What is and what is used for
The R102 pluviometric sensor measures the precipitation collected by a circular orifice (funnel-shaped) calibrated 1000 cm², supplying a signal for every one-fifth millimetre of fallen water (20 g). The sensitive element is made up of a pair of swinging tanks; the central oscillation pin consists of two stainless steel knives resting on a Teflon support.
The pluviometric sensor, consisting of a collector funnel with a usable surface of 1000 and a pair of swinging tanks, complies with the precision requirements, both low density and high density of rain, of the WMO standards.
- Correction algorithm: since the transit time between the loading position of one tank and the other is not zero, the datalogger with a specific software stratagem compensates the water quantity that continues to fall into the full tank before the other reaches the loading position based on the rainfall intensity. Special mechanical stratagems have also been adopted to increase the transit speed and to reduce the distance between the tank loading positions.
- Easy maintenance: the benefits that our pluviometric sensor offers are not limited to precision, but also include simple and quick maintenance due to the engineering of the sensor that simplifies the phases.
- Sturdy and reliable construction: lastly makes it an instrument with a long lifetime, which safeguards the customer’s investment.
- Components that can be added or be built into the product: for the pluviometres also affected by snowfall, the cylinder has an internal coating that reduces heat exchange between inside and outside; a set of heaters are also activated when the external temperature is lower than 4°C so that the snow dissolves in the water when heated in the funnel.
