Introduction

The hans rudolph 1120 flow simulator, the 1120 pulmonary pulmonary pivot speculation generator, is an electric-driven piston pump that can be used to detect lung function products and other breathing equipment. It was designed for use in product development and manufacturing testing applications. There are three working models for flow/volume simulators. The pneumatic waveform model is used for the use of ats waveforms, peak flow waveforms or custom waveforms to test lung mass meters. Steady flow patterns can be used to generate steady flow within large flows. This model can be used for the testing and calibration of flow meters. Respiratory wave-form patterns can be used to generate a continuous inhalation/exhale waveform for simulated breathing. All modes provide graphics of flow and pressure signals. Data collected during the testing process can be stored in a document for additional analysis。

Internal pressure sensors measure air pressure and cylinder pressure during testing. Pressure data are used to correct the calculated flow of gas compression. Another differential sensor is used to connect pressure water taps on or near the equipment being measured. This pressure reading can be used to determine the movement resistance of the equipment detected. An optional hans rudolph company. Gas cutting can connect to the export of flow/volume simulators. It provides a pressure sensor to measure

The pressure differential on the aerodynamics so that the measured flow signals can also be mapped and recorded。
Two graphics are used to display the collected flow and pressure data. Flow maps can show the flow calculated from the piston position, the flow measured from the gas pump and the target flow calculated from the required wave shape. Pressure maps can show cylinder pressure and auxiliary pressure signals. Both graphics can be dynamically scaled and moved to allow users to zoom in and see specific parts of the waveform or to see the complete waveform. You can print out a graphic。

Lung measurement test
In pneumatic waveform mode, flow/volume simulator will generate all ats waveforms used to test lung function products. You can create a custom wave shape using the practical program provided. Waves can be scaled up or reduced to adjust the waveforms of different flows and capacities. Different pistons allow you to change internal volume。
Peak flow gauge test
A waveform for testing peak flow meters as defined in en13826 can be produced. The simulator was tested by the german federal technical commission (ptb)。

Certification was obtained in berlin for testing peak flow meters. Ptb is the german national measurement agency providing scientific and technical services。

Steady movement
Normal flows can be used to verify the calibration of flow meters, or to provide constant flow for the calibration of flow meters. The volume of the transport can be adjusted to 8. 5 litres. The required flow can be set at 0. 1 to 16 litres per second. You can choose the direction of inhaling or exhale. Pressure and flow data collected during the test are shown on the map after the test。

Breathe
The available applications can be used to create a respiratory waveform, which can then be used to create a simulated respiratory flow pattern. The amplitude and breathing ratio are adjustable, so you can simulate different waves of breath and the same file. Respiratory waveforms can run or repeat over and over again。

Options and accessories
Custom changes can be made to flow/roll emulators. Contact hans rudolph, inc. For information on customised systems。
Basic component 113266 does not include pcs for flow/quantity simulator operations. A computer with usb port and windows 2000/xp operating system are required. You can select the computer to install the software。
Other options include non-heated gaskets for measuring export flows. The pressure sensors needed to convert the pressure differential to flow are included in the base system. A heated lung knife also provides an option. If a wetting system is used, it is recommended to use a heating gasket. If the pneumotach option for heating is ordered, the heater control is added to the flow/volume simulator。
The heating air option can be added to the flow/volume simulator to heat the air in the cylinder. This can be used to increase air temperatures to simulate actual exhale air temperatures。
Pulmonary activity tests can be performed with additional wetting systems for inhaled air to better simulate actual exhaled air conditions. If you order the wetter option, you must also order the heating air option。
