It can also tell about the angle between the voltage and the current measure if needed. 4. It is easy to calibrate and quick to use, the user just needs to connect the two probes of the meter to the DUT as shown below: Transducer This article is about an engineering device. For the similarly named concept in computer science, see Finite state transducer. A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.). The process of converting one form of energy to another is known as transduction. various types of transducer measurement of strain gauge A strain gauge is a device used to measure strain on an object.

  • Chapter 5 : Power Meters
    EE 101 MEASUREMENT Power Meters / 1 CHAPTER 5 : POWER METERS 5.1 Power Meter Power meter is electric meter : and define as a meter for measuring the amount of electric power used in watt of any given circuit. Figure 5.1 : Power Meter 5.2 Principles of Analogue Wattmeter W P Figure 5.2 : Symbol of Power Meter The traditional analog wattmeter is an electrodynamics instrument. The device consists of a pair of fixed coils , known as current coils , and a movable coil known as the potential coil . The current coils connected in series with the circuit, while the potential coil is connected in parallel . Also, on analog wattmeters, the potential coil carries a needle that moves over a scale to indicate the measurement. A current flowing through the current coil generates an electromagnetic field around the coil. The strength of this field is proportional to the line current and in phase with it. The potential coil has, as a general rule, a high-value resistor connected in series with it to reduce the current that flows through it. The result of this arrangement is that on a dc circuit, the deflection of the needle is proportional to both the current and the voltage , thus conforming to the equation W=VA or P=VI . On an ac circuit the deflection is proportional to the average instantaneous product of voltage and current, thus measuring true power, and possibly (depending on load characteristics) showing a different reading to that obtained by simply multiplying the readings showing on a stand-alone voltmeter and a stand-alone ammeter in the same circuit.
