This is parallax error. due to wear or drift behaviour. It was interesting that you said calibration should be done before and after every important measurement. These range from greater overloads, falling down and extreme temperature conditions to interventions in the equipment for repair purposes. In other words, if a measuring amplifier is used in a test bench where the operating conditions are hard and the costs high, and measurement results are shown at a later stage to be untrustworthy, it may be sensible to implement a recalibration after six or even three months. This is because the opposing effect is measured with the help of the standards which have a high degree of accuracy. Your email address will not be published. Share.

Sure Controls – Responsive to Our Community. If the deviations measured during a calibration compared to the previous calibration lie within the metrological requirements, then the measurement results obtained with the measuring equipment are justifiable. Most of the quantities can be converted by transducers into the electrical or electronic signals. Here we are interested in electrical measuring instruments so we will discuss about them in detail.Electrical instruments measure the various electrical quantities like electrical power factor, power, voltage and current etc. There are four types of validity; face validity, criterion validity, content validity or construct validity [20],[21].

It's easy to be used, must not to be calibrated, costs less than a scale. No advantage, they are different devices. Disadvantages Due to addition Of Different weights involved this method become little difficult. However, in practice, the question more frequently posed is how often should a recalibration actually be carried out and who is responsible? Advantages Of Using Certain Measuring Instruments? The decision on how long a measurement instrumentation calibration interval should be must therefore take into consideration, how high the costs are, on the one hand, for more frequent calibration (including time lost) and, on the other hand, for possibly worthless measurement results, re-measurements, recall actions, etc. Your email address will not be published. In this case, the AC meter has a resolution of 1 mV … Advantages And Disadvantages Of Null-Type Method Advantages  They are Very much Accurate. It is especially appropriate for testing wires, structural steel, heavy plates, and a number of plastics. With regards to intervals, if internal specifications for recalibrations are available, e.g. The laser tape measure is one of the newest types, offering many advantages compared with older, more traditional models. (c) Electronic measuring instruments. As a process, validation involves collecting and analyzing data to assess the accuracy of an instrument. The operator can instead obtain a very good idea, by continuously tracking the calibration results, of the long-term behaviour of the equipment that he uses under the operating conditions valid for the application. Over time, there is a tendency for results and accuracy to ‘drift’ particularly when using certain technologies or measuring specific parameters, such as temperature and humidity. This way he can save time and have peace of mind that all of his measurements are done correctly. Advantages and Disadvantages of Pneumatic Instruments The disadvantages of pneumatic instruments are painfully evident to anyone familiar with both pneumatic and electronic instruments. They need only to be placed in one area and faced toward a hard surface of another area to correctly gauge a distance.

I'm the Editor here at Process Industry Informer, where I have worked for the past 17 years. 3. Advantages of Electronic Measurement The advantages of an electronic measurement are 1. Modern thermometers measure air temperature without the use of mercury; the electronic reading is an exact one. First, we will discuss the pros or advantages of digital multimeters. Barrie A. Gregory, Retired, in Encyclopedia of Physical Science and Technology (Third Edition), 2003. 1 decade ago. Moving Iron or MI Instrument Definition: The instrument in which the moving iron is used for measuring the flow of current or voltage is known as the moving iron instrument. For those measurements where the highest demands are placed on precisely known measuring properties, it must be noted that the calibration can only make valid statements at the time of implementation. If the pointer of an analog multimeter is viewed from a different angle, you will see a different value. The height gauge is a type of testing and measuring instruments majorly into layout tools measurement. Advantages & Disadvantages of Level Measurement Systems like ultrasonic level transmitters, float level measurement, Displacer level instruments, Pressure based level measurement.
