Measurement system in engineering - Essay ExampleThese were, at best, crude dodges which gives a feel of the order of the physical quantity. They do not provide accurate measurements and therefore cannot be recorded and kept for future reference.To overcome this, a new type of device was created. This is called transducer. These transducers are use to convert mechanical quantities into electrical signals which can be recorded. Measurement systems started gaining prominence in engineering and a new genre called orchestration engineering was born.This is done using Strain gauges. Strain gauges are constructed with materials whose electrical unsusceptibility value changes when force is applied on them. The variation in resistance is directly proportional to the force applied. The variation in resistance can be measured using a wheatstone bridge or a fair voltmeter-ammeter method.The basic strain gauge is used in the industry in weighing scales, weighing systems etc. Different varia tions of the corresponding are also used in metre tension in a material (like paper, steel strip etc) as tension is also essentially force. A variation of the same can also be used to measure torque - which is the angular force i.e force x distance.There are several styles of measuring pressure level. The cruder ways of measuring pressure using manometers or bourdon tubes have now been replaced by more sophisticated measurement techniques. The most common way to measure pressure of a hunt downing liquid is to use a venturi. As the liquid passes through a venturi, the velocity of the liquid increases and the corresponding pressure decreases known as Bernoullis Equation (FlowMax engineering,n.d.) This principle is used to measure the pressure.As a derivative of the same, the venturi meter can be used to measure flow of the liquid as well since flow is proportional to square root of the pressure drop. An electronic circuit to generate the
