Initially, ohmmeters were evolved based on the design construction of a meter known as “Ratiometer”. Ohmmeters under this classification only calculate the value of resistance because they are not simply integrated into the multimeter construction. Insulation testers which depended on a hand moved generator also works on a similar operation. This makes sure that indication was completely autonomous of the developed voltage. Following this, various designs … [Read more...]
What are Digital Sensors : Types and Their Uses
Electrochemical and electrical sensors are usually one part of the measuring sequence. And this sequence generally comprises of a sensor, transmitter, and a cable. And the foremost classification of sensors is analog and digital. The digital sensor technology is more substantial in regard to its extensive reliability and exactness. Digital sensors are the contemporary replacements of analog sensors because of few drawbacks in the analog type of sensors. … [Read more...]
What are Analog Sensors : Types and Their Characteristics
As we all are living in digital technology, the one device that became an integral part of our daily activity is Sensor. Every device which we come across in our home from mobile phone to security systems at home, all are embedded with various kind of sensors. So, a sensor is a device that observes changes occurring in the parameters such as humidity, pressure, temperature, and others and sends the output to either microcontroller or microprocessor. And … [Read more...]
What is Peristaltic Pump : Working Principle & Its Applications
A peristaltic pump is one of the most frequently used pumps for transferring liquids from one point to another. Mostly it is used in medical applications and laboratory applications. In medical applications like dialysis, it proves very useful to transfer blood from one part to another part. The best thing in this pump is the liquid to be transferred does not comes in contact with the pump. It remains in the pipe which is used to carry or transfer the … [Read more...]
What is a Variable Resistor : Working Principle & Its Applications
The variable resistor is an element that offers variable resistance to the circuit. By adjusting its internal configuration, we can obtain variable resistance at the load side. This element is frequently used in electrical and electronic circuits to vary the current flowing in the circuit. Apart from varying current, this element is also used to control some basic parameters like speed, temperature for commonly used electrical loads. A simple example would … [Read more...]
What is a Steam Turbine : Working, Types & Its Applications
Steam turbines are available from the past 100 years and these are manufactured and used in different plants like the combined cycle, fossil power, nuclear plants. The first steam turbine was designed in the year 1884 by Sir Charles A. Parsons. This turbine was simply generated 7.5 KW of energy and used in Newcastle, England for lighting an exhibition. At present, steam turbines can generate above 1,000 MW of energy which is used in major power plants. The … [Read more...]
What are Welding Types : Working and Their Applications
Well, we are no more in the bewilderment of how metals or thermoplastics are joined or attached, because we live in the era of extensively implementing various welding types. So, welding is one of the most prominent employment that was born several millions of years back. The only welding process that was in evolution until the 19th century was forge welding. The advancements in technology have shown multiple progressions in this welding and allowed us to … [Read more...]
What is Cascode Amplifier : Circuit, Working & Its Benefits
Well, We all know that the prominent usage of an amplifier is to amplify the signal strength whether the signal may be amplitude, frequency or other. So, the initial device which came into evolution to amplify the signal was the triode vacuum tube in the year 1906. The enhancements in digital electronics from the 20th century onwards offered modern approaches that are being added to the conventional amplifiers through digital switching so that … [Read more...]
What is a Surge Protector : Types & Applications
We might often come across situations of facing damage to electronic devices. This happens because of multiple scenarios like atmospheric changes (lightning and thunders), voltage breakdowns, and utilization of heavy devices such as compressors. These all interruptions might enforce destruction to the electric equipment. And the one device which comes into a scenario to protect from this condition is Surge Protector which is also termed as a surge … [Read more...]
