Hardware Specifications

Mechanical Monitoring and Signal Behavior

The 3300 XL system uses high-frequency eddy-current probe scaling to convert target proximity into a proportional voltage signal. This extension cable is designed for environments requiring extended temperature range (ETR) performance. Signal integrity relies on maintaining the specified system capacitance; therefore, the cable impedance is precisely controlled to 50 Ohm. Gap voltage validation at the Proximitor end, typically targeting -10 VDC at the nominal gap, must account for the signal path attenuation inherent in the 8.0-meter length. Cross-talk suppression is maintained by ensuring cable shields are continuous and correctly referenced to the system signal common.

Ordering Information

• 330190-080-01-00 ETR Extension Cable unit

• Factory-terminated coaxial connectors

• Integrated stainless steel armor for mechanical protection

• Note: Calibration documentation and mounting clips are excluded from the standard delivery

Field Installation Guidelines

• Routing: Avoid running signal cables in parallel with high-voltage AC lines to prevent electromagnetic coupling.

• Shielding: Ensure the cable shield is grounded at the Proximitor end only; multi-point grounding can create ground loops that induce signal noise.

• Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 in) to prevent damage to the internal dielectric and shielding structure.

• Connector Torque: Use a torque-limiting tool (0.565 N m) for all ClickLoc connections to ensure stable electrical contact.

• Environment: The ETR construction is designed for ambient temperatures up to 260 deg C; verify installation surroundings do not exceed this limit.

Delivery Information

• Delivery time: 2-7 days when payment finish.

• Logistics: Global transit via DHL, FEDEX, or UPS.

• Packaging: All items are secured in anti-static industrial packaging to prevent electrostatic discharge and impact damage during transport.

Frequently Asked Questions

• Q: Can this cable be used with non-ETR probes?

  A: Yes, the cable is electrically compatible with standard 3300 XL probes, though system temperature limits will be defined by the lowest-rated component.

• Q: Why is the cable capacitance important?

  A: The Proximitor sensor is calibrated to compensate for a specific system capacitance; changing cable lengths or types will cause measurement inaccuracies.

• Q: Does the armor affect electrical performance?

  A: No, the armor is purely mechanical and does not influence the electrical transmission characteristics of the coaxial cable.

• Q: How is this cable different from standard 330130 cables?

  A: The 330190 series utilizes materials rated for extended temperature ranges (up to 260 deg C) compared to standard cable construction.

• Q: Is field repair of the connectors permitted?

  A: Field repair is not recommended as it compromises the factory-calibrated impedance and environmental sealing of the connector interface.

• Q: What is the maximum voltage for the signal path?

  A: The signal path operates at low voltage, with the bias supplied by the Proximitor sensor; do not apply external voltage to the signal pins.

• Q: How can I verify cable continuity?

  A: Use a high-impedance multimeter to check for shield continuity and conductor resistance, ensuring no shorts exist between the inner conductor and shield.

• Q: Are the connectors compatible with ClickLoc systems?

  A: Yes, the connectors are designed for seamless integration with all Bently Nevada ClickLoc-equipped proximity systems.
