Pressure Sensor | How Does a Pressure Sensor Work?
A pressure sensor is an instrument consisting of a pressure sensitive element to work out the particular pressure applied to the device (using completely different operating principles) and a few elements to convert this information into an output signal. Technologies Used inside Pressure Sensors Strain gauge based mostly pressure sensors: It conjointly use a pressure sensitive component wherever metal strain gauges area unit affixed on or skinny film gauges area unit applied on by sputtering. This measurement component will either be a diaphragm or for metal foil gauges measurement bodies in can-type may be used. The large blessings of this monolithic can-type design are an improved rigidity and the capability to measure highest pressures of up to 15,000 bar. Capacitive pressure sensors: Its use a pressure cavity and diaphragm to supply a variable capacitance. The diaphragm is ill-shapen once pressure is applied and capacitance decreases consequently. This variation in capability is measured electrically and is then set in relevance the applied pressure. These sensors area unit restricted to low pressures of roughly 40 bar. Piezo-resistive pressure sensors: Its include a diaphragm – largely product of semiconducting material – with integrated strain gauges to discover strain as a results of applied pressure. These strain gauges area unit usually organized in a very bridge circuit circuit to cut back sensitivity and increase the output. Because of the fabric being employed the pressure limitation is at around 1,000 bar. Competitive Landscape: Some of the major Companies in the Pressure Sensor Market are Panasonic Corporation, ABB Ltd, Bosch, Analog Devices Inc., Honeywell International, Delphi Automotive PLC, Infineon Technologies, Emerson Process Management, Freescale Semiconductor, and Freescale Semiconductor Ltd. Trends in Pressure Sensor Market: The Global Pressure Sensor Market is expected to grow at a CAGR of 5.5% during the forecast period (2019–2026) to attain a value USD 11.92 billion by 2026.
