How does a Bourdon tube gauge work?

Introduction  Bourdon tube uses a coiled tube which as it expands due to pressure increase causes a rotation of an arm connected to the tube Working principle The pressure sensing element is a closed coiled tube connected to the chamber or pipe in which pressure is to be sensed. As the gauge pressure increases the tube will tend …

Pressure Measurement – Bourdon Gauge -Working Principle Advantages and Disadvantaged

Working Principle Of Bourdon Gauge  If a tube having oval cross section is subjected to pressure its cross section tends to change from oval to circular. Construction of a Bordon Gauge  Bourdon tube gauges consist of a circular tube. One end of the tube is fixed while the other end is free to undergo elastic deformation under …

Introduction to Industrial Instrumentation

What is Instrumentation?          Instrumentation is the art and science of measuring and control. The relevant process information [indication, trends, or status] is made available at a predetermined location in a predetermined manner. Moreover, it regulates the parameter within or at a set value. Instrumentation gives the plant operator the tools they need to run the facility safely, …

300+ Instrumentation Engineering Interview Questions – Part 2

1. What is RTD? RTDs (Resistance Temperature Detector) are temperature detectors whose resistance changes as the temperature rises. RTDs are used for continuous temperature measurement and have a positive temperature coefficient. When the temperature rises, the resistance of the RTD decreases. Advantages of RTD: 1). More accurate 2). Linear output 3). High sensitivity Disadvantages of RTD: …
