Bently Nevada 330500-02-00 9571-54 Velomitor Velocity Sensor
A rugged two-pin integrating piezo-accelerometer supplied with an M8 × 1 adapter and no hazardous-area approval option.
Product Identification
330500-02-00 is a Velomitor piezo-velocity sensor for absolute bearing-housing, casing and structural vibration measurements. It integrates acceleration internally and provides a velocity-proportional output for machinery condition monitoring.
The ordering suffix selects the M8 × 1 mounting-thread adapter and no agency-approval option. This configuration should be matched to the machine mounting point, monitor input and required field cable before replacement.

- Uses a rugged two-pin construction with an isolated case.
- Supports long cable runs when the specified interconnection method is used.
- Fits rolling-element-bearing machinery where casing velocity is an effective condition indicator.
Applications
- Bearing-housing vibration monitoring
- Machine casing and structural measurements
- Rolling-element-bearing condition monitoring
Lifecycle
- Protect the two-pin connector and M8 adapter during storage.
- Retain baseline vibration and channel-scaling records for future comparison.
- Keep approval requirements separate from the no-approval sensor configuration.
FAQ
What does suffix 02 mean in 330500-02-00?
It selects the M8 × 1 mounting-thread adapter supplied with the sensor.
Does 330500-02-00 carry a hazardous-area approval option?
No. The final 00 code means no agency approval is selected for this configuration.
Can 330500-02-00 replace a moving-coil Seismoprobe directly?
Not without checking the monitor input, bias requirements, sensitivity, frequency response and channel configuration.
Which cable should be ordered with 330500-02-00?
Choose a compatible two-conductor shielded cable with the required connector, length and environmental protection.
What mounting issue most affects 330500-02-00 performance?
A poor or flexible mounting surface can reduce response accuracy and introduce signals that do not represent true machine vibration.
What should be checked after installing 330500-02-00?
Confirm sensor bias, wiring polarity, stable noise level, channel scaling and a baseline comparison at the machine.
