Maintenance of measurement systems and components

In meteorology, sensors and data loggers form the basis of any reliable assessment. Whether it be wind assessments, yield forecasts, climate studies or grid monitoring: the quality of the data directly determines technical, economic and regulatory decisions.

Ageing, drift and environmental influences

Meteorological sensors are constantly exposed to extreme conditions – UV radiation, temperature fluctuations, humidity, salt, dust and mechanical stress. Even high-quality sensors are therefore subject to a slow drift in their measured values. Without regular maintenance and calibration, systematic errors arise which often go unnoticed but can have a significant impact over months or years.

Economic and regulatory requirements

International standards (e.g. WMO recommendations, IEX standards, QA requirements from assessors and network operators) clearly stipulate that measurement systems must be regularly inspected, tested and calibrated. Maintenance is therefore not a ‘nice-to-have’, but a fundamental component of quality-assured measurement technology.

What Wilmers Messtechnik GmbH can do for you

Wilmers Messtechnik offers the complete maintenance and service chain for meteorological measurement systems – covering all manufacturers and tailored to practical needs.
