- A.
Mjerni pretvornik
- B.
Mjerno osjetilo
- C.
Regulator
- D.
Izvršni član
Correct Answer
B. Mjerno osjetiloExplanation
The correct answer is "mjerno osjetilo". In a control loop, the elements that react to a physical quantity and measure it are called "mjerno osjetilo" or "sensors". These sensors are responsible for converting the physical quantity into an electrical signal that can be used by the rest of the control system.Rate this question:

Correct Answer(s)
A. Posredno ili neposredno u dodiru s materijom
B. Troši energiju mjerene veličine
C. Prima osnovni signal mjerene veličine i isti daje na izlazuExplanation
The answer correctly states the characteristics of measuring sensors. Measuring sensors are either indirectly or directly in contact with the material being measured. They consume energy from the measured quantity, receive the basic signal of the measured quantity, and provide the same signal at the output. Additionally, measuring sensors also perform energy conversion.Rate this question:

___________________ je razlika vrijednosti veličina na gornjoj i donjoj granici mjernog područja
Correct Answer
Mjerni opsegExplanation
The given statement defines the term "mjerni opseg" in Croatian, which translates to "measurement range" in English. It refers to the difference in values between the upper and lower limits of a measurement scale. The measurement range helps determine the span or extent of values that can be measured accurately using a particular instrument or system.Rate this question:

Correct Answer
B. NetočnoExplanation
The correct answer is "Netočno" which means "False" in English. The statement in the question states that the given conditions (20±5°C; 60±20%; 101,325±2,66 kPa) are the only conditions under which measuring devices can work. However, this statement is not true. Measuring devices can work under various conditions, not just the ones mentioned.Rate this question:

- A.
Dinamička karakteristika
- B.
Prijenosna karakteristika
- C.
Frekvencijska karakteristika
- D.
Statička karakteristika
Correct Answer
D. Statička karakteristikaExplanation
The correct answer is "statička karakteristika". This is because the question is asking about the dependence of the output variable on the input variable without any time dependence. In other words, it is referring to a situation where the output variable is solely determined by the input variable at a specific point in time, without any consideration of changes over time. This is characteristic of a static system or static relationship between the input and output variables.Rate this question:

Graf idealne statičke karakteristike je ___________
Correct Answer
pravacExplanation
The correct answer is "pravac." This is because the term "graf idealne statičke karakteristike" translates to "graph of the ideal static characteristic." In this context, a "pravac" refers to a straight line or a direction. Therefore, the graph of the ideal static characteristic is a straight line.Rate this question:

Eksperimentom u radnim uvjetima tijekom kalibriranja
- D.
To nam zapravo uopće ne treba
Correct Answer
C. Eksperimentom u radnim uvjetima tijekom kalibriranjaExplanation
The correct answer is "eksperimentom u radnim uvjetima tijekom kalibriranja" because the actual static characteristic of a device is determined by conducting experiments in real operating conditions during the calibration process. This involves testing the device under various conditions and measuring its response to accurately determine its static characteristic. This information is crucial for proper functioning and accurate regulation of the device in a control system.Rate this question:

Blizinu stvarne karatkteristike idealnoj linearnoj karakteristici (pravcu) pokazuje _____________
Correct Answer
linearnostExplanation
The correct answer is "linearnost." This is because the question is asking for the term that best represents the close resemblance of the actual characteristics to the ideal linear characteristics (straight line). "Linearnost" is the Croatian word for "linearity," which describes the property of a system or characteristic that follows a straight line relationship.Rate this question:
