The 190501‑07‑00‑00 Bently Nevada Velomitor CT Velocity Transducer is a piezo‑velocity vibration sensor engineered for low‑frequency vibration monitoring on industrial equipment — especially
cooling tower fans and air‑cooled heat exchanger fan assemblies operating at low speeds (as slow as ~90 RPM). It’s part of the Velomitor CT family, optimized to
detect casing vibration velocity and provide reliable signals for machinery protection and condition monitoring systems.

FAQ Q: What does a Velomitor CT velocity transducer measure?A: It measures casing vibration velocity of rotating equipment, especially at low operating speeds (down to ~90 RPM). Q: What is the sensitivity and frequency range?A: The sensor typically has 3.94 mV/mm/s (100 mV/in/s) ±5% sensitivity, with an operating frequency range from about 3 Hz up to 900 Hz (±1 dB), extendable to 1 kHz ±3 dB. Q: Can it be used with long cable runs?A: Yes — the Velomitor CT design supports cable lengths up to around 305 m (1,000 ft) while maintaining signal integrity. Q: What environments can it operate in?A: Many variants are durable for industrial environments. Certain suffix versions (like hazardous area options) carry ATEX, IECEx, and CSA certifications. |
