Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure. Pressure sensors are devices that read changes in pressure, and relay this data to recorders or switches. They are commonly used in safety devices such as safety mats, edges and bumpers to actuate shut-off switches. Other pressure devices include transducers, transmitters, elements, indicators, gauges (bellows, bourdon tubes, capsule elements and diaphragm elements) and controllers.

There are five main pressure sensor types: absolute, gauge, vacuum, differential and sealed.  Each of these sensors measures different pressure variables.  The first of these sensor types are absolute sensors.  These devices test for absolute pressure, which is a measurement of pressure, relative to a perfect vacuum.  Gauge sensors are the most common type of pressure sensors.  They can be calibrated to measure pressure with respect to atmospheric pressure at a given location.  Vacuum sensors are used in situations where the pressure level that is being tested for, is lower than the localized atmospheric pressure.  Differential pressure is measured by reading the difference between the input of two or more pressure levels.  Finally, sealed gauged sensors measure pressure relative to one atmosphere at sea level (14.7 PSI) regardless of local atmospheric pressure.


Products & Services Related to Pressure Sensors
Analog Pressure Gauges
Analog pressure gauges are mechanical devices that include bellows, Bourdon tubes, capsule elements and diaphragm element gauges.
Digital Pressure Gauges
Digital pressure gauges use electronic components to convert applied pressure into usable signals. The gauge readout has a digital numerical display.
Pressure Gauges
Pressure gauges are used for a variety of industrial and application-specific pressure monitoring applications.  Uses include visual monitoring of air and gas pressure for compressors, vacuum equipment, process lines and specialty tank applications such as medical gas cylinders and fire extinguishers.
Pressure Instruments
Pressure instruments are used to measure, monitor, record, transmit or control pressure.
Pressure Switches
Pressure switches are actuated by a change in the pressure of a liquid or gas.  They activate electromechanical or solid-state switches upon reaching a specific pressure level.
Pressure Transmitters
Pressure transmitters translate the low level output of a sensor or transducer to a higher level signal suitable for transmission to a site where it can be further processed. These devices include pressure sensors, transducers, elements, and instruments.
Vacuum Sensors
Vacuum sensors are devices for measuring vacuum or sub-atmospheric pressures.
