Assuming we are using a pressure transducer to measure barometric pressure, I understand that a gauge type transducer would be used. The internal diaphragm would have a fixed pressure behind it (at a guess would be at standard temp/pressure, STP, ie 20 deg C @ 1013mb), so the transducer has a reference to work against. The front of the diaphragm would be exposed to atmosphere. I would assume the reference (gauge) pressure would vary as the barometric pressure varies, as the diaphragm would move towards the side with least pressure, or at 1013mb the diapragm would be in the centre (which could be used as the null output voltage), higher than 1013mb could produce a positive voltage swing, less than 1013mb could go negative. This is all I can think of, please let me know if on the right track.

Does barometric pressure go up or down in tornadoes?
Barometric pressure goes down in a tornado.
What is 0 bar pressure?
A barometric pressure of zero is a vacuum.
What is the barometric pressure in Rio?
Barometric pressure (also known as atmospheric pressure) is the force exerted by the atmosphere at a given point. It is known as the "weight of the air". A barometer measures barometric pressure. Measurement of barometric pressure can be expressed in millibars(mb) or in inches or millimeters of mercury (Hg). Normal pressure at sea level is 1013.3 millibars or 29.92 inches of mercury. Fluctuations in barometric pressure are usually a sign of weather conditions. A rise in pressure usually means improving weather while falling pressure may reflect impending inclement weather. Barometric pressures will also vary with altitude and moisture.Barometric pressure in rio is 29.78 in hg and still rising
Do changes in the barometric pressure make you tired?
no
Why pressure gauge is called a gauge not a meter?
Because Pressure gauge measures the the differenceof pressure so it is called pressure gauge not meter.
Can the barometric pressure affect how may sides a snowflake has?
no
How does temperature affect an air traffic controllers operations?
The barometric pressure is what pilots use to gauge their altitude, however, all pilots above flight level 180 use 29.92. Barometric pressure is related to temperature changes, especially in higher altitude and mountainous areas.
What change will not affect the pressure in a container?
The volume of the container is increased.
What causes barometric pressure?
Barometric pressure measures the weight of the air.
How are blood pressure and barometric pressure associated?
blood vessels constrict according to barometric pressure
What causes increases in barometric pressures?
Low and high pressure systems. Obviously if you have a Low pressure system the barometric pressure will get low. High pressure causes the barometric pressure to rise.
What happens when barometric pressure increases?
When the barometric pressure rises it means calm fair weather is coming or is already occurring. When the barometric pressure falls it means foul weather is on the way such as rain and storms and clouds.
The center of a hurricane is characterized by very low what?
A hurricane has very low barometric pressure.
Does barometric pressure go up or down in tornadoes?
Barometric pressure goes down in a tornado.
An altimeter is an adaptation of the?
The altimeter is basically a specialized pressure gauge. It measures the pressure of the column of air above it. As the altitude varies, the air column height varies, which registers on the altimeter. Since the air pressure also varies with changes in the barometric pressure, altimeters must have an adjustment to compensate for changes in local barometric pressure.
What does sudden decreases in barometric pressure indicate?
A sudden decrease in barometric pressure is a sign that a storm is coming.
Is barometric pressure the same as atmosheric pressure?
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.
