With the rise in smart watches and navigation systems, absolute pressure sensors find homes wherever elevation above sea level (altimeter measurement) is required. Weather stations also use them for barometric pressure measurements.

Physical separation from hazardous media: Fluid-isolation barrier can be implemented to prevent corrosive media coming into direct contact with the sensor diaphragm; Heat is dissipated from the media in the tube.

Industrial pressure sensors also referred to as pressure transducers, pressure transmitters, pressure indicators and pressure switches, normally have a diaphragm type design that uses strain gauges, which are either bonded to or diffused into it, with the strain gauges acting as resistive elements.

Terms of pressure sensor, pressure transducer and pressure transmitter are somewhat interchangeable in the industrial world. Pressure sensors can be described with a 4-20mA output signal and pressure transducers with a millivolt signal.
