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 …
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 …

Understanding how to interpret a pressure switch’s instrument data sheet (gauge pressure, differential pressure, or absolute pressure) is critical for selecting, installing, and commissioning an EPC (Engineering, Procurement, and Construction) engineering project in industries such as oil, gas, and other process industries. The data sheet contains critical information regarding the specs, capabilities, and operating settings …

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, …
Process List few examples of Process Industries. Process Control Process control refers to the techniques used to regulate process variables during product manufacturing.For instance, the ratio of one ingredient to another, the material’s temperature, how well they are mixed, and the pressure at which they are held can all have a big impact on the …
What is a pressure gauge? A self-contained indication that converts the measured process pressure into the mechanical motion of a pointer is what is frequently represented by the word “pressure gauge.” An instrument for measuring the pressure of a fluid or gas in a system is a pressure gauge. Typically, it comprises of a circular …

What is Transducer? The non-electrical quantity is converted into an electrical form by using electrical method. The techniques like measurement, manipulation and control are done in transducer. The device when actuated, transforms energy from one form to another is called a transducer. Transducers classification: The transducer classifications shown are: Active & Passive Transducer: Active transducer …
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: …

What is an error in the pressure gauge? Inaccuracy in pressure gauge occurs when an output signal diverges from the desired value. When the pointer on the pressure gauge scale indicates a higher or lower value instead of actual. What are the factors affecting accuracy and performance in Pressure Gauges? The majority of pressure gauges …
