Join our social networks below and stay updated with latest contests, videos, internships and jobs! The transduction mechanisms are based on the change in resistance brought about by the measured. a) True b) False. Maxwell bridge configuration for measurement of inductance and De Santy’s bridge for measurement of capacitance Maxwell Wein bridge configuration for measurement of inductance and De Santy’s bridge for measurement of capacitance a) electrical signal 10 0 obj (2 Points) Frequency Signal conditioning Transformers Transducer 18 Potentiometric resistance transducer measures (2 Points) triangular displacement rectangular displacement square displacement linear displacement 14 Piezoelectric transducer is used for measuring (2 Points) any quantity chemical quantities electrical quantities non-electrical quantities 11 Sensors produce frequency which is … The potentiometer is the electrical type of transducer or sensor and it is of resistive type because it works on the principle of change of resistance of the wire with its length. Sensitivity is the smallest value of measurable strain. 5 0 obj A strain gauge measures … An AC generator runs a higher frequency current through the measuring … endobj In a potentiometer, the entire input voltage is applied across the whole length of the resistor, and the output voltage is the voltage drop between the fixed and sliding contact as shown below.A potentiometer has the two terminals of the input source fixed to the end of the resistor. It is a passive transducer. Strain gauges – The resistance of their semiconductor material changes when the strain occurs on it. b) rectangular displacement. d) no elements Simple and inexpensive, have a wide range of applications in measurement systems. b) resistive transducer ... potentiometric transducer : Option-2 : LVDT: Option-3 : capacitive Transducer: 2 0 obj A potentiometric transducer is an electromechanical device. x��Vێ�H}i������+ E��f�F��6/�>4� ����B�~��m0LVHƗ:u���޽�~�>���{��� �7�O.x��`��޸0��n��A�8����� Vt����3��N{w��:�~�� �g>����?��A�_��}{3A䧱D��#W��|w^��'��o��y�7���]�����a;�"�΍����@�\�-C4獄��YV��H��י�N��ޝ���?=���N)s�o麤�e�ɮ�NA&��]�@�1���R��fC��^JC7���5:�f7��c]x���G���"��D�xu��ն��1��.� +��"GW��ʥ�TnhAՇL-ג#�t]Jt�BeJ�.uއM�*6��w���@R�'Fh#����Mq�ZȾ+�u�F�ά:UJ������>� ��_5��aG�*-��r�3��T-1"Sj�&S0��˱兕�/�#�Gg��� To practice all areas of Electrical Measurements, here is complete set of 1000+ Multiple Choice Questions and Answers. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 12 0 R] /MediaBox[ 0 0 612 792] /Contents 10 0 R/Group<>/Tabs/S/StructParents 2>> b) change in weight per unit weight Transducers are used for this purpose. a) linear displacement 3. endstream x��W�n�F��;̑*��%A�� ����(jE-J���Ҏ�oؙYJ��)� ���fg���0� ϟ��_����xy}/o�����HdK��L'��/�E!�١țOA ��N|(�ϛ���{��]Fح-�2���u!g���лWZ�A�o�ٟp��t� a) diameter per unit area a) change in height per unit height Sensors MCQ – Top 10 Multiple Choice Questions on Sensors Electric.

It requires external power source for its functioning. This transducer acts as both primary and secondary transducer. This voltageis … a) linear displacement. it uses the electrical resistance of the conductor to determine the temperature. It is then processed and displayed. c) capacitive transducer c) high efficiency This activity contains 10 questions. Biosensors detects and measures the ions or electrons generated in many reactions, very weak buffer solutions are used in this case. A transducer can be anything that converts one form of energy to another.
