![]() ![]() By using DSA-VI, the value of at the transient response can be evaluated. The testing at the settling and surrounding temperatures (T sp and T 0) are 40 oC and 28.81 oC respectively, obtained value of is 7.49 s at T sp and T 0 are 50 oC and 29.88 oC respectively, obtained value of is 11.35 s and at T sp and T 0 are 60 oC and 28.81 oC respectively, obtained value of is 19.54 s. By assuming that an airflow temperature control system as the first order system, the time constant () should be inspected as one of the system characteristics. To investigate the performance of DSA-VI, an experiment has performed to monitoring and control airflow at settling temperature, 40 oC, 50 oC, and 60 oC, respectively by using the DSA-VI. Here, the DSA-VI has developed by using LabVIEW software and Arduino UNO. This work aims to present a Dynamic Signal Analyzer Virtual Instrument (DSA-VI) for monitoring and control the airflow temperature in a prototype of air duct.
