Installation Instructions

1. Preparation: Ensure the shaft surface is clean and the mounting location for the probe is flat and perpendicular to the axis of measurement.

2. Mounting the Probe: Thread the proximity probe into the mounting port until the tip is approximately 1 mm (40 mils) from the shaft. Use the supplied jam nut to secure the probe.

3. Cable Routing: Route the cable carefully to avoid sharp bends and interference. Use cable clamps to secure the cable.

4. Connecting the Extension Cable: Attach the extension cable to the probe connector and tighten the coupling nut securely.

5. Connect to Proximitor Sensor: Connect the other end of the extension cable to the Proximitor® sensor input.

6. System Testing: Verify signal output with a Bently Nevada signal conditioner or 3500 monitor. Confirm linear response and sensitivity.

7. Calibration and Alignment: Calibrate per API 670 standards or manufacturer recommendations. Fine-tune probe gap using a dial gauge.

FAQ (Frequently Asked Questions)

Q1: What is the primary function of the 330703-000-050-10-01 probe?
A1: It is used for non-contact measurement of shaft position and vibration in rotating machinery. It converts physical displacement into electrical signals used for condition monitoring.

Q2: Is this model compliant with API 670 standards?
A2: Yes, the 330703 series is fully compliant with API 670 standards for vibration monitoring and machinery protection.

Q3: Can I use this probe in high-temperature environments?
A3: While the standard version supports up to 120°C, for higher temperatures, the 330980 series Proximitor® sensors with high-temp capabilities should be used in combination.

Q4: How do I determine the correct probe gap?
A4: The probe gap is typically set around 1 mm (40 mils) but should be fine-tuned using a dial indicator for accuracy during installation.

Q5: What is the difference between this model and 330703-000-080-10-01?
A5: The main difference lies in the probe length. The 330703-000-080-10-01 has an 80 mm probe compared to the 50 mm in the 330703-000-050-10-01, allowing deeper mounting points.

Q6: What tools are recommended for installation?
A6: A standard torque wrench, dial gauge, jam nut wrench, and alignment tools for shaft positioning are commonly used for accurate installation.
