How to Choose a Structural Health Monitoring System

A practical selection guide covering monitoring objectives, sensors, DAQ, communication, software, alarms, reports, and project evidence.

Short answer

Choose a structural health monitoring system by defining the engineering decision first, then matching measurement points, sensors, acquisition channels, sampling behavior, synchronization, communication, software outputs, alarm review, and maintenance requirements. A credible proposal should describe the complete data chain rather than listing instruments in isolation.

Start with the engineering decision

The first question is not which sensor to buy. It is what condition, change, or event the owner must detect and what action the resulting data should support.

Examples include long-term deformation review, vibration-event recording, construction-stage control, cable-force tracking, abnormal trend detection, and post-event engineering assessment.

Define the complete system scope

Asset and structural components to be monitored

Measurement quantities and expected ranges

Measurement point count, direction, mounting, and environmental exposure

Static, dynamic, event-triggered, or mixed acquisition

Required channel synchronization and timing reference

Local, wired, wireless, cellular, or mixed communication

Dashboard, waveform, trend, alarm, report, and export requirements

Commissioning, calibration, maintenance, and engineering review responsibilities

Evaluate suppliers at system level

Evaluation areaEvidence to request
Measurement layerSensor compatibility, range, direction, mounting, calibration, and environmental suitability
Acquisition layerChannel type, sampling behavior, resolution, synchronization, trigger logic, and storage
Communication layerTopology, coverage, power, buffering, retry behavior, and offline operation
Software layerLive data, trends, waveforms, alarms, exports, reports, permissions, and audit history
Engineering layerPoint layout, threshold basis, commissioning records, and review workflow
Project proofRelevant deployment scope, products used, outputs, limitations, and verifiable results

Frequently asked questions

What information is needed before requesting a structural monitoring quotation?

Provide the asset type, monitoring objective, drawings or dimensions, measurement quantities, approximate point count, expected event or trend, communication conditions, power availability, software outputs, alarm expectations, and project schedule.

Should products be selected before the monitoring plan?

Usually no. The measurement plan and required data outputs should define the sensor, DAQ, communication, and software requirements.

Can one system combine static and dynamic monitoring?

Yes, but static trend channels and high-rate dynamic channels may require different sensors, acquisition behavior, storage, and review workflows.
