190501 is a Velomitor CT Velocity Transducer Manufactured by Bently Nevada and used in Machinery Condition Monitoring. A low-frequency variation of the Velomitor Piezo-velocity Sensor is the Velomitor CT Velocity Transducer. Its design takes into account the casing vibration velocity of the cooling tower and air-cooled heat-exchanger fan assemblies that run at or above 90 rpm (100 to 300 rpm typical). Velomitor CT Transducer can detect amplitudes of vibration at these frequencies, as well as those produced by the fan motor and speed reducer.
- The majority of machine problems (unbalance, misalignment, etc.) occur on the rotor and start with an increase (or at least a change) in rotor vibration. To be useful for overall machine safety, any individual casing measurement must continuously transfer a considerable amount of rotor vibration to the machine casing or transducer mounting point.
- Furthermore, ensure that the accelerometer transducer is installed on the bearing housing or machine casing. Improper installation may reduce the amplitude and frequency response of the transducer and/or provide erroneous signals that do not represent actual vibration. Consult the applicable instruction manuals and Application Notes. Bently Nevada may provide engineering services to find suitable machine housing measurements and installation support upon request.
190501 Functional Description
A low-frequency variation of our conventional Velomitor Piezo-velocity Sensor is the Velomitor CT Velocity Transducer. With fan assemblies for cooling towers and air-cooled heat exchangers running at or above 90 rpm, it is designed to monitor the casing vibration velocity (100 to 300 rpm typical). These vibration amplitudes can be measured by the Velomitor CT Transducer in addition to the vibration frequencies produced by the fan motor and speed reducer.
- Sensitivity: 3.94mV/mm/s (100 mV/in/s) ±5%.
- Frequency Range: Adjusted frequency range to 3.0 Hz to 900 Hz 1.0 dB or 1.5 Hz to 1.0 kHz 3.0 dB to allow velocity sensor to measure vibration for fans running at as low as 90 rpm.
- Cabling: Maximum cable length is 305 m. (1,000 ft).
- Parameters are defined in the range of +20 °C to +30 °C (+68 °F to +86 °F) and 100 Hz.
- Weight: <297 g (10.5 oz.)
- Mounting Surface: 33 mm diameter (1.3 in diameter)
- Height: 82 mm (3.2 in)
- Case Material:316L stainless steel
- Casing Vibration Velocity is measured.
- Cooling Towers and Air-Cooled Heat-Exchanger Fan Assemblies are compatible.
- 33 mm diameter mounting surface (1.3 in diameter).
- 82 mm in height (3.2 in).
- 316L stainless steel is used for the case. MIL-C5015 2-pin 316L stainless steel connector, top.
- 4.5 N-m 0.6 N-m (40 in-lbf 5 in-lbf) mounting torque
- When the velocity is measured from the bottom to the top of the transducer, Pin A becomes positive in relation to Pin B.
- Angle of Mounting: Any orientation.
- Plate Stud M6x1 to M6x1 with 3/8-in 24 Adapter
- MIL-C-5015 Connection Interface
- Multiple Approvals
- Operating Temperature: -40°C to +85°C
- Storage Temperature: -40°C to +100°C
- Shock Limit: 5000 g pk, maximum.
- Humidity Limit: 100% condensing,non-submerged.
- Magnetic Field Susceptibility: <0.0068 mm/s/gauss (0.268mil/s/gauss) @ 50 gauss, 50-60Hz
- Carefully assemble the transducer. If you don't, the transducer might not detect vibrations accurately and might convey false information. For the precise measurement of machine housings and the installation of transducers, Bently Nevada offers engineering services.
- Think about the kind of data you need to collect before measuring a machine housing to determine where to attach transducers. The majority of typical machine issues (imbalance, misalignment, etc.) start at the rotor and affect the vibration of the rotor. The housing must accurately transmit rotor vibration to the transducer at the place you choose.
- Consider the usefulness of the measurement for each application if you intend to make housing measurements for overall machine protection. The majority of common machine malfunctions (imbalance, misalignment, etc.) begin at the rotor and result in an increase (or at least a change) in rotor vibration. To be effective for overall machine protection, any housing measurement must faithfully transmit a significant amount of rotor vibration to the bearing housing or machine casing, or more specifically, to the transducer mounting location.
- When physically installing the transducer, use caution. Improper installation can reduce transducer performance and/or generate signals that do not accurately represent machine vibration.
