CONNECTED TECHNOLOGY. CLEARLY EXPLAINED.
Vibration sensors
Select vibration sensing through the machine question, measured quantity, frequency range, mounting, signal chain and a qualified maintenance workflow.
Vibration sensing turns mechanical movement at a particular point into a measurement. The result depends on the sensor, mounting, acquisition and processing, as well as the machine’s operating state. Select the complete measurement chain for a defined engineering question before choosing a connected dashboard.
Specify the measurement before the connection
State the machine question
Identify the machine, measurement point, operating condition and maintenance decision. Have the responsible engineer define the useful quantity and frequency content. A general motion detector or an activity sensor is not automatically suitable for the vibration measurement required by a machine investigation.
Define a usable signal range
Record the required axes, measurement range, frequency response, noise and processing method. Keep acceleration, velocity and displacement identified with their units and derivation. A headline sampling rate, maximum range or radio reporting interval alone does not describe the useful vibration information.
Plan a repeatable installation
Choose the measurement location, orientation and permitted mounting through the machine and sensor instructions. Analog Devices’ CN0533 reference guide explains that the mechanical interface affects delivery of vibration to the sensor. Include access, environment and future replacement in the installation record.
Trace the signal from the machine to a reviewed finding
Component, module or complete instrument
Distinguish a sensing component, an evaluation board, a packaged sensor and a supported monitoring system. Each leaves different work for power, housing, acquisition, processing and interpretation. Analog Devices’ ADcmXL1021-1, for example, is a documented single-axis module with processing and an SPI interface, not a ready-made wireless maintenance service.
Mounting and mechanical response
Retain the position, sensitive axis and mounting method with every comparable record. Mechanical coupling and unwanted resonance can affect the result; the CN0533 guide gives a reference-design example. Have the engineering team establish a repeatable installation instead of assuming that any convenient attachment preserves the sensor’s stated response.
Acquisition and useful outputs
Confirm the sampling configuration, filtering, record length and the meaning of any waveform, spectrum or summary statistic. Check whether the selected interface exposes the information needed by the analyst. The ADcmXL1021-1 documentation separates real-time streaming, statistical capture and configurable spectral processing; those capabilities should not be conflated.
Interfaces and connected delivery
Match power, analogue or digital interface, acquisition equipment and configuration to the exact product. Distinguish a locally acquired signal from a feature calculated or uploaded later. Preserve timestamps, units, measurement-point identity and configuration changes through the gateway and platform.
Operating context and comparison
Record relevant machine speed, load, process state and collection conditions alongside the measurement. Define a meaningful reference with the responsible analyst. Keep a missing or invalid observation distinct from a low reading, and review how a sensor replacement or processing change affects comparison with earlier records.
Alerts, investigation and maintenance
Identify who reviews an exception and what corroborating evidence they need before authorising work. Keep unresolved causes and false alerts visible. A threshold crossing or changing spectrum is not, by itself, proof of a particular fault, remaining service life, safety protection or achieved downtime saving.
An illustrative measurement brief
For one authorised machine, list the engineering question, sensor and acquisition identity, mounting, operating state and required outputs. Ask the responsible team how repeatability and a reference measurement will be checked. This is an evaluation brief; no machinery was instrumented and no vibration dataset was collected for this page.
Primary technical examples
Analog Devices: CN0533 evaluation guide explains an example signal interface and mechanical mounting. Analog Devices: ADcmXL1021-1 documentation describes a module’s acquisition and processing functions. These manufacturer examples do not validate a different sensor or a site-specific fault diagnosis.
Connect sensing to a maintenance process
Condition monitoring and maintenance follows interpretation, work orders and feedback. The manufacturing guide places the measurement within an accountable operating workflow. Keep monitoring separate from a protective control system unless separately engineered and approved.
