Even if there is no pressure differential between the inside and outside, the act of opening a door or forcing in a window pushes or pulls on the air in the car, creating a brief change in pressure. You can detect fluctuations in air pressure with an ordinary loudspeaker driver. A ...
How static pressure transmitter works? Static pressure transducers measure the pressure of a fluid when it is at rest. Static pressure transducers are the most commonly used pressure monitoring devices. When a fluid exerts pressure on the pressure transducers, the strain gage (or the sensor) with...
In order to measure the changes in resistance, the strain gauge must be connected to an electrical circuit that is capable of accurately responding to the changes and creating a differential voltage variation. Multiple strain gauges can be used in a divided bridge circuit that is called a Wheatst...
A differential pressure (DP) level sensor is shown in Figure 4. The essential measurement is the difference between total pressure at the bottom of the tank (hydrostatic head pressure of the fluid plus static pressure in the vessel) and the static or head pressure in the vessel. As with the...
3. Differential Pressure Transmitters, 4. Bubblers and 5. Displacersare all hydrostatic measurement devices. Any shift in temperature will consequently cause a change in the liquid’s specific gravity, as will pressure changes that affect the specific gravity of the vapor over the liquid. Both re...

The passage of gas through the meter creates a differential pressure between the two diaphragm chambers by compressing the one on the inlet side and expanding the one on the outlet side. This action alternately empties and fills the four chambers. The slide valves at the top of the meter ...

Another way to detect breaking glass, as well as somebody opening the door, is to measure the air pressure in the car. Even if there is no pressure differential between the inside and outside, the act of opening a door or forcing in a window pushes or pulls on the air in the ca...
