Hardware Specifications

Mechanical Monitoring & TSI Characteristics

The 3300 XL extension cable is engineered with a standard capacitance of 69.9 pF/m to maintain system-wide impedance matching, which is vital for the -10 VDC gap voltage calibration of the Proximity Transducer System. The armored construction provides physical protection against harsh industrial environments, while ensuring electromagnetic shielding to minimize signal cross-talk in dynamic vibration monitoring. This cable supports complete component interchangeability, allowing field replacement without requiring individual component matching or system-wide recalibration. The assembly is designed to maintain signal linearity and thermal stability under the rigorous conditions specified by the API 670 standard.

Frequently Asked Questions

Q: Does the addition of armor affect the electrical performance of the extension cable?

A: No. The armored cable construction is designed to protect the integrity of the coaxial signal path without altering the characteristic impedance or capacitance, ensuring consistency in the output signal.

Q: Is it permissible to field-splice or shorten the 4.5-meter extension cable?

A: No. Modifying the cable length or connector assembly will alter the system impedance, directly affecting the Proximitor sensor output and invalidating the transducer system calibration.

Field Installation Guidelines

• Ensure that the connector assembly is protected from oil and moisture ingress using the supplied connector protectors.
• Maintain the minimum bend radius when routing the armored cable to avoid permanent deformation of the inner coaxial structure.
• Verify that the cable is secured to the machinery casing using vibration-resistant clamps to prevent conductor fatigue caused by high-frequency machinery cycles.
• Clean all connection interfaces with a lint-free swab and appropriate solvent before mating to ensure a low-resistance electrical contact.
• Perform a gap voltage check at the Proximitor sensor output after cable installation to confirm proper system connectivity.
