Temperature
Soil surface temperature sensor
SST
RTD sensing element 1/3DIN Pt100, with four-wire connection, Pt100 output or electrical signal in current or voltage (4 to 20mA or 0 ÷ 2Vdc), or in digital output on RS485/Modbus (with external interface). The sensing element is protected by a series of screens against direct sunlight and UV radiations, arranged to guarantee a natural ventilation to ground level. Its particular white reflective colour, cancels the warming effect induced on the sensing element, ensuring maximum accuracy.
The sensor is manufactured according to WMO (World Meteorological Organization) standards.
