Atmospherical Precipitation

t043 TP500/TP1000

Precipitation transducer, collecting area 500/1000 cm²

TP rain gauges are very performant and reliable sensors for the measurement of both rainfall intensity and amount. The measuring principle is based on a tipping bucket mechanism, thoroughly designed in order to achieve very high standards of accuracy in the whole range, minimizing friction during the oscillating action of the bucket. The TP is available in the version with impulse/reed contact output only (TP500-N and TP1000-N) and in the version equipped with electronic correction system (TP500-E and TP1000-E) to compensate the error caused by the tilting-pan measurement technology, ensuring high levels of performance even when heavy rainfalls occur. A further version (TP500-12 and TP1000-12) with electronic correction is available with a difference in the serial output protocol: SDI-12 instead of Modbus. The body is made of aluminium alloy and painted with a special anti-UV paint which ensures long-lasting quality and resistance to the weather events. All available models are supplied with power and signal cable (12m).

t027 TP200

Precipitation transducer, collecting area 200 cm²

TP200 is a tipping bucket rain gauge with a collecting area of 200 cm². It is extremely precise, very performant and suitable also for environments where heavy rainfalls easily occur (monsoon or tropical rains). The tipping bucket consists of a v-shaped element, particularly designed to minimize friction and facilitate the oscillating action of the bucket, ensuring high standards of accuracy. The body is made of aluminium alloy and painted with a special anti-UV paint which ensures long-lasting quality and resistance to the weather events. The TP200 can be supplied in three different versions: TP200-N with impulse/reed contact output, TP200-E and TP200- 12, both equipped with a specific signal conditioning electronics that reduces measurement uncertainties at high intensities of precipitation (both for intensity and amount values). TP200-E version equipped with electronic correction can give on a single connector the reed contact output (rainfall amount), the current output (intensity) and the Modbus serial output (both intensity and amount). TP200-12 version is similar to the TP200-E but it has been designed on purpose to have the SDI-12 standard communication protocol instead of Modbus. TP200-N is also available on heated version, powered at 24V (alternating or direct current). In every version, the sensor is supplied with power and signal cable (12m).

t041-TPW

Weighing rain and snow gauge

The TPW series weighing gauge is designed to measure different types of atmospheric precipitation by measuring the weight of the precipitation itself. Whether it is rain, snow, or mixed, it precisely measures the precipitation weight defining both its amount and intesity. The weighing system is protected by an enclosure in order to make the measurement not be influenced by the external environment. Furthermore, the integrated circuit board of the instrument can manage both self-diagnostic operations and processing for the correction of measurement errors due to vibrations caused by wind, dust in the air, temperature fluctuations and other parameters.

t041-TPWE

Self-Emptying precipitation gauge

The TPWE series weighing gauge is designed to measure different types of atmospheric precipitation by measuring the weight of the precipitation itself. Whether it is rain, snow, or mixed, it precisely measures the precipitation weight defining both its amount and intensity. The TPWE is equipped with a special self-emptying mechanism making possible measurement of precipitation which is not limited by the bucket capacity. Once the bucket is almost full it tips and the water flows out through the outlet in the base plate. The emptying occurs fully automatically thanks to the special shape of the bucket. The process is very quick (less than one second) and therefore it doesn’t affect the measurement.
