Bently Nevada 330500-00-02 is a solid-state Velomitor piezo-velocity sensor for measuring absolute vibration of a bearing housing, machine casing or structure. The internal electronics provide a velocity output without moving parts, allowing installation in vertical, horizontal or other orientations when the mounting surface is suitable.
The sensor provides 100 mV/in/s sensitivity, a 4.5 Hz to 5 kHz frequency response and a 50 in/s peak velocity range. Option 00 specifies no mounting-thread adapter and option 02 specifies the ATEX version.
Install the sensor on a rigid prepared surface at a location where rotor vibration is effectively transmitted to the casing. Confirm mounting hardware, cable pinout, channel power, output bias and velocity scaling before enabling protection logic.

Bently Nevada 330500-00-02 measures absolute vibration velocity at a bearing housing, machine casing or structural mounting point and provides a conditioned velocity signal.
Bently Nevada 330500-00-02 provides 100 mV/in/s sensitivity with a documented response from 4.5 Hz to 5 kHz within the specified tolerance.
On Bently Nevada 330500-00-02, option 00 means no mounting-thread adapter is supplied and option 02 identifies the ATEX approval configuration.
Bently Nevada 330500-00-02 requires a compatible powered velocity-sensor input that supports the sensor bias, polarity, 100 mV/in/s scaling and expected frequency range.
Bently Nevada 330500-00-02 should be rigidly mounted on a prepared bearing-housing or casing surface with the approved adapter or stud and secure shielded cabling.
Another Velomitor variant should not directly replace Bently Nevada 330500-00-02 until the sensitivity, connector, adapter, approval, temperature range and monitor input are confirmed.
Provide the Bently Nevada 330500-00-02 nameplate, mounting adapter requirement, connector and cable details, monitor channel, hazardous-area approval, quantity and destination.
Send the complete model, revision, quantity, destination and nameplate photo so the exact hardware identity can be checked.
