Product Introduction
RTD sensing element 1/3DIN Pt100, connection with a four-wire, Pt100 output or electrical signal in current or voltage (4 to 20mA or 0 ÷ 2Vdc) or in digital output on RS485/Modbus. The sensing element is protected by a series of screens against direct sunlight and UV radiation, so arranged to garantee a natural ventilation. Their particular white reflective color, cancels the warming effect induced on the sensing element, ensuring maximum accuracy. The sensor is manufactured according to standard WMO (World Meteorological Organization) and is also available in versions with forced ventilation (code. TAV).
