Routine Sensor Inspection and Care
Guidance on routine sensor checks, basic care, and how to maintain reliable operation
Why is routine inspection important?
Sensors are exposed to the environment and, over time, may be affected by weather, salt, dirt, vibration, or nearby work activities. Without routine inspection, small issues can develop into larger problems that affect system performance.
Regular inspection helps ensure that sensors continue to operate within specified parameters and that issues are identified and addressed before they affect system performance or data accuracy.
What should be checked regularly?
As part of normal operation, visually inspect sensors and associated equipment (e.g. mounting brackets, cable connections, and housings).
This includes checking for visible damage, loose components, or signs of environmental exposure. Any warning indicators, alarms, or abnormal readings should be noted and investigated.
Inspect sensors installed outdoors or in exposed locations more frequently — particularly after severe weather events or maintenance activities in the vicinity. If a recommended inspection schedule is provided in your sensor documentation, follow that schedule as a minimum.
Environmental Effects and Work Activities
Work activities such as painting, welding, grinding, or cleaning in the vicinity of sensors can affect their performance. Dust, paint, salt, or residue may accumulate on sensor surfaces and interfere with measurements.
When work is carried out near sensors, protect them appropriately — for example, by covering optical surfaces and sealing exposed connectors. After the work is complete, inspect sensors to confirm they are clean and undamaged.
How should you clean sensors?
Certain sensors — particularly optical sensors such as visibility meters and cloud height sensors, and sensors deployed in exposed or marine locations — require periodic cleaning to maintain measurement accuracy.
Cleaning should only be carried out in accordance with the relevant sensor documentation. Inappropriate cleaning methods or materials can damage sensors and affect performance.
If there is uncertainty about how or when to clean a sensor, WISE Group should be contacted for guidance.
Underwater and Fouling-Prone Sensors
Sensors exposed to water or marine environments may be subject to fouling over time. Fouling can occur more quickly in warm or tropical environments and may affect sensor readings if not addressed.
Regular inspection and cleaning, as described in the applicable sensor documentation, are essential to maintain reliable operation.
When should you contact WISE Group support?
WISE Group should be contacted if:
-
Sensor alarms or warnings persist
-
Sensor readings appear incorrect or unstable
-
Physical damage is observed
-
Cleaning or inspection does not resolve the issue
When contacting support, provide a clear description of the issue, the sensor location, and any relevant readings or alarms. This will help WISE Group respond quickly and effectively.
What are the warranty and maintenance considerations?
Routine inspection and proper care form part of the normal operation of the system.
Failure to inspect, maintain, or protect sensors may affect system reliability and, in some cases, warranty coverage or third-party certification requirements.
What are the key requirements for sensor care?
Routine sensor inspection and care are essential activities that support reliable system performance, accurate data output, and long-term system integrity.
Regular checks, proper protection during nearby work, and timely action when issues are identified will significantly reduce the risk of avoidable problems. Following the guidance in this article also supports compliance with applicable warranty and third-party certification requirements. If you need further assistance, contact WISE Group support.
