Answers | Latest Update
What does an O2 sensor in a boiler stack do? Ans: To make sure the
boiler is running efficiently and make sure there is a good fuel to oxygen
ratio.
Intrinsically Safe Ans: A protection feature for the safe operation of
electronic equipment in explosive atmospheres and/or under irregular
operating conditions.

What are three temperature scales? Ans: Fahrenheit, Celsius, Kelvin
Manometer Ans: A device for measuring pressure with a liquid filled
Guru01 - Stuvia
Expert
tube.
Thermowell Ans: 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? Ans: Occupational Safety and Health Administration is a
federal agency that develops and enforces workplace safety guidelines.
ControlNet Ans: 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 Ans: Byte-wide network that can support 64 nodes and a
maximum of 2048 field I/O devices.
DIN rail Ans: A narrow channel of metal - made of bent sheet steel or
extruded aluminum - with edges designed for plastic components to
"clip" on.
Endothermic reaction Ans: 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 Ans: convection and conduction
Viscosity Ans: A liquid's resistance to flowing
hygrometer Ans: 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 Ans: temperature and pressure at which water will
coexist as a solid, liquid, gas.

Static Head Ans: Pressure of a fluid due to the head of fluid above some
reference point.
Guru01 - Stuvia
Material Mass Flow Meter Ans: Is used to measure the actual quantity of
Expert
mass of a flowing liquid.
Dry leg Ans: Impulse line that is filled with a noncondensing gas used
to protect an instrument.
specific gravity Ans: The ratio of a density of fluid to the density of
reference fluid.
Reynolds number Ans: The ratio of inertial forces to viscous forces.
(How laminar and turbulent flow is)
ORP Ans: oxidation-reduction potential
Heatsink Ans: removes heat from electronic components
Fieldbus Ans: Serial - two way communication network
variable area flow meter Ans: maintains a constant differential pressure
and allows the flow area to change with flow rate.
What is the voltage drop across a diode? Ans: 0.7v
MAC address Ans: Media Access Control Address - machines physical
address
