What is the name of the pressure measuring device?

In general, a device for measuring pressure is called a manometer. In which areas are the manometers used and what is measured?

• The barometer is a device that measures atmospheric pressure, expressed in the force of the pressure of air molecules on the surface of the Earth as a result of the influence of gravity.
• Sphygmomanometer or tonometer - this devicemeasures blood pressure in a person. The principle of operation is simple: the air is pumped into the device with a pipette. The fabric that clasps the arm expands and clamps the limb. In these conditions, the pulse is listened very clearly, which allows the doctor to draw his conclusions about the condition of the subject.
• Pressure sensors are actively used onproduction and in steam engines. With increasing pressure, the physical properties of the sensors also change, which allows them to send the necessary information about the operation, for example, of a steam boiler to the production control panel.
