Pyrometers commonly found on diesel engine exhaust systems consist of __________.

Question 1 of 27070

Pyrometers commonly found on diesel engine exhaust systems consist of __________.

🔍 Key Concepts

• Pyrometer function in diesel engine exhaust systems • How thermocouples measure temperature and what kind of meter they need • Difference between voltmeter and ammeter in temperature-measuring circuits

💭 Think About

• Which device in the choices is normally used to sense high exhaust temperatures without direct electrical power? • When a thermocouple senses temperature, what type of electrical signal does it produce—voltage or current? • Looking at the options, which combination matches how a simple exhaust temperature gauge on an engine panel is usually wired?

✅ Before You Answer

• Identify which option includes thermocouples, since these are standard for exhaust pyrometers • Decide whether a thermocouple output is read as voltage or current on the panel instrument • Eliminate any choice that uses a sensing method more suited to pressure than temperature
