Electronic Weighing scale


A weighing scale is a measuring Instrument used to measure the weight of object/s.

An electronic weighing scale is a measurement device instrument that is used to measure weight. It is equipped with a Transducer which converts one form of energy into another. It works on the concept of a strain gauge load cell [transducer], which senses weight and converts it into an electrical signal which can be measured and recorded by an electronic display on the machine.

Difference between Weighing Scale & Weighing Balance

1] An instrument with readability > 10 mg is classified as Electronic weighing scale and an instrument with readability ≤ 10 mg is classified as Analytical balance.

Weighing scales and balances are accurate, the level of precision they offer differ . Following is a list of scale and balance types based on their level of accuracy/precision to a decimal place.

  • Weighing scale - .1g 
  • Standard precision balance - 0.01g - 0.001g (2-3 decimal places)
  • Analytical balance - 0.0001g (4 decimal places)

An electronic analytical balance, works on different weighing technologies.

One of them use a strain gauge load cell design where you have two metal plates with some form of strain material in between them. The strain material can be made out of nickel alloy or ceramic which are both very sensitive to being stretched or compressed.

Secondly

Electro Magnetic Force Restoration Technology [EMFRT] uses magnetic field and produce an appropriate current to hold the lever balanced in the null position (Equilibrium) for any weight placed on the pan. The amount of current produced is proportional to weight placed on pan.

Thirdly

In tuning fork technology, the frequency increases / decreases according to the loaded weight, which is counted and output digitally generated.

Weighing scales measure weight.

A wide variety of products can be weighed using this type of scale, including small parcels and standard-sized packages like those delivered through the postal service.

Precision balances, compact balances, analytical balances, Semi Micro Balance and Micro balances are some of the types of balances used in laboratories


Digital Weighing scale


Essae weighing scales are based on 100% precision and accuracy, apart from infusing modern digital technology in all its products. Accuracy is a one-time factor, whereas precision is something you should look for, every time you buy a weighing scale. If you measure your weight multiple times and it generates different readings, that means the scale has low precision. On the contrary, if you get the same measurement time after time, it indicates perfect level of precision.

To test if the weighing scale is precise and accurate,

  • Make sure that the scale reads ‘zero’ at the beginning.
  • Place an object of your choice on the scale and observe the weight.
  • Now, take off the weight and observe.
  • The scale should fall back to zero automatically.

You can repeat the same process and make sure that the scale shows the same reading in every round.

This would indicate that the scale is completely accurate.

But, if the scale shows a reading different than the previous one, be it by a 0.5-pound or 5-pound difference, you should recalibrate your device and check again (However, check the internal and external conditions of the scale for in-depth clarity)

Be sure to select a scale with enough capacity to weigh your items plus a little bit of padding for rough treatment. The second part will be to determine how small of a change in weight you want to be able to display, also known as the scale's readability.

A test weight can be used to determine the correctness of a digital weighing scale. The readings of the test weight can be recorded and compared at various times or Place one object on the scale. Note the weight. Weigh again at different times If each time readings match, the scale is accurate.

Digital scales work with the use of a strain gauge load cell. When you place an object on a digital scale, its weight transfers to the load cell, which distorts the pressure of the system and generates electrical power proportional to the deflection of the load cell.

Considering

  • Accuracy – Digital weighing scales are more accurate than Analog weighing machines.
  • Mechanical components are more in Analog scales than Digital scales.
  • Digital scales are more durable than Analog scales considering component ware and tare.
  • Rate of breakdown is more in Analog scales than Digital scales.
  • Functionality of Digital scale is higher than Analog .For example – Weight readings are digitally displayed in Digital machines.
  • Digital weighing scales can be connected to a computer, compatible with smart phones, weight data can be further used to perform various functions whereas Analog machines are very conventional.

GPS Clock


GPS Synchronized Clock working principle:

GPS wireless clock is a very precise clocking system that uses the GPS (global positioning system) satellite technology. These satellites scattered around the earth records time with 100% accuracy until the smallest fractions of a second and then therefore transmit those time data’s into various locations on Earth.

The GPS data receivers which can be positioned anywhere like on rooftops of buildings, windows of different facilities in turn gets these data transmissions and afterwards relay it to the master GPS transmitters installed in various facilities.

A GPS wireless clock is made up of a transmitter, system clock and a GPS receiver. The clock will start functioning after getting powered by a SPECIFIED form of power source. Once it gets started it doesn’t needs any manual adjustments as it will measure precise time automatically. Its functions are to provide accurate time always without having the need for any modifications and adjustments.

The Global Positioning System (GPS) is a network of 24 satellites in circular orbits around the Earth. Each satellite carries a highly accurate atomic clock (along with several backup clocks) and emits timed signals that include a code detailing its location. By analyzing a combination of signals from at least four of these satellites, a GPS receiver on the surface of the Earth with a built-in microprocessor can receive the accurate time information along with location of the receiver (latitude, longitude & altitude).

The GPS satellites transmit UTC (Universal Co-ordinated Time) information to a GPS receiver in the Master installed in the facility. Based on this reference, the RF Transmitter in the Master re-transmits the local time information via a radio frequency signal @866Mhz to wireless digital clock (s) in the facility. Distance coverage from Master to Clock depends on actual site conditions, layout and line of sight .

As a result, all wireless clock(s) in the system are precisely synchronized to Master and therefore to atomic time. Essae’s GPS synchronized clocks systems consist of master (s) and as many clock(s) as may be required.

A Digital clock with GPS Synchronization is made up of a transmitter, system clock and a GPS receiver .Its functions is to provide accurate time always without scope for any modifications and manual adjustments.

It starts functioning when provided with power supply. Once it gets started it doesn’t need any manual adjustments as it will measure precise time automatically. precise time automatically. Its functions are to provide accurate time always without having the need for any modifications and adjustments .
