Bently Nevada 190501-00-00-00 CT Velomitor Velocity Transducer — new, unused, open box (original factory packaging opened, item never installed or put into service).
This is the low-frequency variant of the standard Velomitor piezo-velocity sensor, purpose-built to measure casing vibration velocity on cooling tower and air-cooled heat exchanger fan assemblies operating at or above 90 RPM (100–300 RPM typical). It captures both the low-frequency fan vibration and the higher-frequency signature from the motor and speed reducer — a measurement range standard Velomitors can't reliably cover.
Specifications:
• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%
• Frequency response: 3.0–900 Hz ±1.0 dB / 1.5 Hz–1.0 kHz ±3.0 dB
• Velocity range: 63.5 mm/s pk (2.5 in/s pk)
• Max cable length: 305 m (1,000 ft)
• Operating temp: -40°F to 185°F (-40°C to 85°C)
• Compatible with Bently Nevada 3500 and 3300 monitoring systems |Field |Value |Bently Nevada |
