INSTRUMENTATION FINAL NRCC | 121 QUESTIONS AND
ANSWERS | LATEST UPDATE WITH COMPLETE
SOLUTION
What does an O2 sensor in a boiler stack do? Answer - To make sure the boiler
is running efficiently and make sure there is a good fuel to oxygen ratio.
Intrinsically Safe Answer - A protection feature for the safe operation of
electronic equipment in explosive atmospheres and/or under irregular
operating conditions.
What are three temperature scales? Answer - Fahrenheit, Celsius, Kelvin
Manometer Answer - A device for measuring pressure with a liquid filled tube.
Thermowell Answer - A closed tube used to protect a temperature instrument
from process conditions and allow instrument maintenance to be performed
w/o draining the process fluid.
What is OSHA? Answer - Occupational Safety and Health Administration is a
federal agency that develops and enforces workplace safety guidelines.
ControlNet Answer - A Real-time device network providing for high-speed
transport of time-critical I/O data, messaging, peer to peer communications,
and the uploading and downloading of programs.
, DeviceNet Answer - Byte-wide network that can support 64 nodes and a
maximum of 2048 field I/O devices.
DIN rail Answer - A narrow channel of metal - made of bent sheet steel or
extruded aluminum - with edges designed for plastic components to "clip" on.
Endothermic reaction Answer - A reaction that ABSORBS energy in the form of
heat. Therefore more heat and energy needs to be added to sustain the
reaction.
2 Ways heat is transferred Answer - convection and conduction
Viscosity Answer - A liquid's resistance to flowing
hygrometer Answer - A humidity analyzer that measures the physical and
electrical changes that occur in various materials as they absorb or release
moisture.
triple point of water Answer - temperature and pressure at which water will
coexist as a solid, liquid, gas.
Static Head Answer - Pressure of a fluid due to the head of fluid above some
reference point.
Material Mass Flow Meter Answer - Is used to measure the actual quantity of
mass of a flowing liquid.
