Question: 1
A chemical plant needs a microprocessor-driven alarm system to warn of critical conditions in one of its chemical tanks. The tank has four (HIGH/LOW) switches that monitor:
Temperature (T)
Pressure (P)
Fluid Level (L)
Weight (W)
Design a system that will notify the microprocessor to activate an alarm when any of the following conditions arise:
- High Fluid Level with High Temperature and High Pressure
- Low Fluid Level with High Temperature and High Weight
- Low Fluid Level with Low Temperature and High Pressure
- Low Fluid Level with High Temperature and Low Weight
