Functional Characteristics
The 190501-19-00-04 transducer is designed to capture low‑frequency casing vibration velocity, making it suitable for cooling tower fans, air‑cooled heat exchangers, and other slow‑speed rotating assets. Its internal sensing element is tuned to detect vibration amplitudes associated with unbalance, misalignment, and gearbox issues common in low‑RPM machinery.
The rugged stainless‑steel enclosure ensures long‑term durability in outdoor and corrosive environments. Proper mounting on bearing housings or structural casings allows the sensor to accurately represent true vibration levels without distortion or signal loss.
Its compact form factor enables installation in tight spaces while maintaining full measurement accuracy. The Velomitor CT design provides reliable condition monitoring where standard piezoelectric sensors may not deliver adequate low‑frequency response.
Application Scenarios
Suitable for vibration monitoring on:
-
Cooling tower fan assemblies
-
Air‑cooled heat exchanger fans
-
Slow‑speed industrial fans (90–300 RPM)
-
Gear-driven fan systems
-
Outdoor rotating equipment exposed to harsh conditions
FAQ
Q: What makes the Velomitor CT suitable for low‑speed machinery? A: Its sensing element is optimized for low‑frequency vibration, enabling accurate detection on equipment running below typical industrial speeds.
Q: Can this sensor be used outdoors? A: Yes. The 316L stainless steel housing provides excellent corrosion resistance for outdoor and humid environments.
Q: Where should the sensor be mounted? A: It should be installed directly on bearing housings or rigid machine casings to ensure accurate vibration transmission.
