        Overview Manuals Measurement Mounting Signal Path Product Applications

        Features:

        • The solid-state piezo-velocity design supplies a direct housing-velocity signal without moving sensor parts.
        • The 00 configuration leaves the mounting adaptor open to the actual machine interface rather than assuming a supplied thread.
        • The 02 configuration identifies the European ATEX ordering option for an approval-sensitive procurement.
        330500-00-02 is intended for absolute vibration at bearing housings, casings and suitable structures; the mounting location matters because rotor motion has to reach that surface.

        Its integrated electronics convert the piezoelectric response into a velocity signal, supporting a monitor channel that is configured for that measurement type.

        The complete order code distinguishes both the mechanical-adaptor choice and agency-approval selection, so a family-name match alone does not establish the supplied configuration.

        Apter Power supports documentation review and sourcing for the Bently Nevada 330500-00-02 Velomitor Piezo-velocity Sensor.
        Bently Nevada 330500-00-02 Velomitor Piezo-velocity Sensor Manuals,Datasheets,Link
        Important Notice: Match the exact mounting and approval options to the installed measurement point using Baker Hughes documentation.
        • Integrated piezoelectric electronics deliver a velocity signal directly, so the monitoring input needs a velocity-sensor scale rather than a raw accelerometer scale.
        • The published 4.5 Hz–5 kHz, ±3 dB response defines the frequency band that can be used for a broad machine-vibration review.
        • The ±2% linearity statement stops at 152 mm/s peak even though the maximum stated velocity range is 1270 mm/s peak; these are different selection limits.
        • Transverse sensitivity below 5% helps distinguish motion along the sensing axis from cross-axis response when interpreting a trend.
        • The 00 configuration is supplied without a mounting adaptor, leaving the thread interface to the selected installation kit.
        • Because the sensing assembly has no moving parts, horizontal and vertical orientations are both available when the machine surface is suitable.
        • The 25.3 mm diameter and 63.2 mm body height define the space needed around the measurement point, separate from packaging dimensions.
        • A 316L stainless-steel case supports installation on the selected bearing housing or casing, while contact quality remains a separate mounting issue.
        • The hermetically sealed 2-pin MIL-C-5015 connection determines the mating end of the sensor cable.
        • The published bias of −12 ±3 VDC at Pin A gives the monitoring team a defined electrical reference for this sensor family.
        • Case isolation is part of the specified sensor construction and matters when electrical noise at the mounting surface is being assessed.
        • With 02173006 cable, Baker Hughes specifies a 305 m maximum run; its shorter 63 m recommendation applies under the stated high-vibration, high-frequency and cable-capacitance conditions.
        • Monitor bearing-housing vibration on machinery with rolling-element bearings.
        • Measure casing vibration where motion from the rotor reaches the housing surface.
        • Measure structural vibration in a suitable machine-mounted monitoring arrangement.
        • Use velocity-unit measurements when that signal is the useful condition-monitoring variable.
        Description
        330500-00-02 is a Bently Nevada Velomitor piezo-velocity sensor. Baker Hughes identifies the 00 option as no mounting adaptor and the 02 option as the European ATEX ordering selection; the instrument measures absolute vibration on a suitable machine casing or bearing housing.

        The official 330500 datasheet describes a solid-state design with no moving parts and permits vertical, horizontal or other mounting orientations. Its published typical physical dimensions are 63.2 mm high by 25.3 mm diameter, with a typical weight of 142 g.

        For 330500-00-02 sourcing, retain the complete suffix code and review the OEM sensor, connector and mounting documentation against the installed measurement chain. The ordering option does not by itself establish permission for a particular hazardous-area installation.
        Alternative Names
        330500 00 02 3305000002 330500/00/02 330500-0-02
        Technical notes
        The 330500-00-02 provides a velocity signal, but integrating that output to obtain displacement can amplify electrical noise from interference and the transducer circuit. This may reduce the usefulness of calculated displacement even when the velocity channel appears stable. For a displacement-dependent protection task, the measurement method and noise performance deserve a separate engineering review before adoption.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Our existing 21128 housing will stay in place. Which cable should accompany 330500-00-02?
        For that housing arrangement, Baker Hughes specifies the 89477 interconnect cable to reach the monitor. We can help match its length and connector arrangement before shipment, so the replacement arrives with a complete signal path.
        We need temporary casing readings before choosing a permanent stud. Can 330500-00-02 go straight onto the magnetic base?
        The 46000-01 magnetic base is used with a separate 1/4-28 UNF adaptor, and the 00 sensor option supplies no adaptor. We can help assemble the matching temporary kit before the site visit.
        The available pad on our motor casing is about 20 mm across. Is it ready for 330500-00-02?
        Not yet: Baker Hughes calls for a flat mounting surface at least 32 mm in diameter. We recommend having the pad prepared or an alternative point assessed, since a smaller contact area can compromise measurement quality.
        The monitor OK light went out after we fitted 330500-00-02. Does that mean another sensor is needed?
        Not necessarily. The OEM troubleshooting sequence also considers monitor power, interconnects and sensor bias. We can help the monitoring team identify the installed cable and monitor arrangement before it decides which component to replace.
        The monitor still reports OK, but the vibration channel is flat after installing 330500-00-02. Where should we look?
        A healthy OK indication does not rule out a field-wiring fault. Baker Hughes lists reversed A/B wiring among possible causes of a flat signal; a qualified technician can compare the monitor-end connections with the OEM guide before condemning the sensor.
        The 330500-00-02 channel reads unusually low and shows broadband noise. Has machine vibration really fallen?
        That pattern can reflect signal isolation or connector contamination rather than lower machine motion. The OEM guide identifies those as diagnostic possibilities, so the monitoring team should resolve the signal-path fault before relying on the trend for a maintenance decision.
