• Extension cables matched to installation requirements
• 3300 series rack with power supply module
• Relay output module for alarm integration

Common Questions & Answers

Q: What is the difference between single and dual-channel thrust monitors?
A: Dual-channel monitors like the 3300/20-12-01-02-00-00 provide redundant measurement paths. If one channel fails, the second continues operation, preventing false trips and ensuring continuous protection. This is essential for API 670 compliance in critical machinery applications.

Q: Can this monitor work with existing 3300 XL proximitor sensors?
A: Yes, the 3300/20 series is fully compatible with all Bently Nevada 3300 XL proximitor sensors including 8mm and 11mm probe configurations. Factory calibration accounts for standard sensor system characteristics.

Q: What maintenance is required for this thrust position monitor?
A: The module itself is maintenance-free. Recommended practice includes annual verification of alarm setpoints, visual inspection of connections, and periodic comparison of dual-channel readings to verify sensor system health.

Q: How quickly can this unit be shipped for emergency replacements?
A: We maintain ready stock for critical 3300 series modules. Express shipping options are available for urgent machinery protection needs, with global logistics support to minimize downtime.
