FAQ
A1: Yes, it connects directly to both 3300 and 3500 monitoring platforms without signal conditioning modules.
Q2: Can this sensor withstand high vibration levels?
A2: Yes, its piezoelectric construction handles continuous industrial vibration, and it endures high shock loads.
Q3: What frequency range does the Velomitor sensor support?
A3: It typically covers 10 Hz to 1,000 Hz, providing broad coverage for rotating machinery.
Q4: Does the sensor require periodic recalibration?
A4: Not usually, because the solid-state design maintains long-term accuracy under stable installation conditions.
Q5: Can I mount the sensor in any orientation?
A5: Yes, various mounting thread options support flexible installation on horizontal and vertical surfaces.
Q6: Is it suitable for outdoor environments?
A6: Yes, the stainless-steel enclosure and internal shielding ensure reliable operation in harsh plant environments.
