A pyrometer is capable of producing a voltage by __________.

Question 1 of 27070

A pyrometer is capable of producing a voltage by __________.

🔍 Key Concepts

• pyrometer as a temperature-measuring device • how temperature can be converted into electrical voltage • basic physical effects used in sensors: chemical, photoelectric, thermoelectric, piezoelectric

💭 Think About

• Ask yourself: which option describes a common way of measuring high temperature on machinery or exhaust systems? • Consider which effect is specifically based on temperature difference between two materials rather than light, chemicals, or pressure. • Think about where you’ve seen pyrometers used on ships (e.g., exhaust gas temperature) and what kind of sensor tip they typically use.

✅ Before You Answer

• Eliminate choices that clearly relate to light or mechanical pressure, because a pyrometer is mainly for heat/temperature. • Identify which choice involves two different metals and a temperature-dependent voltage. • Confirm that the option you choose matches how thermocouples work, since many pyrometers are based on that principle.
