Mechanical Monitoring and Signal Validation
This probe requires precise eddy-current probe scaling to ensure accurate voltage-to-displacement conversion through the associated 3300 XL Proximitor. During installation, perform gap voltage validation (-10 VDC targets) to verify the probe is positioned within the specified linear range relative to the shaft surface. Cross-talk suppression is maintained by adhering to minimum probe spacing requirements, which prevents interference between excitation frequencies of adjacent sensors. The probe tip is designed for continuous operation in environments subject to high-pressure fluids, provided the installation does not exceed the 200 psi rating. Ensure the probe and extension cable assembly maintains a consistent characteristic impedance of 50 ohms to minimize signal reflections.
Frequently Asked Questions (FAQ)
Q: Can this probe be connected directly to a PLC or must it interface with a Proximitor?
A: The probe must interface with a Bently Nevada 3300 XL Proximitor. The Proximitor provides the necessary high-frequency carrier signal for eddy-current generation and converts the probe's raw output into a standard 4-20 mA or proportional voltage signal.
Q: Is the probe output affected by the metallurgical composition of the target surface?
A: Yes. The probe is factory-calibrated for 4140 steel. If the target material differs, such as non-magnetic stainless steel or non-ferrous metals, a scaling factor must be applied to the data to compensate for variations in magnetic permeability and conductivity.
Field Installation Guidelines
- Mounting: Ensure the M10 × 1 mounting bracket is rigid and free of excessive vibration. Use the provided lock nuts to secure the probe body, ensuring the tip is at the required nominal gap of 1.0 mm from the shaft.
- Grounding: Route the probe and extension cable through an oil-tight conduit to protect against physical damage and EMI. Ensure the cable shield is continuous and grounded at the monitoring rack end only to prevent ground loops.
- Sealing: Apply an appropriate thread sealant to the mounting threads if the installation occurs in a pressurized environment, ensuring the sealant does not obstruct the probe tip or the sensing field.
- Validation: After physical mounting, apply power to the Proximitor and measure the DC gap voltage at the monitor terminal block. Adjust the probe position until the reading is exactly -10 VDC (or the specific setpoint required by the machine configuration).
