Bently Nevada 190501-10-00-00 Low-frequency velocity (Velomitor CT) transducer

FAQ

Q1: What is the purpose of the 190501-10-00-00 transducer?
A1: It is a low-frequency velocity transducer (Velomitor CT) intended for measuring casing vibration in cooling towers and air-cooled fan systems, particularly where slow shaft speeds or low vibration levels are expected.

Q2: What makes the “10” suffix variant different from base models?
A2: The “10” in the model suffix typically identifies a specific configuration—such as mounting options or internal tuning—within the series of Velomitor CT models.

Q3: What is the operational temperature range?
A3: The transducer can reliably operate between –40 °C and +100 °C, making it suitable for outdoor fan and ambient conditions.

Q4: What is the size and weight of this transducer?
A4: Its diameter is around 33 mm (1.30 in), and it weighs approximately 0.11 kg.

Q5: Does it support very low frequencies?
A5: Yes — the Velomitor CT line is designed for low-frequency response, down to about 0.1 Hz, so it can capture slow vibration components.

Q6: What kind of output does this provide?
A6: It provides a velocity output (voltage) suited to vibration monitoring instrumentation; it is not a current loop device.

Q7: How is it mounted and connected?
A7: It uses a MIL-C-5015 connector interface. Some variants include a mounting stud; others are flange or bare sensor types depending on the suffix choice.

Q8: Is it suitable for high-speed machinery?
A8: While primarily intended for lower speed and low-frequency applications (such as cooling tower fans), it can handle higher frequencies up to ~10 kHz, so it may be used in broader vibration monitoring applications, provided the vibration levels remain within its range.
