Air Temperature Sensor

The TA40 & TA60 Series air temperature sensors are high quality electronic sensors designed to measure ambient air temperature. The improved design using high stability components provides faster and more accurate temperature sensing. The temperature stability of the new design allows realistic temperature measurement accuracies of better than ±0.2°C over the entire measurement range.

The sensing element consists of a semi-conductor integrated circuit that provides a linear output voltage proportional to the ambient temperature. The microprocessor reads the voltage and provides a very stable square-wave frequency proportional to the air temperature. For ambient air temperature readings we recommend that the sensors are located inside a louvred radiation screen, to protect from direct and reflected solar radiation and precipitation. This sensor screen should preferably be located at a height of 1.2 to 1.5 metres above ground level. The ideal screen to use is Environdata’s SS31 Sensor Shelter. This modern version of the Stephenson Screen is constructed from aluminium and then powdercoated so it is robust enough for any environment.
