MOTOR ASPIRATED AIR TEMPERATURE SENSOR DTA 32
Designed to measure ambient air temperature with high accuracy
Dual concentric radiation shield
Low sensitivity to the solar radiation
Motor aspirated
Low voltage motor excitation
Digital status of aspiration
The aspirated air temperature sensor DTA 32 is, due to the motor forced aspiration, much less sensitive to the influence of other meteorological parameters on the measurements of ambient temperature.
However, it requires an auxiliary power to drive the motor. Therefore it is less suitable for the applications, where low power consumption is essential.
Sensing element of DTA 32 is thermolinear thermistor, protected by a stainless steel capsule and mounted on a support, made of thermoisolating material. It is located in the centre of the lower section of the double stainless steel tube. Tube protects the thermistor from being influenced by solar radiation and precipitation, or mechanically damaged.
