2. Task 1
Odometer :
An odometer or odograph is an instrument that
indicates distance traveled by a vehicle, such as a bicycle or
automobile. The device may be electronic, mechanical, or a
combination of electronical or mechanical. This function to
see velocity when bicyle or automobile running
Tripmeter :
Most modern cars include a trip meter (trip odometer).
Unlike the odometer, a trip meter is reset at any point in a
journey, making it possible to record the distance traveled in
any particular journey or part of a journey

5. Task 2
1. Accuracy : the different between when a measurement
reading true value when in measurement or result of
instrument lection is closed with the actually score from
measuring
2. Precision : Precision is the ability to produce the same
result from the repeated measurement and identical
measuring.
3. Range : absolute magnitude of a measurement of a
measuring instrument. Or the limit of measurement
values that an instrument is capable of reading. The
dimension being measured must fit inside range or
absolute magnitude of a measurement of measuring
instruments

6. 4. Subdivision : is an area or part of something that the
area itself is part of something bigger. Subdivision in
the measurement system is a smaller unit than the
other units are larger in the same process variables
5. Error : The actual difference between a measurement
value and the known standard value or amount of
deviation
6. Hysteresis : The delay between the action and reaction
of a measuring instrument. Hysteresis is the amount
of error that results when this action occurs.
7. Stability : The ability of a measuring instrument to
retain its calibration over a long period of time.
Stability determines an instrument's consistency over
time.

7. 8. Repeatability : The ability to obtain consistent results
when measuring the same part with the same
measuring instrument.
9. Sensitivity : the ability to detect the smallest changes
in the measurement instrument
10. Resolution : The smallest change in a measured value
that the instrument can detect. And resolution is also
known as sensitivity.
11. Thermocouple : a sensor for measuring temperature.
It consists of two dissimilar metals, joined together at
one end. When the junction of the two metals is
heated or cooled a voltage is produced that can be
correlated back to the temperature. The thermocouple
alloys are commonly available as wire.

8. The voltage produced is dependent on, but not
necessarily proportional to, the difference of
temperature of the junction to other parts of those
conductors. Thermocouples are a widely used type of
temperature sensor for measurement and control and
can also be used to convert a temperature gradient into
electricity.
12. RTD : sensors used to measure temperature by
correlating the resistance of the RTD element with
temperature and than RTD element is made from a
pure material whose resistance at various
temperatures has been documented. The material has
a predictable change in resistance as the temperature
changes; it is this predictable change that is used to
determine temperature.

9. 13. Pressure transmitter : used to make sure that no
machinery is building up pressure that is beyond levels
that are considered safe for the operators helps to
accomplish two specific goals. First, pressure
instruments monitor the amount of pressure applied
to a part of the process that is required in order to
achieve the desired result. Since the application of too
much or too little pressure may result in product that
cannot be sold, constant real-time measurements of
the pressurized environment is absolutely necessary.
14. Data logging : The process of using a computer to
collect data through sensors, analyze the data and save
and output the results of the collection and analysis.
Data logging also implies the control of how the
computer collects and analyzes the data.

10.  15. Valve : Mechanical or electromechanical device by
which the flow of a gas, liquid, slurry, or loose dry
material can be started, stopped, diverted, and/or
regulated.In general, can serve as an isolate valve,
switch, and control fluid flow in piping systems. In an
open valve, fluid flow direction from higher pressure
to lower pressure and than type or example valve

11. 16. ADC and DAC :
 ACD : (Analog digital converter) is a device that uses
sampling to convert a continuous quantity to a discrete
time representation in digital form. The reverse
operation is performed by a digital-to-analog converter
(DAC). An ADC may also provide an isolated
measurement such as an electronic device that
converts an input analog voltage or current to a digital
number proportional to the magnitude of the voltage
or current. However, some non-electronic or only
partially electronic devices, such as rotary encoders,
can also be considered ADCs.

12.  DAC : (Digital analog converter ) is a device that
converts a digital (usually binary) code to an analog
signal (current, voltage, or electric charge). An analog-
to-digital converter (ADC) performs the reverse
operation. Signals are easily stored and transmitted in
digital form, but a DAC is needed for the signal to be
recognized by human senses or other non-digital
systems. A common use of digital-to-analog converters
is generation of audio signals from digital information
in music players. Digital video signals are converted to
analog in televisions and cell phones to display colors
and shades. Digital-to-analog conversion can degrade
a signal, so conversion details are normally chosen so
that the errors are negligible.
