///Weather Sensors


Pizzi Instruments offers a wide range of instruments for meteorological and environmental monitoring to be integrated into geotechnical and structural monitoring systems.
The sensors are connected to our automatic acquisition units CUM3000 or DAC3000, also used for all other sensors in a system. This makes it possible to correlate structural data with environmental data, parameters for the latter often being at the origin of changes in geological and structural problems.


Each instrument has its own specific application and all instruments have the same purpose: monitoring meteorological and environmental parameters in order to predict significant changes of climate which could cause major problems for work activities, people and structures.
Typical applications for all weather instrumentation are:

  • All types of Dams
  • Rivers
  • Monuments and archaeological sites
  • Landslides
  • Galleries
  • Excavations
  • Mining
  • Other

Features and Benefits

    • Accuracy


  • Measurement speed
  • Long-term repeatability
  • Easy to use
  • Automated Measurements
  • Remote instrumentation management by dedicated control unit and software
  • Instrumentation compliant with ISO9060 standards, and IEC-17025 to WMO

Measuring Principle

Each instrument has its own mode of operation and its own measuring principle, in fact, each sensor measures a different parameter from all other sensors. Their shared purpose is monitoring such parameters in order to anticipate potential changes in weather conditions and monitor their various phases of development.
Optimum management of observations is essential, as these are the first link in the chain, both from a technical and scientific perspective. Observations form the basis for understanding phenomena and for subsequent weather forecasting.
