1. the purpose of a frequency meter ANS >> indicate the frequency of the power being induced
2. the prevent freezing of an industrial firewater system a safe rule to follow is
ensuring the top of the pipe is burried not less than below the lowest
frost line ANS >> 0.3m
3. on/off control the final control element is either positive or negitive-
ANS >> 100%, 100%
4. some characteristics of the series DC motor include ANS >> small current at no load
conditions danger of overspeed if the load is removed
the load current equals the exitation current
5. advantage of a panel mounted alarm annunciator over computer moniter
displays ANS >> operator can quickly recognize an alarm by its location on the panel without scrolling
6. is often the first indication of a fire so automatic dectectors should be
used ANS >> smoke

,7. controlling the identified indirect cause of workplace accidents or incidents
is normally long term development process involving measures or system
changes ANS >> preventitive
8. CSA-b51 a pressure vessel installed in a closed hot water system or cooling
system provided a pneumatic cushion or the expansion of water is called
ANS >> a cushion tank
9. iron or constantan ca be used in a thermocouple to measure a temp range
of ANS >> -210 to 1200
10. difference between the set point and the actual procces variable is known as
offset and is a charecteristic of controllers ANS >> Proportional only
11. if an generator looses exitation the rotor accelerates and it operates as an
induction generator running above speed ANS >> synchronous, synchronous
12. a double seated balance valve could be described as ANS >> passing up to twice as
much fluid as a single port valve, it generally divides the flow in half through to control ports
