a) analog signal
b) instability
c) ambient condition
d) none of the mentioned
View Answer
Explanation: The conditions of the medium surrounding the measuring device is called ambient condition while a tendency of a system to break into unwanted oscillation is instability.
2. A line midway between two parallel straight lines close together and enclosing all output versus measurand values, on a calibration curve is termed as ______________
a) analog signal
b) best fit straight line
c) ambient condition
d) none of the mentioned
View Answer
Explanation: A line midway between two parallel straight lines close together and enclosing all output versus measurand values, on a calibration curve is termed as best fit straight line while the conditions of the medium surrounding the measuring device is called ambient condition.
3. A mechanical element generally cylindrical shape with cylindrical walls having deep convolutions are the ____________
a) bellows
b) best fit straight line
c) ambient condition
d) none of the mentioned
View Answer
Explanation: A mechanical element generally cylindrical shape with cylindrical walls having deep convolutions are the bellows and a line midway between two parallel straight lines close together and enclosing all output versus measurand values, on a calibration curve is termed as best fit straight line while the conditions of the medium surrounding the measuring device is called ambient condition.
4. A pressure sensing element consisting of a twisted or curved tube of non-circular cross-section which tends to get straightened on the application of internal pressure is the ____________
a) bellows
b) best fit straight line
c) bourdon tube
d) none of the mentioned
View Answer
Explanation: A pressure sensing element consisting of a twisted or curved tube of non-circular cross-section which tends to get straightened on the application of internal pressure is the bourdon tube while a mechanical element generally cylindrical shape with cylindrical walls having deep convolutions are the bellows and a line midway between two parallel straight lines close together and enclosing all output versus measurand values, on a calibration curve is termed as best fit straight line while the conditions of the medium surrounding the measuring device is called ambient condition.
5. _____________ is the range of values over which a measured variable can change without affecting the output.
a) Dead band
b) Capsule
c) Diaphragm
d) None of the mentioned
View Answer
Explanation: Dead band is the range of values over which a measured variable can change without affecting the output while the diaphragm is the range of values over which a measured variable cannot change without affecting the output.
6. _____________ is a sensing element consisting of a thin flexible circular plate which can be actuated by a pressure differential applied across the plate.
a) Dead band
b) Capsule
c) Diaphragm
d) None of the mentioned
View Answer
Explanation: Diaphragm is a sensing element consisting of a thin flexible circular plate which can be actuated by a pressure differential applied across the plate and capsule is a pressure sensing element consisting of two corrugated metallic diaphragms joined along their circumference.
7. _____________ is the rating applicable to a specified operation for a specified uninterrupted length of time.
a) Dead band
b) Continuous rating
c) Diaphragm
d) None of the mentioned
View Answer
Explanation: Continuous rating is the rating applicable to a specified operation for a specified uninterrupted length of time diaphragm is a sensing element consisting of a thin flexible circular plate which can be actuated by a pressure differential applied across the plate.
8. _____________ is a pressure sensing element consisting of two corrugated metallic diaphragms joined along their circumference.
a) Dead band
b) Capsule
c) Diaphragm
d) None of the mentioned
View Answer
Explanation: Capsule is a pressure sensing element consisting of two corrugated metallic diaphragms joined along their circumference and dead band is the range of values over which a measured variable can change without affecting the output.
9. _____________ is the rating applicable to a specified operation over a stated number of time intervals of a specified duration.
a) Dead band
b) Capsule
c) Intermittent rating
d) None of the mentioned
View Answer
Explanation: Intermittent rating is the rating applicable to a specified operation over a stated number of time intervals of specified duration while capsule is a pressure sensing element consisting of two corrugated metallic diaphragms joined along their circumference and dead band is the range of values over which a measured variable can change without affecting the output.
10. _____________ is the complex impedance presented to the output terminals of a transducer by the associated circuitry or load.
a) Lead impedance
b) Capsule
c) Intermittent rating
d) None of the mentioned
View Answer
Explanation: Lead impedance is the complex impedance presented to the output terminals of a transducer by the associated circuitry or load while intermittent rating is the rating applicable to a specified operation over a stated number of time intervals of the specified duration.
