FIELD: thermal and hygrometry. SUBSTANCE: predominant application field of device lies in measurement of parameters of microclimate. In correspondence with first alternative pneumatic device has differential amplifier, non- linear element and two pneumatic resistors. Apart from them device includes air intake element which outlet is linked to inlet of air intake gear. Air intake gear is connected to outlet of first pneumatic resistor, to second inlet of non-linear element and is joined by control conduits to unit computing relationship. First output of unit computing relationship is connected to humidity pressure-to-analog signal, second output is connected to temperature pressure-to-analog signal converter. First and second inputs of unit computing relationship are correspondingly connected to outputs of differential amplifier. Pneumatic device measuring parameters of microclimate includes source of stabilized rarefaction which output is connected to inlets of first and second pneumatic resistors. Second pneumatic resistor is connected to input of adjusting air intake gear and to first input of non-linear element.
