And static characteristics are the characteristics that changes very slowly or remains constant. b) False Curve ‘b’ shows the output characteristic of a transducer with a marked non-linear behaviour throughout the measurand range. The linearity error is expressed as a percentage of the maximum electrical output value. View Answer, 14. Precision is normally expressed as a percentage of FSO and is sometimes referred to as repeatability. b) 13:603 c) 2.125 d) 13:619 c) 6% To practice all areas of Mechatronics, here is complete set of 1000+ Multiple Choice Questions and Answers. d) 13:619 b) 7.09% The use of these elements and devices is not limited to measuring systems. The choice of this straight line depends on the device output curve and its applications; as shown in Figures 1.2-1.5 there are four main types of curve used for linearity calculations: The straight line between the theoretical end points. Static Sensitivity 2. View Answer, 9. Static characteristics: The set of criteria defined for the instruments, which are used to measure the quantities which are slowly varying with time or mostly constant, i.e., do not vary with time, is called ‘static characteristics’. Analytic expressions are presented for the fluxes in the parallel rods of the magnetic circuit, the field strength between them, and the static characteristics of a magnetic transducer with plane windings. a) 13:719  Transducer is a converter of any one type of energy into another. 2.4: The Common Characteristics of Transducers 2.4 The Common Characteristics of Transducers All transducers, irrespective of their measurement requirements, exhibit the same characteristics such as range, span, etc. See Figure 1.6. c) 6% View Answer, 12. Static Characteristic; Dynamic Characteristic; So let me give you an overview of each one of these characteristics. Related posts: Static Sensitivity of an instrument or an instrumentation system is defined as the ratio of the magnitude of the output signal or response to the magnitude of an input signal or the quantity being measured. View Answer, 3. View Answer, 11. What is the mean value of a distance observation set taken by a distance measurement sensor? 4. View Answer, 13. Static Characteristic: So let's start with static characteristics, this type of characteristic generally not change so much with the time, you can say this static characteristic most probably constant with the time. Linearity 3. If we assume that the true output has a linear relationship with the input. But if the physical force is converted into an electrical signal, then their value is easily measured with the help of the meter. View Answer, 8. View Answer, 10. a) True Precision–can be defined as the tolerance within which a measurement can be repeated (e.g. The number and variety of sensors is very large indeed. Static & Dynamic Characteristics of Instruments P M V Subbarao Professor Mechanical Engineering Department A Step Towards Design of Instruments…. Mention the purposes of the measurement. Precision–can be defined as the tolerance within which a measurement can be repeated (e.g. a) 12% d) 5.07325 from zero to 100%) and then in the decreasing direction (i.e. Usually 0-100% for both FSO and range-in which case it is called the ‘terminal line’ (see dotted line in Figure 1.2)-or it can purposely be offset to suit certain applications (see broken line). Drift Dead Zone ... TRANSDUCER Thetransducerisdefinedas the formofenergyintoanother form Example: Temperature transducers Thermocouples Resistance-Temperature Detectors (RTD) What is the relative accuracy ratio of an observation taken by a IR(Infrared) sensor which predicts the distance of an object to be 1.26 cm but the actual distance is 1cm? c) Null and deflection methods d) Input – Output configuration a) 12% STATIC CHARACTERISTICS Application involved measurement of quantity that are either constant or varies slowly with time is known as static. b) 2.2 A line midway between the two parallel straight lines which are closest together and envelop all the output values obtained during calibration  (see broken line in Figure 1.4). 13.
