Best fit
Use this guide when a maintenance team needs field sensing and reliable data acquisition for pumps, motors, fans or remote equipment. SunGene supplies the hardware layer and integration-ready measurements; specialist waveform analysis, fault diagnosis and predictive algorithms remain in the customer or selected maintenance platform.

Define the maintenance decision first
Condition monitoring is useful when each measurement supports an action: inspect a bearing, check alignment, investigate overload, confirm cooling or plan a site visit. Start with asset criticality, likely failure modes, operating states and the response expected from each alarm. A list of sensors without an inspection workflow can create data without improving maintenance decisions.
Choose signals that match the failure mode
Vibration can indicate a change in mechanical condition; surface or winding temperature can expose thermal stress; motor current can show load changes; run status and speed provide the operating context needed to interpret those trends. Pressure and flow are also valuable for pumps because a mechanical or process problem may appear in the delivered duty before it appears as a single sensor alarm.
Separate trend monitoring from waveform diagnosis
A low-rate RMS, peak or overall vibration value can support remote trending and threshold alarms. It is not the same as high-rate waveform capture, FFT analysis or bearing-fault diagnosis. Projects requiring spectral diagnosis must define sample rate, bandwidth, synchronous speed, waveform storage and the specialist analysis platform. SunGene does not present a field gateway as a substitute for that diagnostic layer.

FAQ
Is condition monitoring the same as predictive maintenance?
Condition monitoring supplies measurements and alarms about asset condition. Predictive maintenance is the wider maintenance process that may combine those measurements with inspections, history, work orders and analytical models.
Does SunGene provide machine-learning failure prediction?
SunGene focuses on sensors, remote I/O, gateways and integration-ready data. Machine-learning prediction, fault diagnosis and maintenance workflows remain in the customer or selected specialist platform unless separately provided by that platform.
Can a low-rate vibration value replace FFT analysis?
No. Low-rate overall values can support trends and threshold alarms, but waveform and spectral diagnosis require defined sample rate, bandwidth, storage and specialist analysis hardware or software.
Which signals are useful for pump condition monitoring?
A practical scope may combine run and fault state, vibration trend, bearing or casing temperature, motor current, pressure, flow and level. The final list should follow the failure modes and operator actions for that pump station.
What should be included in a quotation request?
Provide asset type and quantity, operating speed and states, target failure modes, required signals, sensor mounting information, cable distances, gateway or platform protocol, network, power, environment, certificates and pilot timeline.
