BASIC INSTRUMENTATION MEASURING DEVICES AND BASIC PID CONTROL


INTRODUCTION
Instrumentation is the art of measuring the value of some plant parameter,
pressure, flow, level or temperature to name a few and supplying a signal
that is proportional to the measured parameter. The output signals are
standard signal and can then be processed by other equipment to provide
indication, alarms or automatic control. There are a number of standard
signals; however, those most common in a ....etc

Electricity & Magnetism


Atoms

Have neutrons, protons, and electrons.

Protons are positively charged

Electrons are negatively charged

Electrons

Are located on the outer edges of atoms they can be moved.

A concentration of electrons in an atom creates a net negative charge.

Static Electricity

The build up of an electric charge on the surface of an object.

The charge builds up but does not flow.

Static electricity is potential energy. I ....etc

reverse magnetism technical seminar with ppt

The Earth has a magnetic field, as can be seen by using a magnetic compass. It is mainly generated in the very hot molten core of the planet and has probably existed throughout most of the Earth's lifetime. The magnetic field is largely that of a dipole, by which we mean that it has one North pole and one South pole. At these places, a compass needle will point straight down, or up, respectively. It is often described as being similar in nature to the field of a bar (e.g. fridge) magnet. However the ....etc

basic antenna theory ppt

Antenna theory and antenna terminology can seem complicated to the uninitiated. A lot goes into designing antennas but with a little bit of guidance and explanation, antenna users (network designers, systems integrators, end users) can read through the antenna specifications and choose the right antenna style for their wireless network design.

In this paper we will go over some simple techniques to help you better understand some terminologyused and how it is applied in the Antenna industry. This will be part one of a ....etc

Abstract

Magnets have been known for centuries.
The Chinese and Greeks knew about the magical properties of magnets. The ancient Greeks used a stone substance called magnetite. They discovered that the stone always pointed in the same direction. Later, stones of magnetite called lodestones were used in navigation.

William Gilbert, an English physician, first proposed in 1600 that the earth itself is a magnet, and he predicted that the Earth would be found to have magnetic poles.

ABSTRACT

Materials Science research is now entered a new phase where the structure and properties of materials are investigated, characterized and controlled at the nanoscale. Though as sophisticated as their larger counterparts, these devices are still burdened because they rely on an outside power. The size of the entire device is determined by the size of the power source. Batteries and other traditional sources are too large, and tend to negate the size advantages of nano devices. Also, batteries being used at present require toxic ch ....etc

The interface between different fields is believed to be fertile ground for breakthrough research. The interface between the emerging fields of biotechnology and nanotechnology is particularly interesting. The possibilities for new fruit are diverse: biotechnology offers new approaches for self-assembly of structures at the nanoscale, while nanotechnology offers new methods for probing and accessing biological systems. In this talk, I will discuss research in this new frontier in my group, including 1) self-assembly of 2D nanocomponent arrays b ....etc

Nanoelectronics and nanomirror memory
Nanoelectronics refer to the use of nanotechnology on electronic components, especially transistors. .nanoelectronics often refer to transistor devices that are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. hybrid molecular/semiconductor electronics, one dimensional nanotubes/nanowires, or advanced molecular electronics are the present candidates that fall in the nanoelectronic component category. Nanoelectronics holds the promise of making ....etc
