Electrical Measuring Instruments And Their Uses

Electrical insulation mercury barometer.

Electrical measuring instruments and their uses. Before this article i have shared an electrical measuring instrument covering all different instruments and their uses. 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. A direct measuring instrument measures the electrical unit by reading and deflection. This is the second article based on the electrical instruments classification of electrical measuring instruments.

2 measuring instruments used as the controllers. 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 measuring instrument which is used to measure the electric current in a circuit is known as an ammeter. Basically there are three types of measuring instruments and they are.

Find the current range of the instrument when used as an ammeter with the coil connected across a. Masses of ions used to identify chemical substances through their mass spectra measuring cup. Name purpose ammeter ampermeter measures current capacitance meter. The instruments duty is to measure the given specimen according to the given dimensions.

Below is the list of measuring instruments used in electrical and electronic work. What is an electrical measuring instrument. A spoon used to measure an amount of an ingredient either liquid or dry megger. The main functions of the measuring instrument are indicating recording detecting controlling and testing the electrical units.

Measures current without physical connection curve tracer. For instance when a certain value of the pressure is reached the measuring instrument breaks the electrical circuit which stops the running of compressor. The classification of an electrical measuring instrument is based on the nature of the operation function purpose uses and many other terms. So in today s class we will be discussing on types of measuring instruments and their uses in engineering workshop.

Measures the capacitance of a component current clamp. 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. Liquid and dry goods measuring cylinder. Measuring instruments plays a vital role in the engineering workshop.
