Installation Guide

1. Mounting: Snap the Proximitor Sensor onto a 35 mm DIN rail (TH35-15 or TH35-7.5 per IEC 60715). Ensure vertical orientation with terminals accessible.
2. Power Supply: Connect -17.5 Vdc to -26 Vdc power supply. Maximum current consumption: 12 mA. When used with intrinsic safety barriers, supply range is -23 Vdc to -26 Vdc.
3. Probe Connection: Connect the 3300 XL 8 mm probe to the Proximitor Sensor via the coaxial connector. Ensure proper torque on the connector.
4. Extension Cable: If using an extension cable, connect it between the probe and the Proximitor Sensor. Total system length (probe + cable) must equal 5.0 meters for this model.
5. Output Wiring: Connect the output signal wires to the monitoring system (e.g., Bently Nevada 3500 Monitoring System). Use shielded cables for noise immunity.
6. Grounding: Connect the ground terminal to a clean earth reference. Avoid ground loops by grounding the shield at one end only.
7. Gap Calibration: Set the probe-to-target gap to approximately 1.27 mm (50 mils) for optimal linear range. Verify output voltage is within the specified linear range.
8. Verification: After installation, verify the output voltage changes proportionally with probe gap movement. Check for stable readings at static positions.

FAQ

Q: What does the model number 330180-51-00 mean?
A: 330180 = 3300 XL Proximitor Sensor; 51 = 5.0 m system length, DIN rail mount; 00 = no agency approvals required.

Q: Can I use a 9-meter extension cable with this sensor?
A: No. The 330180-51-00 is calibrated for a 5.0-meter total system length. Using a different length will result in incorrect sensitivity and linearity. For 9-meter systems, order 330180-91-00 or 330180-91-05.

Q: Is this sensor compatible with 3300 5 mm probes?
A: Yes. The 3300 XL 8 mm Proximitor Sensor is backward compatible with 3300 series 5 mm probes. However, sensitivity and linear range will correspond to the 5 mm probe specifications.

Q: What monitoring systems are compatible?
A: The 330180-51-00 is compatible with Bently Nevada 3500, 3300, and 1900/65 monitoring systems, as well as third-party systems accepting -24 Vdc proportional voltage inputs.

Q: Does this model have hazardous area approvals?
A: No. The -00 suffix indicates no agency approvals. For hazardous area applications, select models with -05 (multiple approvals including CSA, ATEX, IECEx) or other approval suffixes.

Selection Tips

• Verify total system length required: 5.0 m (order -51- or -50-) or 9.0 m (order -91- or -90-).
• Verify mounting type: DIN rail (-51- or -91-) or panel mount (-50- or -90-).
• Verify agency approvals: None (-00), multiple (-05), or country-specific (-CN).
• Ensure the probe target material matches the factory calibration (default: AISI 4140 steel). Custom calibration for other materials is available upon request.
• When replacing a failed unit, always match the exact model number including all suffixes to ensure identical electrical and mechanical characteristics.
• For systems requiring intrinsic safety barriers, ensure the supply voltage remains within -23 Vdc to -26 Vdc to maintain full linear range.
