What does the -04 mounting option specify on 330500-04-00?

It specifies a 1/4-20 UNC mounting-thread adaptor.

What does the final -00 code indicate for 330500-04-00?

The official ordering table identifies -00 as agency approval not required.

What physical quantity does 330500-04-00 measure?

It measures absolute vibration of a bearing housing, machine casing or structural mounting point.

Can 330500-04-00 be installed in different orientations?

The sensor can be mounted vertically, horizontally or at another suitable angle when the mounting surface and signal direction are engineered correctly.

What connector is used by 330500-04-00?

The datasheet specifies a hermetically sealed 2-pin MIL-C-5015 connector.

Why is mounting quality important for 330500-04-00?

Poor mounting can reduce amplitude and frequency response or create signals that do not represent machine vibration.

How should polarity be verified on 330500-04-00?

When case motion is toward the connector, Pin A should become positive relative to Pin B.

What should be checked after replacing 330500-04-00?

Verify mounting torque, cable condition, case isolation, channel bias and the measured response against a baseline.

Information

Overview Manuals Common Applications Product Precautions

This sensor configuration converts casing or bearing-housing motion into a conditioned velocity signal for continuous machinery-condition assessment.

Measures absolute vibration at the machine housing or structural mounting point
Uses solid-state integrated electronics with no moving sensing parts
Permits vertical, horizontal or other approved mounting orientation
Provides a case-isolated dynamic velocity signal for monitoring

Mount 330500-04-00 firmly on the bearing housing or machine casing using the supplied 1/4-20 UNC adaptor and the documented torque range. Confirm cable loading, case isolation and signal polarity before accepting the vibration channel.

Important Notice: Confirm the complete 330500-04-00 code, 1/4-20 UNC adaptor, mounting surface, torque, 2-pin connector, case isolation, polarity, cable loading, monitor input and controlled vibration response before commissioning.

Apter Power 330500-04-00 Manuals and Guides

The first document is a model-specific engineering data reference. The second is a distinct installation and commissioning workbook with field checks and acceptance records.

Bearing-housing vibration protection

Measures transmitted casing vibration where rotor motion reaches the bearing housing.

Machine-casing condition trending

Supplies a velocity signal for detecting changes associated with imbalance or misalignment.

Structural vibration assessment

Supports measurement on a rigid structural point selected for meaningful machine response.

Generator stator-frame monitoring

Can support documented Velomitor measurements on generator frame or core structures.

Read the applicable Bently Nevada installation information before work. Verify 330500-04-00 and the installed Velomitor Piezo-velocity Sensor configuration before isolation, wiring or commissioning.

Confirm the full 330500-04-00 order code and 1/4-20 UNC adaptor.

De-energize the monitoring input before connecting or removing the sensor cable.

Prepare a clean, flat and rigid mounting surface on the housing or casing.

Tighten the mounting interface within the documented torque range.

Keep the case-isolated wiring arrangement intact and avoid ground loops.

Verify Pin A and Pin B polarity before channel configuration.

Check cable length and input compatibility with the selected monitor.

Compare the restored vibration response with a controlled reference or known baseline.
