The calibrated scale of the potentiometer (and of any analog meter) acts only as a simple mechanical analog-to-digital converter and, in the case of a non-linear device (e.g., an ohmmeter), as a functional converter. y̑�;\͖i�����ۧH�j&�B�q,�v����}Y�`{�+њ�\@ӡ��y]�j�̳yE���`~�bE��B�5.��uV����������iZf8��%�q�8F� 2) Bridge circuits: These convert the physical quantity to be measured into the voltage. endobj By using the meters, it can be measured easily. These potentiometers are electro-mechanical transducers that convert the rotary or linear displacement into a change in resistance. IBS Electronics Services. <> Linear potentiometers are, essentially variable resistors whose resistance is varied by the movement of a slider, Figure 1.23 illustrates the basic principle of a linear potentiometer. For example, in a loudspeaker, a potentiometer is used to adjust the volume. This site uses Akismet to reduce spam. C. Passive device and converts mechanical displacement into a change of resistance D. Active device and converts electrical displacement into a change of resistance View Answer / Hide Answer. • This device converts linear/ angular motion into changing resistance that may converted directly to voltage and/or current signals. Additionally, he has interested in Product Design, Animation, and Project design. Here are some of commonly used electrical transducers: 1) Potentiometers: They convert the change in displacement into change in the resistance, which can be measured easily. To measure the displacement, a potentiometer is typically wired as a “voltage divider” so that the output voltage is proportional to the distance traveled by the wiper. <> displacement and pressure. Potentiometers convert rotary motion or linear displacement into a change of resistance, supplying a smooth transition of voltage or current levels. endobj and other characteristics of audio signals. Linear potentiometers are sensors that produce a resistance output proportional to the linear displacement or position. To measure the displacement, a potentiometer is typically wired as a “voltage divider” so that the output voltage is proportional to the distance traveled by the wiper. Precise Position Performance. The resulting voltage output may be used to control position transducers in a wide variety of potential transportation, industrial and medical applications. stream ��S�w��\��H�5\�,��r�zq���4C_��9�%_�Y��%(�c~�Tt��٨V-�D�CPRq��n�Wu�����(���������T��b�i�ڠ�az�l����x��MJ���0��;�Uh� @bY�sZUYU����4l\�����9@������٠)!B�meVK��Qb��J(�2� Tolerance: Like mechanical potentiometers, digital potentiometers don’t have tight resistance tolerance. stream Required fields are marked *. •They are useful for measurement of large amplitudes of displacement. the number of turns per unit distance and it is affected by the loading effects of the voltage divider circuit. Read more about this portal or Sachin Thorat click on below button! The following Factors are to be considered while selecting the potentiometers. Introduction to Slotting Machine : d. Active device and converts electrical displacement into a change of resistance. • Potentiometers: consist of a resistance element provided with a sliding contact called wiper. <> The sensor itself may be made from a coil of wire over which a moving contact or wiper causes a change in resistance between the terminals of the device. The potentiometer can be used for the measurement of translational as well as well rotational displacement. Potentiometers values are often marked with a readable string indicating the total resistance, such as "100k" for a 100 kOhm potentiometer. They are one of the common types of Pots. Figure 1.23 illustrates the basic principle of a linear potentiometer. It is a type of resistive displacement sensor. <> Its function is to convert the mechanical displacement into an electrical signal.
