Microprocessor based instrumentation

I. Introduction

There are assorted applications of microprocessor which makes our life easy and simple. Assorted instruments which we are utilizing in our twenty-four hours to twenty-four hours life includes the function of microprocessors, which is reasonably called as Microprocessor Based Instrumentation. On the footing of its processing and intelligence microprocessor are base for the operation of assorted instruments. Here is the description of some devices or instruments which uses microprocessors. Even the most common intent equipments which are in our usage such as toothbrush, thermometer etc. Puting an embedded microprocessor system into a merchandise makes the merchandise smart. It can so be programmed to make things that are excessively hard or expensive utilizing conventional engineerings such as logic, or clip switches, and so on. Link such a smart merchandise to the Internet and it can make even more. For illustration, merchandises can be programmed to make self-diagnostic cheques and to describe back to the maker. Not merely does this supply the possible to roll up informations that can be used to better merchandises, it can besides let for the maker to inform the user of possible jobs, so that action can be taken. This opens up possibilities for improved client service every bit good as new services. Basically, embedded microprocessors enable houses to vie on merchandise and service invention, by adding merchandise and service characteristics that clients value.


An atmospheric ion counter was modified and fabricated to mensurate the atmospheric ions. The bias electromotive force of ion counter was adjusted utilizing microprocessor and stepper motor. With the accommodation of bias electromotive force and flow rate of air the instrument, the instrument is capable of mensurating ions of all the three classs i.e. little ions, intermediate ions and big ions.

III. Energy Efficient Sterilization for Surgical Instrument

A microprocessor based wireless frequence operated initiation heated sterilisation works is proposed in this article. In this works heat is straight generated in surgical chromium steel steel Instruments by agencies of eddy current flow. With the accommodation of pulse width transition ( PWM ) controlled technique, the controlled heat is generated as per the medical norms. By commanding pulse width it can make at degree of temperature upto 240 grade centigrade. This is sufficient to sterilise the infirmary equipment. The deepness of heat incursion by initiation heating procedure will depend upon the frequence coevals. The relation is inversely relative with the frequence. For sterilisation procedure, surface country of the instrument must be heated through H2O boiling in bing procedure. A new coevals initiation heated sterilisation works is proposed for the dry surface warming in topographic point of conventional a few parallel chromium steel steel home bases may be added with

the surgical instruments under H2O to accomplish the same aim. In this proposed strategy, there is no heat conductivity loss in between beginning of heat and object ( operational instruments ) . It offers an alone award as there is no daze jeopardy during handling of poached chromium steel steel surgical instruments. Microprocessor control is introduced for choosing slow or speedy heat rate. Microprocessor assembly level linguistic communication gives flexibleness to plan the heat rate alteration with regard of clip without rearranging the hardware circuitry. Besides it control the temperature through a transducer with the aid of closed cringle control.

IV. Portable 4-Channel Gamma Ray Spectrometer

It is compact, rugged, lightweight spectrometer and comprises of a 8085 microprocessor, standard peripherals and a scintillation sensor of size 1.75” ten 2” . It is used for insitu measuring of gross counts, and radioelement concentrations of U ( U ) , Th ( Th ) , and K ( K ) with LCD alpha numeral show. The device is indigenously designed and fabricated.

V. Borehole Logging System

Microprocessor-based gamma-ray spectral logging with scintillation sensor to follow the parallel profiles of entire, K, U and Th channels with matching deepness. This system is being tested in the field in different countries for its public presentation.

VI. Microprocessor Based Bulk Ore Analyser

It contains 6 scintillation sensors to calculate the class of the ore in % eU3O8 carried in 25-ton dump truck from mine. It was designed and fabricated for UCIL.

VII. Wind Speed Instrumentation System

This system is a basic system to mensurate the air current parametric quantities like wind velocity for air current velocity, a ocular indicant of air current velocity is obtained by dc generator to dc voltmeter with appropriate calibrated graduated table. The graduated table needs to be arranged such that the arrow indicates a velocity of 1milepersecond when the generator stalled and electromotive force is zero. Then any velocities above 1 mile / second will be right displayed if the graduated table is calibrated harmonizing to given graph of frequence poetries end product electromotive forces. Our circuit design works with a truth of 1 mile / second and best suited for analyzing highs between 30 and 100 m Both wind parametric quantities are measured utilizing microprocessor based instrumentality system. By pressing a several cardinal several parametric quantities can be measured for which interrupt service modus operandi is used.

VIII. Other Instruments

  1. Portable audio-visual scintillometer.
  2. Carborne gamma study system ( microprocessor-based ) for entire, K, U and Th.
  3. Light weight mine face scanner with beta-sensitive Geiger Muller ( GM ) tubing.


No uncertainty, In this epoch everything is modernized, everything is operated under the computing machine i.e. microprocessors. From toothbrush to missiles everything is operated with microprocessor control. It is supposed that in close hereafter the autos will be to the full automated and can be operated under microcontroller applications. Cars will be parked itself, will be driven automatically, itself control its velocity harmonizing to traffic and many more.

Microprocessor are progressively playing a major function in modern society. The “ unseeable ” 1s, used for commanding and supervising machine tools, autos, aircraft, consumer electronics and other equipment are the most legion. They are bit by bit altering the relationship we have with these devices. It is interesting to demo that this is a “ market-pull ” instead than a “ technology-push ” phenomenon. The design of new french friess therefore represents a uninterrupted challenge for the applied scientists and engineers endeavoring to give the market the merchandises it requires, and which are by and large planned a long clip before they really appear. Monolithic microprocessor are catching all sorts of computing machines. Minicomputer lines were absorbed during the 80 ‘s, main-frame lines during the 90 ‘s and likely super-computers by the beginning of the following century. During this extraordinary development, these devices have used all the proficient inventions which had been conceived for the old coevalss of computing machines. The hereafter of these devices is really ambitious. To maintain the evolutionary rate of calculating power and binary codification compatibility, wholly new executing techniques will necessitate to be invented, finally taking to the break-down of the physical quantum barrier around 2010.
