one of the main difference between sensor and transducer is that a

transducer is a device that can convert energy from one form to another whereas

a sensor is a device that can detect a physical quantity and convert the data

into an electrical signal sensors are also a type of transducer in this video

I will be going to show you difference between sensor and transducer firstly we

see definition of sensor the sensor is a device that measures the physical

quantity that is heat light sound etc into an easily readable signal that is

voltage current etc it gives accurate readings after calibration definition of

transducer transducers are often employed at the boundaries of automation

measurement and control systems where electrical signals are converted to and

from other physical quantities that is energy force talk light motion position

etc the process of converting one form of energy to another is known as

transduction now we see the difference between sensor and transducer are

explained below in the comparison chart sensor which converts one physical

quantity into electrical quantity transducer which converts one form of

energy into another foam sensor just sends the physical quantity it does not

convert to any foam transducer equal sensor plus transduction element it

converts one form of energy into another form sensor which can respond to a

change in physical parameter and produce a change in a physical parameter that

can be sensed transducer which convert a change in physical parameter into some

useful energies form sensor is nothing but just a primary element which senses

any physical phenomena or it gives an indication in any change of the physical

phenomena every transducer is always having a sensor but every sensor doesn't

need to be a transducer sensor output is always

trick output transducer output always will not be an electric output a sensor

is the complete assembly required to detect and communicate a particular

event a transducer is the element within that assembly which accomplishes only

the detection of the event proximity sensor magnetic sensor accelerometer

barometer are the examples of the sensors the thermistor and thermocouple

is the examples of the transducer dear viewers thanks for watching the video if

Difference between Leader and Leadership - Duration: 2:44.

We are involved in many groups: at work, at school, at home.

Some of these groups are effective while others…not so much.

Those that are ineffective may be lacking leadership.

If you've ever read Scott Adams' comic strip, Dilbert, you know what I mean.

But, then, what is "leadership?"

That's what this video will focus on: The difference between a leader and leadership,

American author, John C. Maxwell, noted that "Leadership is influence."

Notice that he didn't classify "leadership" as a person, but more of a process.

That's the primary difference between a leader and leadership.

A leader is an individual—a person—who is perceived by the members of his or her

group as having a legitimate position of power or influence in the group.

This individual could be assigned as a leader or delegated to the position.

Or even could emerge from the group, formally or informally.

Think of a jury where they end up electing a jury foreman—someone to speak for them.

In contrast, leadership, as former chairman of Westinghouse Broadcasting Company Donald

H. McGannon suggests, a matter of "action, not position."

He claims that we often confuse leadership and authority.

Someone could have authority—be a designated leader, like your manager or the pointy-haired

boss in the Dilbert comic—but may not exhibit leadership behavior.

Leadership, then, can be defined as the process of influencing a group to help it reach its goals.

This involves addressing both the task dimension—what needs to get done—and the social dimension—the

relationships among the people in the group.

A leader, then, can use leadership to influence a group—meeting Maxwell's definition.

But it also means that a leader may merely fill the requirements to manage a group—performing

tasks but not really leading or influencing.

Further, this definition of leadership as a process of influencing others to meet their

goals means that leadership can involve more than one individual.

In fact, it can involve ALL members in a group.

That's where the term, "teamwork," emerges.

So, while you may not be a designated leader, you may still be involved in influencing the

group to meet its goals, meaning that you are involved in the leadership process.

Realize that most employers are looking for people who exhibit leadership skills, so it's

worth your time and effort to develop those skills, even though you may not currently

be a leader.

So, if you exhibit leadership skills as a lower-level employee, it may not be long before

your employer recognizes your leadership potential and you can climb the leadership ladder.

You can not only be a leader in name but also a leader in influence.

What's the Difference Between Pressure Class and Thickness Class Pipe? - Duration: 4:59.

Welcome to Iron Strong. In this video I'm going to address four topics. First, what

is the difference between thickness class and pressure class?

Second, what class pipe should you specify.

Third, how you can use the McWane Pocket Engineer

to determine the pipe class needed for your given project.

And forth, how does McWane manufacture a specific class of pipe.

So what is the difference between thickness class and pressure class pipe?

The short answer to that question is that both refer to a specific wall thickness.

The iron content is exactly the same.

In 1965 ductile iron pipe was introduced replacing its grey

or cast iron predecessor.

Thickness classes 1 through 6 were

standardized and used as a basis for manufacturing and ordering material.

Due to the inherent strength of ductile manufacturers soon realized they could

make a thinner wall and introduce a class zero. However many in the industry

questioned whether a class zero would be accepted by end users.

Therefore the number five was added to the beginning of the thickness class

designation and then you have the thickness classes that you see today.

In 1991 the pressure class ratings were introduced for two reasons first most of

the water and wastewater materials were specified this way, and second by

manufacturing a third wall pipe end users were able to realize a cost

should savings by utilizing materials specific to their needs.

What class pipes should you specify?

Each year McWane Ductile gives presentations at tradeshows, lunch

and learns, or day of water events. When discussing pipe design we often ask

what's what class pipe do you specify? As you might expect we get answers such as

class 350, or class 52 but what's interesting is our follow-up question of why?

This is where we start getting some odd looks and people get nervous to answer.

But eventually someone will speak up and give an answer like that's just the

way it's always been, or that's what's always worked for us.

If tradition sets your specification requirements and you're comfortable with

"the way it's always been" it's not our position to change that specification.

There's nothing wrong with the peace of mind that comes from historical success

and no product performs over the long haul like ductile iron. However if you

really want to answer the question of why you must consider two variables.

First internal pressure which is the amount of pressure exerted by the fluid

inside the pipe. Second external loading which is the amount of force exerted by

backfill, traffic, buildings, anything above the pipe.

So they're formulas that you can use to determine the pipe wall thickness required for your specific need.

However McWane's made it easy by

offering the use of the McWane Pocket Engineer free of charge. Simply download

the app or use the web platform.

The pocket engineer allows you to input the

known design variables such as pipe diameter, maximum internal pressure, depth

of cover, wheel load, and the weight of the soil used for backfill.

At the click of a button you'll be able to determine what class and correlating

wall thickness you should require for all five

AWWA a recognized trench types. there's two factors that control the wall

There's 2 factors that control the wall thickness that we manufacture.

First is the ladle size, and second is machine travel time.

For every pipe size and class there's a corresponding ladle that's utilized.

Ladles are found on the iron delivery end of the machine.

They're used to pour the liquid iron down a trough into the spinning mold.

As you can see each casting machine is set up on an incline or hill.

As the melted iron moves through the machine from the top of the hill the machine moves down the hill to

disperse the iron throughout the mold. The time it takes the machine to move

down the hill is what we refer to as machine travel time.

By controlling the speed at which the machine travels down the hill along with the speed and which

the iron is being poured from the ladle we can maintain

a specified wall thickness throughout the pipe barrel. If you'd like more

information on what you've just viewed what would be interested in McWane

presenting to your group please contact your local sales representative and they

would be happy to assist.
