Frequently Asked Questions
Why does the Velomitor combine piezoelectric elements with internal signal integration?
This design provides the wide frequency response and mechanical durability of a piezoelectric accelerometer while electrically integrating the output to yield a direct velocity signal.
What is Global PLC Spare HUB's Insight on proper mounting torque for 3/8-16 studs?
Global PLC Spare HUB recommends tightening the sensor to a maximum torque between 32 and 46 kg cm (24 to 40 in-lb) using a flat mounting pad to prevent base strain sensitivity errors.
How does base strain affect velocity sensor output accuracy?
Excessive mechanical torque or mounting pad distortion can induce base strain artifacts; using a clean, flat surface keeps base strain sensitivity well below the 0.005 in/s/mstrain threshold.
What precautions are necessary when routing long signal cables in high-noise environments?
Always use recommended shielded cables (such as part number 02173006) up to 305 meters, and ground the cable shield at the monitor end to eliminate electromagnetic interference.
Why is case isolation critical for industrial velocity measurements?
Case isolation prevents ground loops between the sensor housing and machine frame, ensuring clean signal transmission without 50/60 Hz power frequency noise contamination.
