Configured for non-contact shaft displacement measurement within the 3300 XL 8 mm Proximity Transducer System, the Bently Nevada 330910-00-11-10-02-05 (330910-00-11-10-02-05 Proximity Probe) provides direct physical and electrical execution of dynamic gap signal acquisition.

Model Configuration Matrix

The 330910-00-11-10-02-05 probe serves as the primary sensor interface for radial vibration, axial position, and speed measurement applications. It is designed for installation in compatible transducer housing assemblies and requires a matched Proximitor sensor for output signal conditioning.

Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The 330910 probe utilizes an eddy-current sensing coil to detect shaft movement. During installation, the probe must be scaled to ensure output linearity relative to the target material. Technicians must perform gap voltage validation, targeting -10 VDC as the operational midpoint, to maintain consistent rotor dynamics monitoring. This process minimizes signal distortion and ensures accurate frequency response for vibration analysis. Proper cross-talk suppression techniques are required during cable routing to prevent electromagnetic interference between adjacent probe channels, which preserves the fidelity of the raw signal sent to the protection monitors.

Field Installation Guidelines

• Mount the probe in the machine casing, maintaining the required standoff distance from the target surface.

• Use lock nuts to secure the probe position after establishing the operational gap.

• Connect the probe cable to the extension cable and Proximitor sensor, ensuring the ClickLoc connector is fully tightened to provide a stable, low-resistance connection.

• Verify the gap voltage using a digital multimeter at the Proximitor sensor output during machine standstill.

• Ensure cabling is shielded and segregated from high-power AC lines to reduce potential for noise-induced measurement error.

Frequently Asked Questions

• Q: Is this probe interchangeable with different cable lengths?

  A: No, the 3300 XL transducer system is calibrated as a matched set consisting of the probe, extension cable, and Proximitor; modifying lengths voids calibration.

• Q: Can the probe be used in hazardous area applications?

  A: The probe is intrinsically safe when installed as part of an approved system configuration; consult the official system control drawing for zone compatibility.

• Q: How do I check for probe saturation?

  A: Saturation occurs if the probe is moved too close to the target, resulting in voltage levels approaching 0 VDC, which indicates the sensor is out of its linear range.

• Q: Is the probe tip susceptible to damage?

  A: The tip is made of a reinforced plastic; avoid mechanical impacts during installation, as damage to the tip will alter the sensing coil properties and measurement accuracy.

• Q: Can it measure non-metallic targets?

  A: The eddy-current principle requires a conductive target material; non-metallic targets will not generate the necessary signal.

• Q: How does ambient temperature affect the probe?

  A: The probe is compensated for temperature effects between -40 deg C and +125 deg C, provided the Proximitor sensor remains within its specified operating range.

• Q: What is the purpose of the stainless steel housing?

  A: It provides chemical resistance against process fluids and physical protection in high-vibration industrial settings.

• Q: How is the probe cable protected?

  A: The probe is typically supplied with an integrated protective armor to guard against mechanical damage and environmental contaminants.
