Bently Nevada 190501-09-99-01 Velomitor CT Velocity Transducer

190501-09-99-01 belongs to the Velomitor CT family of case-mounted seismic velocity transducers. It converts machine casing motion into a voltage signal proportional to vibration velocity for continuous machinery-condition monitoring.

Product Profile

190501-09-99-01 belongs to the Velomitor CT family of case-mounted seismic velocity transducers. It converts machine casing motion into a voltage signal proportional to vibration velocity for continuous machinery-condition monitoring.

The Velomitor CT provides 100 mV/in/s sensitivity. Frequency response extends from 3 Hz to 900 Hz within ±1 dB and from 1.5 Hz to 1 kHz within ±3 dB, making it suitable for machinery where low-frequency casing vibration is an important condition indicator.

The internal electronics are isolated from the case. The transducer operates from -40°C to +85°C, withstands 5000 g peak shock and supports long field wiring to compatible monitoring equipment.

System Role

Velocity Signal Generation
190501-09-99-01 converts machine casing motion into a voltage signal proportional to vibration velocity for continuous condition monitoring.
Low-Frequency Measurement
The Velomitor CT family extends useful response to 1.5 Hz at the ±3 dB limit, supporting machinery with important low-frequency vibration content.
Case-Isolated Electronics
Internal electronics are isolated from the transducer case, supporting stable signal transmission in industrial installations.
Permanent Monitor Interface
The transducer is intended for continuous connection to a compatible velocity-monitoring input with the correct excitation and polarity.
Long Field Wiring
The signal can be carried over extended field wiring within the manufacturer's documented cable and installation limits.
Seismic Case Measurement
Unlike a proximity probe, the Velomitor CT measures machine casing or bearing-housing motion and does not require a shaft target.

Compatibility

Confirm the complete configuration, mating components, mounting details and approval requirements before substitution.

Applications

Bearing-Housing Monitoring
190501-09-99-01 measures vibration velocity directly from the bearing housing or machine casing.
Low-Speed Machinery
Its low-frequency response makes the Velomitor CT useful where slower machine vibration must be trended reliably.
Pump Monitoring
The transducer can provide continuous casing-vibration data on pumps with a compatible monitoring system.
Compressor Monitoring
Velocity measurement can be used to trend structural vibration on compressor casings and bearing locations.
Fans and Blowers
The sensor supports general case-vibration monitoring on fan and blower assemblies.
Reliability Trending
A continuous velocity signal allows plant reliability teams to compare vibration changes over time and identify developing machinery problems.

Frequently Asked Questions

1. Can 190501-09-99-01 connect to any vibration monitor?
No. Confirm that the monitor input supports the Velomitor CT sensitivity, excitation and polarity.
2. What can cause 190501-09-99-01 to show inaccurate readings?
Poor mounting, unsuitable cable installation or operation outside specified frequency and vibration limits can affect the signal.
3. Can high-frequency vibration reduce the usable range of 190501-09-99-01?
Yes. High-frequency vibration above the specified limits can significantly reduce the usable range.
4. How far can the 190501-09-99-01 signal be wired?
The datasheet specifies up to 305 m of the stated cable without signal degradation, subject to the documented installation conditions.
5. Why is rigid mounting important for 190501-09-99-01?
A loose or flexible mounting path can introduce motion that does not represent actual machine casing vibration.
6. What should be checked before replacing 190501-09-99-01?
Check the complete suffix, mounting arrangement, cable termination, monitor input and hazardous-area requirements.
