Pressure Sensor

As-Salaam-Alaikum, Welcome to my blogger "World of Knowledge".Here we discuss the topic Hall Effect Sensors.

Points to be discuss in this Article are given below :
  • Pressure Sensor
  • Uses of Pressure Sensor
  • Physical Principle of Pressure Sensing
  • Absolute & Differential
  • Application of Pressure Sensor
Pressure Sensor:


A pressure sensor measures pressure typically of gases or liquids.
Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area.A pressure sensor usually acts as a transducer, it generates a signal as a function of the pressure imposed.

Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names.

Uses of Pressure Sensor:

Pressure sensors are used for control and monitoring in thousands of everyday applications.Pressure sensors can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude.

Pressure Sensor

Physical Principle of Pressure Sensing: 

  • Static Pressure: defined as the force exerted perpendicularly on a unit area.




  •    Volume Pressure: defined as mass per unit volume.
  • Liquid pressure: e.g a person lies inside the bathtub.




Pressure sensor consist of,

Absolute: 

A Sensor That Measures Input Pressure in Relation to a Zero Pressure.Can be used to Calculate Altitude.

Differential:


A Sensor That Is Designed to Accept Simultaneously Two Independent Pressure Sources.  The Output Is Proportional to the Difference Between the Two Sources. Can be used to Calculate Indicated Airspeed.

Applications of Pressure sensors:

  • Touch screen devices
  • Automotive industry
  • Biomedical
  • Aviation
  • Marine industry

As-Salaam- Alaikum,   Welcome to my blogger "World of Knowledge".Here we discuss  the topic Motion Sensors. Points to be discuss in this Article are given below  : Motion Sensor Technological Concept  Advantage & Disadvantage Motion Sensor: A  motion sensor  (or  motion detector ) is the linchpin of your security system, because it's the main device that detects when someone is in your home when they shouldn't be. A  motion sensor  uses one or multiple technologies to detect movement in an area Motion sensors improved in World War II. First use of motion sensor in the 1940s was by Samuel Bagno. Used to determine location of a person within a room. And then used to calculate the movement of the stars. The first use in World War II with mine. Mines placed below the ground would explode when it sense movement on the surface. In modern technology it is used in Radar to track enemy. Helps in air traffic control to avoi...

What is Transformer,Its Working Principle and Constructions

Image
What is Transformer? A device that transfers electrical energy from one circuit to another through the process of   electromagnetic induction . Figure 1 Working Principle of Transformer: The principle of mutual induction states that when two coils are inductively coupled and if current in one coil changed uniformly than an emf induced in the other coil. This emf can drive a current, when a closed path is provided to it. The transformer work on the same principle.  It consist of two inductive coils which are electrically separated but linked through a common magnetic circuit. Both these coils are high mutual inductance. One of two coils are connected to a source of alternating voltage. The coil in which electrical energy is fed with help of source is called primary winding and the electrical energy is transformed to this winding is drawn out to a load. This winding is secondary winding and it is connected to a load. N1 is number of turns of primary windin...
