Electrical Measuring Instruments And Their Uses
Liquid and dry goods measuring cylinder.
Electrical measuring instruments and their uses. A spoon used to measure an amount of an ingredient either liquid or dry megger. Generally it is classified into two categories. Electrical insulation mercury barometer. 2 measuring instruments used as the controllers.
Find the current range of the instrument when used as an ammeter with the coil connected across a. 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. A the coil of a measuring instrument has a resistance of 1 ω and the instrument has a full scale deflection of 250 v when a resistance of 4999 ω is connected with it. The instruments duty is to measure the given specimen according to the given dimensions.
So in today s class we will be discussing on types of measuring instruments and their uses in engineering workshop. Basically there are three types of measuring instruments and they are. Measures the capacitance of a component current clamp. Electrical instruments are instruments that use the mechanical movement of electromagnetic meter to measure voltage power current electrical technicians require electrical measurement equipment to check the electrical activity and to detect the presence of voltage or current by using this instrument we can measure electrical parameters such as.
The main functions of the measuring instrument are indicating recording detecting controlling and testing the electrical units. Masses of ions used to identify chemical substances through their mass spectra measuring cup. A direct measuring instrument measures the electrical unit by reading and deflection. Before this article i have shared an electrical measuring instrument covering all different instruments and their uses.
This is the second article based on the electrical instruments classification of electrical measuring instruments. There are number of instruments that can be used as the controllers. The classification of an electrical measuring instrument is based on the nature of the operation function purpose uses and many other terms. Measures current without physical connection curve tracer.
Name purpose ammeter ampermeter measures current capacitance meter. A measuring instrument which is used to measure the electric current in a circuit is known as an ammeter. Measuring instruments plays a vital role in the engineering workshop. The units of measurement for electric current is amperes a earlier ammeters were laboratory instruments which depend on the earth s magnetic field for operation.
