Digital control and Industrial Networking

Good afternoon Friends,

As I said before there are some important ( Very Important !!) subjects for Instrumentation and Control Engineer. If you are planning to go for core companies like petrochemical, pharmaceutical, chemical, oil and gas etc. then knowledge of these subjects beneficial to you. These subjects are

1. Process control and instrumentation
2. Transducers and measurement
3. Digital control and Industrial Networking
4. Instrumentation systems ......etc

I am posting here some materials related to data networking... please click on below link for download.

Hope you enjoy.....................

Temperature Transducers

A) Expansion Thermometers

1. Expansion of solids - Bimetal thermometers
2. Expansion of Liquids - Liquid in glass thermometers and Liquid in metal thermometers
3. Expansion of gases - Gas thermometers

B) FILLED SYSTEM THERMOMETERS (pressure spring thermometers)

1. Gas filled thermometers
2. Liquid filled thermometers
3. Vapor -pressure thermometers

C) Electrical Temperature Sensors

1. Resistance Temperature Detectors (RTD)
2. Thermistor
3. Thermocouples

D) Radiation Temperature sensors

1. Radiation Pyrometry
2. Optical  Pyrometry

Temperature Units and its conversion

Temperature Units:-

1. Kelvin
2. Centigrade
3. Fahrenheit
4. RANKINE
5. REAUMUR

Above table shows Steam point and ice point of water for different Temperature Units.

UNIT CONVERSION

Generally kelvin scale referred to as a absolute centigrade scale and RANKINE scale referred to as absolute Fahrenheit Scale. ....

Amazing things coming soon...enjoy reading😊

Tranducers and measurement

What is measurement??

It is the act or a result of a quantitative comparison between a predetermined standard and an unknown magnitude.

As a Instrumentation and Control Engineer we are generally dealing with four types of measurement.

1) Temperature measurement

2) flow measurement

3) pressure measurement

4) Level measurement

What is Temperature ?? 

Temperature is a degree of hotness or coldness or in simple words it is a degree of heat.

There are three ways to transfer heat according to thermodynamics
1) conduction:- which only takes place between two solids
2) convection :- from surface to moving fluid
3) Radiation :- between two surfaces which emits radiation.

effects of this heat transfer
1) it changes body's physical or chemical state
2) change in physical dimension
3) change in electrical properties
4) generation of EMF ( electromotive force ) at the junction of two dissimilar metals
5) change in intensity of emitted radiation

for temperature measurements we are dealing with different sensors and transducers based on this five effects.

about different sensors and transducers I post soon..

till that enjoy Reading....!!😊

Here first..

Below link Gives information about pressure sensors. The link only contains Images of pressure sensors. The relevant document I will post you soon.
