1738 — Daniel Bernoulli asserted in Hydrodynamica the principle that as the speed of a moving fluid increases, the pressure within the fluid decreases. ( Kinetic theory ) 1742 — Anders Celsius proposed a temperature scale in which 100 represented the temperature of melting ice and 0 represented the boiling point of water at 25 inches and 3 ...
Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area.
A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix piezo- is Greek for 'press' or 'squeeze'.

A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
Since 1961 the company started the in-house production of charge amplifiers and the development of other sensors. The company made several major innovations, some of which would be put to use in the Apollo manned spaceflights, [citation needed] and became a world leader in the development of quartz sensors. Walter Kistler left the company in ...
Direct TPMS (dTPMS) directly measures tire pressure using hardware sensors. In each wheel, most often on the inside of the valve, there is a battery-driven pressure sensor which transfers pressure information to a central control unit which reports it to the vehicle's onboard computer.
The pressure differential is typically measured using diaphragm pressure transducers with digital readout. Since these meters have significantly lower permanent pressure losses than orifice meters, Dall tubes are widely used for measuring the flow rate of large pipeworks.
