Aerodynamic motor amplifier 1 can be used in conjunction with any hans rudolph linear two-way screen aerodynamic motor. These models have eight different calibration flow ranges and are heated and non-heated. Hans rudolph sold separately. For complete information and parts numbers, see table 691037。
Aerodynamic amplifier 1 (pa-1) measures air currents using a differential pressure method. Small pressure differentials occur at the output pressure port of the aerodynamic pump when the gas flows through the pump. These ports are connected through small diameter tubes to pneumotach amplifier 1 flow input port. Pressure differential signals are measured by sensitive +/- 2 cm h2o pressure sensors and amplified to provide simulation output proportional to flow. Linearized circuits can correct the slight non-linearity of the aerodynamic output. By connecting a positive pressure port to the airway and connecting another port to the atmosphere, an additional pressure differential sensor can be provided to measure the pressure in the airway. It can also be used to measure pressure differentials by connecting two sensor ports to different points in the circuit。
Simulation output can be configured into different voltage ranges to simplify connections to data acquisition systems. You can configure the output to a unipolar or bipolar operation within each output range. Modified and gain-adjusted electrons can be used to adjust zero and calibrate。
