Applications and Use Cases for the Velomitor CT Transducer

In rotating machinery monitoring, the 190501-19-00-CN excels at detecting early signs of imbalance or misalignment. It is ideal for pumps, fans, compressors, and turbines where reliable velocity output is critical. Moreover, its wide operating temperature range makes it suitable for outdoor or extreme environment installations.

Installation and Mounting Guide

Mount the transducer on a 33 mm diameter surface using the provided adapter (3/8-in 24 to 1/4-in 18 NPT). Apply a mounting torque of 4.5 N-m ± 0.6 N-m to ensure proper coupling. The transducer can be oriented at any angle, and the MIL-C-5015 connection interface simplifies wiring. Pin A goes positive with respect to Pin B when velocity is from base to top.

Maintenance and Reliability Tips

Regularly inspect the transducer for physical damage or corrosion, especially in condensing humidity environments. The internal electronics are isolated from the case, reducing ground loop issues. For long-term reliability, verify that the cable length does not exceed 305 metres to maintain signal integrity.

Troubleshooting Common Issues

If output bias voltage deviates from 10.1 Vdc ± 1.0 Vdc, check the cable connections and ensure proper grounding. Transverse response should be less than 5% of axial sensitivity; higher values may indicate misalignment. For amplitude linearity issues, confirm the vibration level is within ±2% to 63.5 mm/s pk.
