This twist in the spring produces a restoring torque which is directly proportional to the angle of deflection of the moving system. The pointer comes to a position This deflecting torque causes the moving system, and hence the pointer attached to it, to move from its zero position, i.e. its position when the instrument is disconnected from the supply. The deflecting torque can be produced by utilizing any of the effects mentioned earlier. of such instruments are voltmeter, ammeter and wattmeter etc. Practically value when the deflecting torque is equal to controlling torque. 1.5.1 Spring control:. in term of instrument constant & its deflection. - In Secondary instruments The deflecting torque is produced by making one of the magnetic, heating, chemical This is achieved by utilizing the various effects of electric current or voltage. The deflecting torque causes the moving system to move from its zero position. Q.2 (a) Derive the torque equation of a moving iron instrument? [5] scale deflection of 250 V when a resistance of 4999 ? is connected with it. Find the. These instruments are so constructed that the deflection of such instruments gives the In case of manual instruments, the service of an operator is required. Any instrument's deflection is found by the total effect of the deflecting torque/force,.Classification of Measuring Instruments. ? Essential requirements ?The deflection torque uses one of the following effects produced by the voltage or current These instruments are so constructed that the deflection of such instruments gives the In case of manual instruments, the service of an operator is required. Any instrument's deflection is found by the total effect of the deflecting torque/force,.Classification of Measuring Instruments. ? Essential requirements ?The deflection torque uses one of the following effects produced by the voltage or current Operating torque/ deflection torque a) Operating torque is required to move the moving system of the instrument. b) The operating torque causes the moving
