A very stable, long lived, very high resolution pressure sensor is a critical enabling technology for DART's bottom pressure recorder. [11] It is a resonant quartz crystal strain gauge with a bourdon tube force collector. When compensated for temperature, this sensor has a pressure resolution of approximately 1mm of water when measuring ...
direct TPM sensor fitted in valve system, manufacturer VDO. In most current designs of direct TPMS, a small electronic assembly which is rugged enough to be mounted inside a tire, measures the pressure using a microelectromechanical system (MEMS) [1] pressure sensor and then transmits this and other information to one or more vehicle receivers.

In teaching technical geography, instructors often need to fall back on examples from human and physical geography to explain the theoretical concepts. [14] While technical geography mostly works with quantitative data, the techniques and technology can be applied to qualitative geography, differentiating it from quantitative geography. [1]
The standard method for measuring pore water pressure below the water table employs a piezometer, which measures the height to which a column of the liquid rises against gravity; i.e., the static pressure (or piezometric head) of groundwater at a specific depth. [6] Piezometers often employ electronic pressure transducers to provide
Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...
Gas expansion pycnometer is also known as constant volume gas pycnometer. The simplest type of gas pycnometer (due to its relative lack of moving parts) consists of two chambers, one (with a removable gas-tight lid) to hold the sample and a second chamber of fixed, known (via calibration) internal volume – referred to as the reference volume or added volume.
The simplest example of a stably stratified flow is an incompressible flow with density decreasing with height. [ citation needed ] In a compressible gas such as the atmosphere, the relevant measure is the vertical gradient of the entropy , which must increase with height for the flow to be stably stratified.
In fluid dynamics, hydrodynamic stability is the field which analyses the stability and the onset of instability of fluid flows. The study of hydrodynamic stability aims to find out if a given flow is stable or unstable, and if so, how these instabilities will cause the development of turbulence . [ 1 ]
