Question 65Motor Plants - 1st Asst/Chief

The correct answer is C) comparator type mist detector for large low-speed, crosshead type engines. This is the correct answer because the illustration MO-0008 depicts a comparator type mist detector, which is a device designed for use in large, low-speed, crosshead type diesel engines. Comparator type mist detectors are specifically used to monitor the oil mist in the crankcase of these types of engines, which are commonly found in large ships and vessels. The other answer choices are incorrect because they describe different types of devices (level type explosimeter, rotary type mist detector, and photoelectric explosive gas indicator) that are not depicted in the illustration and are not typically used in the same applications as a comparator type mist detector.
