Measurement:- :
The old measurement is used to tell usilength, weight and temperature are a change of these
physical measurement is the result of an opinion formed by one (or) more observes about the
relative size (or) intensity of some physical quantities,
Definition:
The word measurement is used to tell us the length, the weight, the temperature, the colour or a
change in one of these physical entities of a material. Measurement provides us with means for
describing the various physical and chemical parameters of materials in quantitative terms. For example
10cm length of and object implies that the object is 10 times as large as 1 cm; the unit employed in
expressing length.

Fundamental measuring process
These are two requirements which are to be satisfied to get good result from the measurement.
1. The standard must be accurately known and internationally accepted.
2. The apparatus and experimental procedure adopted for comparison must be provable.
Instrumentatio
Definition:
The human senses cannot provide exact quantitative information about the knowledge of events
occurring in our environments. The stringent requirements of precise and accurate measurements in the
technological fields have, therefore, led to the development of mechanical aids called instruments.
or
Definition: the technology of using instruments to measure and control physical and chemical
properties of materials is called instrumentation.
In the measuring and controlling instruments are combined so that measurements provide impulses
for remote automatic action, the result is called control system.
Uses:
-> study the function of different components and determine the cause of all functioning of the system,
to formulate certain empirical relations.
-> to test a product on materials for quality control.
-> to discover effective components.
-> to develop new theories.
-> monitor a data in the interest of health and safety.\
1. Direct and indirect measurement:
Measurement isa process of comparison of the physical quantity witra standard depending upon a
requirement and based upon the standard employed, these are the two basic methods of ea
measurement. ¢
Direct measurement:
‘The value of the physical parameter is determined by comparing it directly with
different standards. The physical standards like mass, length and time are measured by direct
Measurement.
Indirect measurement:
The value of the physical parameter is more generally determined by indirect
‘comparison with the secondary standards through calibration.
The measurement is convert into an analogous signal which subsequently process
and fed to the end device at present the result of measurement.
2. Primary and secondary & tertiary measurement:
The complexity of an instrument system depending upon measurement being made and
upon the accuracy level to which the measurement is needed. Based upon the complexity of the
measurementsystems, the measurement are generally grouped into three categories,
i. Primary
Secondary
ili. Tertiary. i
In the primary mode, the sought value of physical parameter is determined by comparing it
directly with reference standards the required information is obtained to sense of side and touch,
Examples are: as :
a) Matching of two lengths is determining the length of a object with ruler.
b) Estimation the temperature difference between the components of the container by inserting fingers.
c) Use of bean balance measure masses.
d) Measurement of time by counting a number of strokes of a block.
Secondary and tertiary measurement are the indirect measurements involving one
seconcat atremen ne measurements involving o'
transmission are called secondary measurements and those involving two convergent are called
tertiary measurements.
ee
Ex:
The convergent of pressure into displacement by means of be allows and the convergent of force
into displacement. .
Pressure measurement by manometer and the temperature measurement by mercury in glass
tube thermometer.The measurement of static Pressure by boundary tube pressure gauge is a typical example of tertiary
Measurement,
3. Contact and non-contact type of ‘Measurements;
i a
Contact type:
Non-contact type:
Where the sense doesn’t communicate physically with the medium.
Ex:
The optical, radioactive and some of the electrical/electronic ‘measurement belong to this category.
Objectives of instrumentation:-
1. The major objective of instrumentation is
safety and efficiency of the process
2. To achieve good quality.
3. To achieve auto machine and automatic control of process there by reducing human
4. To maintain the operation of the plan within the design exportations and to achieve good quantity
product.

1) Primary sensing element.
2) Variable conversion (or) Transducer element.
3) Manipulation of element.
4) Data transmission element.
5) Data processing element.11) PIMARY SENSING ELEMENT:
sn element thats sense to the measured variable The sensing element sense the conden @e
(or) value of the process variable by extracting a small part of energy from the measurement and State
produces an output which is proportional to the input, Because of the energy expansion, the mea
aoe 7 f yi su
quantity is always disturb. Good instruments are designed to minimise this loading effect.
2) Variable conversion (or) transducer element:
An element that converts the signal fr ic ther e lo
ignal from one physical for to An i i it i
an Mi ‘other without changing the informati
Example:
* Bourdon tube and bellows which transfer pressure into displacement,
* Proving ring and other elastic members which converts force into displacement.
Rack and Pinion: It converts rotary to linear and vice versa.
° Thermo couple which converts information about temperature difference to information in the
form of E.M.F.
3) MANIPULATION ELEMENT:
It modifies the direct signal by amplification, filtering etc., so that a desired output is produced.
[input] constant = Output
4) DATA TRANSMISSION ELEMENT:
An element that transmits the signal from one location to another without changing the information
content. Data may by transmitted over long distances (from one location to another) or short distances
(from a test centre to a nearby computer).
5) DATA PROCESSING ELEMENT:
An element that modifies data before it is displayed or finally recorded. Data processing may be used for
such purposes as:
Y Corrections to the measured physical variables to compensate for scaling, non-linearity, zero
offset, temperature error etc. iY Covert the data into useful
and torque developed,
form, e.g., calculation of engine efficiency from speed, Power input
'Y Collect int i
formation regarding average, Statistical and logarithmic values,
6) DATA PRESANTION ELEMENT:
An element that provides record or indication of the output from the data processing element. Ina

| signal aifiom the detector-transducer element’ is generally too small to operate an
rocorder and is amplification i necessary. Depending upon te type of transducer signa the
amplification device may be of mechanical, hydraulic/pneumatic, optical and electrical type.
ii Signal filtration to extract the desired information from extraneous data. Signal filtration removes the
unwanted noise signals that tend to obscure the transducer signal. Depending upon nature of the signal
and situation, one may use mechanical, pneumatic or electrical filters
ii, Signal modification to provide a digital signal from an analog signal or vice versa, or change the form
of output from voltage to frequency or from voltage to current.
\v, Data transmission to telemeter the data for remote reading and recording.
¢) Output stage:
which constitutes the data display record or control, The data presentation stage collects the output
from the signal;conditioning element and presents the same to be read or seen and noted by the
experimenter for analysis. This element may be of:-
visual display type such as the height of liquid in a manometer or the position of pointer on a
scale
Y numerical readout on an electrical instrument
Graphic record on some kind of paper chart or a magnetic tape.
