Temperature Control System

Temperature Control System: Before going to study the temperature control system, let us see the block diagram of microprocessor based process Temperature Control System. It is capable of controlling more than one physical parameter. Such systems are commonly known as data acquisition and control systems. In these system, analog signals from various sensors are converted […]

Sensors and Transducers

Sensors and Transducers: The definition of┬áSensors and Transducers are follows, The input quantity for most instrumentation systems is nonelectrical. In order to use electrical methods and techniques for measurement, the nonelectrical quantity is converted into a proportional electrical signal by a device called “transducer”. Actually, electrical transducer consists of two parts which are very closely […]

Analog Interfacing

Analog Interfacing: Analog Interfacing – The primary objective of industrial process control is to control physical parameters such as temperature, pressure, flow rate, level, force, light intensity, and so on. The process control system is designed to maintain these parameters near some desired specific value. As these parameters can change either spontaneously or because of […]

Interfacing Dip Switch

Interfacing Dip Switch: A series of tiny switches built into circuit board and the housing for which has a same shape as chip are known as DIP switches. The Fig. 15.23 shows the Interfacing Dip Switch housing with 11 switches. DIP switches enable you to configure a circuit board for a particular type of computer […]

Optical Motor Shaft Encoders

Optical Motor Shaft Encoders: The Optical Motor Shaft Encoders are used to get the information about the position, direction of rotation, and speed of rotation of various motor shafts. They provide this information in digital form which can easily be used by microcomputers to control the speed, direction of rotation and position of the motor […]
