FAQ and Selection Guide

• What is the advantage of the Velomitor CT over standard sensors?
• The CT version specifically monitors low-frequency vibrations in cooling towers.
• Does this model include intrinsically safe certifications?
• Yes, the -04 option provides ATEX, IECEx, and CSA Class I Division 1.
• How do I select the correct mounting option?
• Verify your machine’s tapped hole size; the -12 option fits M8x1 threads.
• Can I use this sensor with non-Bently Nevada monitors?
• Yes, if the system accepts a 100 mV/in/s constant current input.
• What is the recommended calibration interval?
• Industry standards suggest verifying sensitivity and bias voltage every 24 months.
