Temperature measurement techniques

Temperature measurement is another important variable in any process industry. There have been several measuring techniques implemented in order to accurately measure this variable. These different techniques makes use of a variety of devices for measuring temperature. One of the most devices used from centuries till this day have been associated with fluids (like mercury or alcohol). The sole property of fluids to expand during high temperatures and vice versa, is the main reason for this association. However, there are some other instruments/devices which came to used at a later stage; namely, thermocouples, thermostats and resistive temperature devices (RTD) etc.

Level and some of basic level measurement techniques

     After a few days of interval, starting with this post, in this article I'm about to decipher the basics of level and level measurement. Accurately measuring volume of  fluid in containers, continuously has always been a challenge in industries specially dealing with hazard environment, where the fluid could be acidic and/or may be maintained in high temperature/pressure. Considering these facts lets proceed to the article.

Some More Pressure Sensing Elements

     Most of the time the pressure to be measured and transmitted are built around the capsule concept, as seen in the previous blog-post. The capsules were capable of measuring mostly differential pressure (i.e., the difference between the high pressure input and the low pressure input) and thus they were called as differential pressure transmitter (DP Transmitter) or  DP cells.

Pressure And Sensing Elements

     In this post i'll try to cover the basics of pressure and the various principles associated with it. Pressure is probably most common measured variable in any industrial plant. it includes the measurement of steam pressure, feed water pressure, lubricating oil pressure, condenser pressure and many more.

Basics Of Instrumentation [Definitions]

This is my first post towards this blog, and being a student of this stream I've learnt that there is no question as silly or meaningless, bearing this in mind I'll try to cover every possible question dealing with instrumentation and its counter-parts.
