Unformatted text preview: Background The apparatus shown in Figure 1 for this compressed air experiment has been developed over several years to be compact, safe and convenient for use in the Instrumentation Lab. You should take a few minutes to look over the apparatus which is a good example of custom design. It is self-contained in a Plexiglas enclosure and contains a strain gage pressure transducer, a linear potentiometer, a hand operated air cylinder, a pressure gage, a solenoid operated valve and a manual valve. The most critical portion of the experiment is automated by a LabView program which activates the system and collects data at a high sampling rate. The apparatus is electrically powered by 110 volts AC (from a wall socket). This connects to a DC supply providing 15 volts for the strain gage amplifier as well as approximately 5 volts for the linear potentiometer. Figure 1. Apparatus for the Compression Study 1 of 8...
