Strain Gauge Pressure Sensor Principle
Strain Gauge Pressure Sensor Principle : When a closed container is subjected to the appilied pressure, it is strained (that
Types of Control Systems
There are two types of control systems namely: Open loop control systems (non-feedback control systems) Closed loop control systems (feedback
Example of Feedback System
Home furnace control system must control the temperature in the room and kept it constant. As in open loop system
