Process Instrumentation
What is engineering?
There are hundreds of answers to this question but according to me
the best answer is “IMPLEMENTATION OF APPLICATIONS” that what I have even
experienced.
When it
comes to technology I seriously believe that Instrumentation & Process
Control is one of the best technologies in today’s Industrial scenario.
Transducers & Controllers together can meet each and every requirements of
an automation system whether it is automation of a Corporate Building or process
of any manufacturing industry whether it is a Direct Digital Controller (DDC),
Programmable Logic Controller (PLC) or a Distributed Control System (DCS).
Instrumentation:
Instrumentation is nothing but a branch of Science or Technology that deals
with calibration, scaling and measurement of physical parameters. Now, if we
are talking about the physical parameter then what type of physical parameters?
There are number of physical parameters such as temperature, pressure, flow,
position, RH etc. These are some of those parameters which can effect the result
of any automation system. Hence, instruments play a vital role in order to
monitor them and minimize them because an instrument is a device that is used
to measure the parameters and deliver instruction to the controller to control
it. There are number of instruments involved in industrial process. But
specifically I want give light on a special type Transducers.
What is a
transducer? Basically, a transducer is a device that converts one form of
energy into another. As we know that energy can neither be created nor be
destroyed it can only be converted from one form to another.
But due to certain
exceptions, in Instrumentation Engineering a transducer is always defined as a
device that converts any energy into Electrical form. The most commonly used
transducers are sensors. A Sensor is a device that converts the physical
parameters as discussed earlier into electrical signal. Now a question arise!
what is the difference between a sensor and a transducer? The answer is very
simple, a sensor is always a transducer whereas a transducer may or may not be
a sensor. Sensor is a classification of transducer.
In case of temperature
measurement which is a serious parameter when it comes to machineries. In that
case we use different types of temperature sensors such as Resistance
Temperature Detector which is most widely used in industries. There are some
other sensors such as Thermocouple,
Thermistors, Thermopiles etc. are also used
for different temperature ranges. For higher temperature of almost 4000 degree
Celsius Pyrometers can be used. It may be either an optical or a radiation
Pyrometer. Similarly for other parameters such as position detection i.e. whether a metallic or a non metallic material
is present or not, Proximity Sensors of different types are used. For measurement of the flow rate
flow meters such as Orifice, Nozzle, Venturimeter, Pitot Tube etc. are used.
Hence in order to run the production process, packaging process of any industry
or managing energy, safety and security, utility monitoring in industry or to
monitor any infrastructure like Metros, Hospitals or any Corporate building instruments play a vital role. In the current
industrial scenario number of technologies is integrated to provide utility in
which instruments play a vital role
