Measuring Systems

TPIR measures the global solar radiation, calculated as sum of the direct sun radiation, and the radiation diffused by the sky and scattered clouds. Thanks to its standards of accuracy the sensor is a very suitable device for various applications in the field of meteorology. TPIR is equipped with a thermopile element, specifically designed and developed for SIAP + MICROS. The sensing element generates a tension proportional to the captured radiation, which is acquired by a signal conditioning electronics that normalizes the output in a standard tension, current, Modbus or SDI-12 signal. Performance features are significantly improved thanks to a double dome made of special optical glass (Schott K5), which allows a wide range of solar radiation frequency measurement (0.3 ÷ 3 μm). The production process is fulfilled by a calibration in a climatic chamber with an artificial light source, in order to obtain high accuracy even when the temperature varies. The sensor is supplied with power and signal cable (4m).

TNU-K sensors capture snow level up to either 4 or 10 meters, according to the model in use (TNU04, TNU08). Functioning system is related to the emission of short ultrasonic frequency pulses towards the depth of snow to investigate and to the subsequent reception of the reflected wave, generated once the pulses reach the surface the snow is lying on.
It ensures excellent performance for what concerns accuracy, thanks to a system of self-correction of the level measurement. Indeed, by means of an integrated temperature sensor, it can easily take into account the variation of the sound speed as a value depending on the density of the air.
The on-board electronics calculates the level as a function of the time between the emission of the signal and the reception of pulses. In particular, TNU-K is equipped with an amplification and collection system specifically designed to be implemented on snow level investigations.

TBF is a basic sensor for agrometeorology, typically used to investigate with a very high precision the persistence of water drops above the leaf surface. This indicator is fundamental to measure the residence time of water drops on the leaves, in order to identify phytopathological risks or the leaching of treatments from crops.
TBF sensing element consists of two gilded copper electrical circuits placed on glassonite plates, which are specifically tilted to simulate a real leaf. Once the surface gets wet (for rain, condensation, dew, ice, etc.), the system enters into conduction closing the electrical contact.
Sensor body is overall made of high-quality plastic, but particularly the sensing element is mounted

The TSD Sunshine Duration Sensor measures sunshine status and duration. The WMO (World Meteorological Organization) defines
the sunshine duration as the time during which the direct solar radiation exceeds the level of 120 W/m2. The measuring principle is
based on the use of 16 sensors arranged in such a way that, in the presence of sun, at least one of the photo-detectors is exposed to
sun light directly from the sun (besides the diffusion component).
Those sensors which are not directly illuminated by the sun are used for the measurement of the diffused light that is subtracted from
the measurement of the sensor which sees the sun directly to get direct radiation.
The cylindrical glass protects the sensors and the internal circuits of the instrument from the weather and at the same time provides an
excellent transparency to sunlight. This solution avoids the use of mechanical moving parts and ensures high reliability in the time. The
TSD is available with both RS485-Modbus output and SDI-12 one, and it is also equipped with a heating element separately powered
and galvanically isolated which prevents the formation of condensation on the sensitive elements.
