Pressure sensors

-


Pressure sensor is also termed as pressure transducer or pressure switch. Depending upon the type of output interface ,pressure sensors are classified as analogue and digital .


Different kinds of pressure sensors used in some popular applications are :

1. Industrial . Gases and pressures in industrial units , for example , in the chemistry industry , are precisely monitored and controlled using pressure sensors. These are also board - level pressure sensors, normally mounted on PCBs , that are used to measure the pressure of gases or liquids.


2. Computing . Many computers and smartphones have touchscreen display with pressure sensors. Whenever pressure is applied on touchscreen , the sensor determines the point of application and accordingly generates an electric signal that informs the processor to take further actions.


3. Automotive . In automotive industry , pressure sensors monitor the oil and coolant pressure and regulate the power. Pressure sensors constitute part of the anti - lock braking system. 


4. Medical . Pressure sensors are used in digital blood pressure monitors and ventilators to optimise these according to patient's health and requirements.


5. Marine . Pressure sensors are used in ships and submarines to estimate the depth at which these are operating and for detailing the marine conditions so that the electronic systems stay safe . 


6. Aviation . In airplanes, pressure sensors maintain a balance between the atmospheric pressure and control systems of the airplane. These are not only protect the various internal components of the airplane but also give exact data about the external environment .

Hand energy generate clean energy with the power of your  body , so no need to plug in your phone or gadgets and wait till it charge , now you can charge your gadget anywhere anytime without electricity. As we know that low battery means we are disconnected from the world, and sometimes there is no way to charge your gadgets when you need it most. Now you forgot about this problem  because you would always have your own generator with you. With the help of Hand energy you can generate your own clean energy with the power of your body and store it . It will always keep it with you and charge your devices wherever you are. Working : Firstly start the Hand energy by winding the starter ring. Release the starter ring, that will transmit an impulse to the rotor. Now rotate your Hand energy with your wrist to keep the rotor spinning. Average speed of rotor is 5000 rpm . The magnetic rotor transmit mechanical power to the stater and produce and electric current , charging th

VH - 80 : World's first Bilateral laser measurer

-
Image
VH - 80 is the world's first bilateral laser measuring device. It shoots two pulses of the laser light from two sources in opposite directions and measure the amount of time it takes from each pulses to bounce back to its sensors, as light moves at a constant speed , it can calculate the distance between itself and the targets with high accuracy. It works similarly as Sonar works for submarine under sea level. You can measure the distance between two points by positioning yourself anywhere along the line of measurement. Two laser diodes can take three measurements per single action: left , right and total combination. You can save significant time by effectively reducing your needs to travel to various references points required by one directional devices. By acquiring two values in a row, it can quickly calculate the area of your space Application: When you make measurements , we usually need to do it more than once , but it has an internal memory t
