In the ancient period itself, the concept of well pump has discovered and moving on from that period, there were many progressions and changes that happened in the development of the pump’s design, construction, functioning, and others. The one kind of pump which we are going to discuss today is “Submersible Pump”. In the year 1916, Armais Sergeevich Arutunoff initially coined this pump, and the first usage was after the 1950’s only. Initially, these … [Read more...]
What is an Ohmmeter : Working Principle & Its Types
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 a Capacitor Bank : Working and Its Calculation
When a number of capacitors are connected together it forms a capacitor bank. They can be connected in series or parallel. A capacitor bank has numerous advantages and applications. Most of the time, these are used for reactive power compensation and power factor improvement. The arrangement of these can be done at substation or power plants. The unit for capacitance in Farads. A capacitor bank of lower scale is frequently used in industrial buildings, … [Read more...]
What is a Stepper Motor – Construction, Operating Principle & Uses
It is a type of motor used for precise movements and positioning of objects mainly in milling machines. It is a brushless type synchronous motor and it is operated stepwise. This step-wise rotation is considered as the step angle. One step angle is the rotation of the shaft per one step. The step angle can be of different degrees depending upon the construction of the rotor and stator teeth. The brushless motor rotates the shaft 360 degrees per one … [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 Resistivity and Its Variation with Temperature
Resistivity implies the measure of the resistance offered by an element for a given dimension at a particular temperature. Based on the resistivity, properties and characteristics of the element can be found out which are very important while designing a particular circuit, or applications. Even, based on its values, the element is categorized as conductor, insulator, or semiconductor. It need not be confined to only electrical property like the flow of … [Read more...]
What is an Inverter : Working Principle, Classification & Applications
An inverter is one of the most frequently used electronic circuits in most of the applications. It’s a circuit that converts fixed DC supply to alternating AC supply to feed AC loads. Widely used in commercial, aviation, residential and industrial applications. It could be regarded as the backbone for most of the applications. It is frequently used as an interfacing unit between DC supply and load. In many cases, it acts as an interfacing unit between AC … [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...]
