A capacitive pressure sensor has a typical measurement uncertainty of A. Direct radiation only B. Diffuse radiation only C. … Pyranometer is used to measure total hemispherical radiation - beam plus diffuse - on a horizontal surface. 1. A typical, laboratory-grade pyranometer is essentially just a thermopile (a collection of thermocouples, perhaps 50–100 in the best instruments) mounted on a black carbon disc, which generates electricity according to how hot it gets (how much solar radiation falls on it). Potentiometer transducers are used for the measurement of A. One B. A Pyranometer is a device use to measure the “total hemispherical solar radiation”. The total irradiance (W/m 2) measured on a horizontal surface by a pyranometer is expressed as follows: Most of solar resource data come from pyranometers. Following is the list of multiple choice questions in this brand new series: MCQ in Tests and Measurements . For example, amplification is needed for thermocouples, which have a typical output of only a few millivolts. If the displacement is measured with strain gauge then the number of strain gauge normally required are A. According to application, instruments are classified as (a) switch board (b) portable (c) both (a) and (b) (d) moving coil (e) moving iron ± 0.2% Pressure B. Displacement C. Humidity D. Both (a) and (b) View Answer / Hide Answer MCQ in Tests and Measurements part 3. The total solar radiation arriving at the outer edge of the atmosphere is called the “|Solar constant”. You can send your comments directly at info@mechanicaltutorial.com. A pyranometer is used for mesurement of..... A. This is used to amplify low-amplitude outputs from the primary transducer or variable conversion element, thus improving the sensitivity and resolution of the measurement. ANSWER: D. Four . If the same ammeter is used to measure a full-scale current of 1.0 ampere, what is the value of the shunt resistor in ohms if the voltage across the meter is 9.0 volts? Topic includes Analog and Digital meter, Oscilloscope, RF meters, Signal and Noise Generators, Reflectometer, Instrumentation. These short objective type questions with answers are very important for Board exams as well as competitive exams. These short solved questions or quizzes are provided by Gkseries. If shaded, a pyranometer measures diffuse radiation. Multiple Choice Questions (MCQ) on Measurement and Instrumentation for Electrical Engineering. Pressure Measurement - MCQs with answers Q1. An ammeter has a full-scale deflection current of 100 mA. Pressure Measurement Multiple Choice Questions and Answers for competitive exams. Q2. Explanation: A Pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface and it is designed to measure the solar radiation flux density from the hemisphere above within a wavelength range 0.3μm to 3μm. 7.
