Flow Measurement (Mechanical Transducers): The measurement of flow rate and quantity is the oldest of all measurements of process variables in the field of instrumentation. It is used to determine…
Pyrometer Working Principle: When temperature being measured is very high and physical contact with the medium to be measured is impossible or impractical, optical pyrometer based on the principle of…
What is a Temperature Transducer?: Temperature Transducer is one of the most widely measured and controlled variable in industry, as a lot of products during manufacturing requires controlled temperature at…
Photoelectric Transducer Working Principle: Photoelectric Transducer can be categorized as photo emissive, photo-conductive or photo-voltaic. In photo emissive devices, radiation falling on a cathode causes electrons to be emitted from…
Capacitive Pressure Transducer Working Principle: Capacitive Pressure Transducer Working Principle - A linear change in capacitance with changes in the physical position of the moving element may be used to…
Pressure Inductive Transducer: Pressure Inductive Transducer - A simple, arrangement, wherein a change in the inductance of a sensing element is produced by a pressure change, is given in Fig.…
Linear Variable Differential Transformer (LVDT): The differential transformer is a passive inductive transformer. It is also known as a Linear Variable Differential Transformer (LVDT). The basic construction is as shown…
Electrical Transducer: A transducer is defined as a device that receives energy from one system and transmits it to another, often in a different form. Broadly defined, the transducer is…
