The Advantages and Different Types of Floor Scales

Any object has a volume and measures some weight. We use to weigh different objects for many purposes. Men weigh himself regularly as he watches his diet and makes sure that he is always healthy. It is also important to weigh passengers and make sure that a boat, plane or automobile is not overloaded. Otherwise it may cause fatal accidents if the transportation breaks down.

Accurate measurements are very important in our day to day activities. It is crucial to manufacturing and many other industrial companies. There are many devices used to measure weight and one of them is floor scales.

This is usually laid on the floor of the home or companies and industries. It is used mainly to weigh heavy objects. You will typically see it in hospitals to get the weight of patients. It is also seen in courier companies to get the weight of shipment. The shipping cost is often relative to the weight of the package.

The normal floor scales are the ones that have the flat and wide areas. It can handle tons of weights. This is usually made of the strongest stainless steel materials to prevent corrosion and be able to handle even heaviest items.

The manual types require some computation from the user. This means that the operator of the floor scale will have to adjust the indicator of the weight. There are also digital types. This is using dry cells as its power indicator. It is more accurate than the manual.

The floor scales also vary in sizes. The big industries use the large variety, while the while the smaller ones are enough for use at homes. The big industries use floor scales to measure their materials to be used in production. Others use the floor scales for weighing objects before shipping them to the destination. The popular small floor scale is the bathroom weighing scale. This is one portable. This is used at home to monitor the health of the family member. This determines if the family member is already overweight or gaining some pounds.

Floor scales are expensive. The prices depend on the sizes and the different features. Make sure to take care of this item properly because a defective scale will not give you an accurate measurement. A faulty measurement might affect the business or other important personal things one is watching out for.

Most companies offer free calibration. Make sure you calibrate regularly because accuracy is affected with continued use. Learn how to calibrate yourself. It is a fairly simple process.

The floor scale that you are buying should have at least one year warranty. Smaller types are usually free of charge when it comes to delivery. Some agents offer free services in cleaning also. Dirt could affect the accuracy of the scale so that it is important to keep the machine clean. The mechanism may also malfunction if dirt accumulates inside.

The other types of scales are the balance weigh scale, spring scale, Hydraulic or pneumatic scale, and digital weigh scales.

Balance weigh scale is the using of different weights in one end and putting the object to be weighed in the other end. They have sliders that use equilibrium in determining the weight. The spring scale weighs objects by the use of gravitational force. The object is hanged on a hook, and the gauge pulls on the reading.

Hydraulic or pneumatic scale uses hydraulic force in measuring the weight of an object. The digital scale is the most modern so far. This uses electronic circuitry to measure the weight. It is also the most accurate.

Laboratory Experiment Questions Please help!!?

Can you please help me in my EE Theory Laboratory Subject?
These are the questions in our experiment.

1. It depends on what the expected measured voltage is. you would use a suitable voltage range. ie if the expected voltage was 0.3V you would use 3-V range at max and vice versa.

2. Can not answer as you havent stated what your trying to draw or show on the osciloscope.

3. I assume this relates to the scaling on a multimeter? the scaling increases in decades so your answer is likely to be around 5 * scaling range.

4. When measuring voltages across resistors, the voltmeter is placed in parallel to the resistor. Make sure you have the pos/neg around the right way or you get a negative value. cant show u a circuit diagarm

5. When measuring the current flowing through a resistor you need to put the ammeter in series with the resistor. specifically at the negative side of the resistor. again cant show a diagarm.

6. precautions; terminal polarity, voltage is measured in parallel, current is measured in series. multimeter settings, ie circuit wired correctly, and set to measure voltage or current or resistance. also make sure u do not hold the resistor as your body will affect your result.
