure? Short circuits or open circuits in the coaxial cable usually trigger a "Not OK" status in the monitor rack.

• Can I use this probe in underwater applications? The probe is designed for machine environments; confirm specific pressure and fluid compatibility before immersion.

• Is the connector waterproof? The provided connector protector prevents moisture ingress, but it is not intended for high-pressure submersion.

• How do I calibrate the gap voltage? Use a feeler gauge to set the physical gap while monitoring the DC output voltage at the Proximitor terminals.

• Does this probe support hot-swapping? No, power must be disconnected from the Proximitor sensor before replacing the probe or cable.

• Can I use a non-Bently Nevada extension cable? No, impedance mismatching will result in significant signal reflection and measurement errors.

• What signifies that the probe is outside its linear range? An output voltage near the supply rail limit typically indicates the probe is too far from the target.
