Page 13.1106.2 • Develop and demonstrate programs showing how the timer and counter functions are integrated to a PLC • Properly use program control instructions • Properly use math and data manipulation instructions • Describe and use immediate input and output instructions • Interface digital and analog devices to PLCs • Explain the need and process for troubleshooting PLC controlled systems • Prepare students for challenging industrial jobs in the engineering technology areasThe course spends about 70% time in lecture, and about 30% time in laboratory. Studentsare also allowed to use the PLC equipments in their convenience at other times. After thelecture, students practice PLC programming using

the probe is approximately 4 times the diameter of the probe (xh/D = 4). From Figure4, this hole placement produces about a -1% error in the static pressure measurement due toleading edge effects.Pressure Sensor CalibrationEach differential pressure sensor was mounted on a printed circuit board (PCB). The PCB alsocontained the manufacturer recommended power supply decoupling capacitance and reverseconnection protection diode, output signal filtering, and terminal block. Figure 6 shows aschematic of the pressure sensor PCB. Figure 6. Differential pressure sensor PCB schematic diagram.The sensors were then tested by the rocket teams in the laboratory using a column of water as thepressure reference. Figure 7 shows the apparatus

programming was done as a part of senior electricalengineering capstone project at the University of Southern Maine. It has been used in thecharacterization of MEMS Resonator Gas Sensors under different temperature and gascompositions. It is currently being improved by incorporating USB based data acquisition boardsto replace some of the expensive GPIB interfaced instruments to reduce the overall cost of thesystem, and make the system compact and portable. It is the hope of the authors that this systemwill lend itself to be reproduced and adapted for other uses in laboratories and applicationsrequiring an inexpensive and portable means of computer controlled test systems

is 1.30psi. Given this pressure range,we sourced for a pressure sensor available in our laboratory that was functional over asimilar range. A strain gage pressure sensor with a range of 0 – 13psi fit our needs best.This pressure sensor which requires a supply of 13 – 28VDC is internally conditioned togive an output range of 0 – 10 VDC. Page 13.579.2 Fig.2.1: Photo of Pressure Sensor. 1 Although this output range is large enough, the output will subsequently be attached to a signal conditioning circuit to improve the resolution of the sensor
