Define a type of sensor (and if applicable, state the transducer used within the sensor): HNC in Engineering Assignment, UCS, Ireland

1. Define a type of sensor (and if applicable, state the transducer used within the sensor) that can be used to measure the process parameters of the system as depicted in Figure 1 above.  The parameters to be measured are as follows:

a) Pressure at the top of the vessel
b) Flow rate in the upper and lower ducts
c) Temperature at the upper and lower ducts
d) Level in the pressuriser 

Then, describe how each of the defined sensors and transducers function.
(How does a change in the sensor's measured environment create a change in the sensor output?)

2.    Define the following process control signal terminology:

a) Accuracy
b) Precision
c) Hysteresis
d) Error
e) Repeatability
f) Reliability
g) Linearity

3.    For two of the sensors defined in task 1, explain the types of signal conversion or conditioning that may need to be considered to ensure that the sensor outputs are converted into suitable controller inputs. 
Appropriate standards must also be explained.

4    For each of the parameters in task 1, select one specific sensor and through research, critically review its suitability for the application stated in the brief.  You should consider the accuracy of and the environment that it will need to operate within.

(Clear evidence of research must be shown.)

5    For each of the sensors chosen in task 4, explore alternative industrial applications and give a clear example for each.
