Analog sensors and transducers encountered in control systems:

Characteristics and operational considerations including range, accuracy, response time etc. thermal, position, velocity, flow, power, strain, level etc)

Signal conditioning and signal transmission systems:

Noise in transmitted signals, pre-amplification, differential amplification, filtering. Analog control signal standards: 4-20mA, cabling, 3-wire and 4-wire circuits. Nulling, calibration and fault detection on sensor circuits.

Digital Sensors:

Switching characteristics (speed, power rating, sensitivity and reliability of mechanical, electromechanical and electronic sensors. Transistor switches, gates and logic, photo- diodes, opto-couplers and encoders. Analog to digital and digital to analog conversion.


Open loop control of simple actuators using PLCs.

Principles of feedback control:

Benefits and disadvantages. Practical proportional control using standalone PID controllers, PLC, PC or industrial control networks.
