The conception of a multiparameter equipament for evaluation of agricultural machinery cabins

The functions of the cabin on agricultural machinery go beyond protecting against risk overturning and adverse weather conditions, such as wind rain. cabins must also have a shield physical, chemical, biological risks, present in crops. In this context, work aims to design equipment capable measuring atmospheric pressure, incidence ultraviolet radiation from sun, temperature, relative humidity air, inside outside cabins, at same time. methodology used development demanded definition customer requirements, which were converted into requirements. From analysis these, specifications established. To meet formulated specifications, functional structure was defined through synthesis process (operating concept). conception generated by equipment, two modules, cabin, allows performance differential comparative analyzes between parameters environments considered, serving tool for designs safer machines.
