t001 SMART
Outdoor Air Temperature Transducer
SMART has been designed for meteorological, hydrological, airport stations, and for all outdoor applications.
The sensitive component of SMART consists of a Pt100 platinum resistance thermometer with response curve compliant with standard DIN 43760 Class 1/3 and 4-wire connection. The sensor body is made of high quality plastic material with stainless steel screws. The sensing element is protected from the external radiation by a special non-hygroscopic screen made of an intrinsically anti-UV plastic material. Moreover, thanks to its curvy-shape in section the internal natural ventilation is improved, ensuring an ideal environment of measure. The sensor can be supplied with natural output (4 wires), or with standardized electrical outputs in voltage, current or digital (Modbus or SDI-12). The sensor is supplied with power and signal cable (4m).

SMarT CELLino
PROFESSIONAL SCREEN FOR HIGH PRECISION THERMOMETERS
The SMarT CELLino professional solar screen is the result of 100 years of experience in achieving the best performances indicated by the WMO (guideline n°8 Annex 1.A) in measuring air temperature, obtained by preserving the sensitive element as much as possible ( thermometer) from interferences (errors) connected to solar radiation, extending the indications of the WMO (direct) also to the components reflected from the ground (soil, snow, sand,…) and diffused ones, and ensuring perfect natural ventilation.
SMarT CELLino offers absolute performance in terms of protection from radiation with regard to Stevenson sheds and also sets itself as a reference in comparison to ventilated screens, guaranteeing adequate air flow to the measurement chamber.
This excellent result, which overcomes the limits of the two aforementioned types of screens, derives from the patented idea of an “S” wing structure of the plates constituting SMarT CELLino which favors the best natural ventilation obtainable even in calm wind conditions (<1 m/s).
SMarT CELLino: the new reference screen for air temperature and humidity measurements.

t002 TTT
Ground Temperature Transducer
TTT is a high-quality temperature sensor that has been manufactured on purpose by Siap+Micros for soil temperature measurement. It is suitable for agrometeorological applications and generally flexible to be used in every environmental monitoring. The sensor is extremely accurate and it is composed of a 30 cm long graduated plastic rod, equipped with a sensing element mounted on the rod edge. By inserting the rod into the ground, TTT can easily provide the value of soil temperature with respect to a specific variable requested deepness. The protective body is made of high-quality plastic. The sensing element is based on a Pt100 Platinum thermo-resistance calibrated with a response curve in accordance with Class 1/3 DIN 43760 standard. Furthermore, thermo-resistance is installed into a stainless steel tube, which protects it from corrosion and ensures at the same time an excellent sensibility to temperature. The sensor is supplied with power and signal cable (12m).

t012 TTS
Surface Temperature Transducer
TTS is a sensor which specifically allows to measure the temperature above the soil, preferably at a height of 10 cm, and it is typically used for agrometeorological monitoring. It is besides very versatile being suitable for many different applications, even in harsh and unfavourable environmental conditions. The sensing element is based on a Pt100 Platinum resistance calibrated with response curve in accordance with Class 1/3 DIN 43760 standard. It has been designed in order to give very reliable performances in the long run, ensuring accurate output data. This sensor is provided with a protective robust screen, which allows to detect the temperature without being influenced by solar radiation. The position of the sensor inside the screen prevents it from being hit by sunlight. The sensor’s body is made of high-quality plastic, the protection shield is made of ABS (a resistant plastic material and non-hygroscopic), and UV stabilized material with low thermal characteristics that ensure long-term stability. The sensor is supplied with power and signal cable (12m).

t020-TTA
Water termperature transducer
The TTA sensor has been designed to collect the water temperature measurement with high precision and reliability. The
sensitive element is a Pt100 thermometer with response curve according to the standard DIN 43760 1/3.
The sensor’s body is made of PVC, a material which ensure to the instrument a reduced weight but an excellent protection and durability at the same time.
The probe is available with different types of electrical outputs: 4-wire Pt100 (-N version), 4-20mA (-I version), 0-2
V (-V version) or serial RS485-Modbus (-S version) .
For the “-I/-V/-S” versions the probe requires a junction box to be installed out of the water for signal conversion.
The sensor is provided along with 15m of power and signal cable (+4m of cable for connection to
the junction box for the “-I/-V/-S” versions).
