Installation Guide

1. Hazardous Area Compliance: Verify the installation area classification matches the sensor's approval ratings (CSA, ATEX, IECEx). Install per local hazardous area wiring codes.
2. Mounting: Snap onto a 35 mm DIN rail (TH35-15 or TH35-7.5). Ensure the mounting location is within the approved temperature range and protected from direct exposure to explosive atmospheres if not rated for direct exposure.
3. Power Supply: Connect -17.5 Vdc to -26 Vdc. Max current: 12 mA. With intrinsic safety barriers: -23 Vdc to -26 Vdc.
4. Intrinsic Safety: When used in hazardous areas, install appropriate intrinsic safety barriers between the sensor and the monitoring system. Verify barrier compatibility with the sensor's entity parameters.
5. Probe & Cable: Connect the 3300 XL 8 mm probe and extension cable. Total system length must equal 5.0 meters.
6. Output Wiring: Route shielded cables to the monitoring system. Ground the shield at the monitoring system end only to prevent ground loops in hazardous areas.
7. Gap Calibration: Set probe-to-target gap to approximately 1.27 mm (50 mils). Verify linear output range.
8. Documentation: Retain all hazardous area certificates and installation instructions for regulatory inspections.

FAQ

Q: What approvals does the 330180-51-05 carry?
A: The -05 suffix indicates multiple approvals including CSA (US and Canada), ATEX (European), and IECEx (international). Specific approval markings are printed on the sensor label. Refer to the official datasheet for complete approval details and entity parameters.

Q: Can I use this sensor in a Zone 0 area?
A: The 330180-51-05 is approved for use with appropriate intrinsic safety barriers. Verify the specific Ex rating (e.g., Ex ia IIC T4) on the sensor label against your area classification requirements. Consult the official hazardous area certificate for detailed installation conditions.

Q: What is the difference between 330180-51-00 and 330180-51-05?
A: The only difference is the agency approval option. The -51-00 has no approvals; the -51-05 has CSA, ATEX, and IECEx approvals. Electrical and mechanical specifications are identical.

Q: Is intrinsic safety barrier required?
A: Yes, when installed in hazardous areas. The sensor must be connected through approved intrinsic safety barriers. The barrier must be compatible with the sensor's entity parameters (voltage, current, capacitance, inductance).

Selection Tips

• Always verify your plant's hazardous area classification before selecting the approval option. The -05 suffix covers most North American and European requirements.
• For country-specific approvals (e.g., China), look for -CN suffix variants.
• When replacing a sensor in a hazardous area, never downgrade from an approved model to a non-approved model — this violates safety regulations.
• Ensure intrinsic safety barriers are properly rated for the sensor's electrical parameters and the area classification.
• Keep hazardous area certificates on file for audits and inspections. Certificates are available from Bently Nevada upon request.
