ABOUT THE PROJECT

To sense & feed the different proportion of different

raw materials to the any plant.

Also using HMI to set the proportion of feed.

Load sensors which sense the weight of the raw

material in the main hoper.

Temperature will be measured before the material

moves on under the uncertain conditions feed will be

stopped.

APPLICATION OF PROJECT:Since this is an industrial based project and is widely

used in heavy industries where a product is formed by the

mixing of different materials in different proportionalitydepending upon the requirements of the plant and

demands of the consumers.

Delta PLC Siemens PLC

Cost effective as compared to

Siemens.

No need of separate powersupply, CPU, separate input

modules & separate output

modules even analog I/Os isalso in the single package .

User friendly , software is

easily available & easy to

understand.

Much expensive.

In Siemens power supply,CPU, Input cards & outputcards separately each &every thing should bepurchased for ourapplication there would be

again useless I/Os afterpurchasing separate cards.

Complex as compared toDelta often software is notavailable & difficult to use.

DELTA PLC(DVP20EX2T with extension module

DVP16XP211R) It is cost effective.

Programming and usage

of Delta PLC is user

friendly. Easy tounderstand.

It has many built in

functions.

Load cells are often classified by their outershape. Classifications include the can type, the

S type, the washer type, and the beam type.

LOAD CELL WORKING & CALIBRATION W.R.T THEPROJECT

Principle is based on 1mv/v or 2mv/v. In our project the2ndoption is suitable. if the load sensor is of 10V Dc

then maximum output it can produce will be

2x10=20mv

& minimum output will be0x10=0mv

We can now plot the linear graph of the output of the

load cell if the capacity of the load cell is 10Kg let say

then20mv=10kg 16mv=8kg

12mv=6 kg 8mv =4kg

4mv=2kg 0mv=0kg

RTD(PT100) WORKING & CALIBRATION W.R.TTHE PROJECT

RTD changes its resistance as temperature changes.

PT100 has its resistance 100at 0C & 138.4at100Cthe response is approximately linear with respect to

temperature. For PT100 for every 1C change in temperature the

change in resistance is 0.384.

We can plot the graph by using this equation

where Ro=100.

This is the basic IR circuit

design.

We have used two transistors

2222A to operate the relay.


14/17

Gate valves are used to open or

close way of material.

For example: If it uses five

rotation to close/open. We can

count the rotation by IR sensor. We are using DC gear motor to

operate valve and through the

PLC we can manage the

rotation of motor. In this waywe are using this valve.
