Pressure sensors are omnipresent in our daily lives and play a crucial role in various industries. Whether measuring atmospheric pressure, monitoring hydraulic systems or optimizing the fuel efficiency of cars, these devices are essential.
Kheeos, your specialist in industrial spare parts, offers you its range of pressure sensors and also discover our entire range of sensors & transducers.
A pressure sensor transforms physical pressure into a measurable electrical signal. Most sensors use sensitive elements which transform this pressure with great precision. The techniques used vary and depend on the type of sensor used.
Piezoelectric sensors exploit the properties of piezoelectric materials to convert mechanical pressure into an electrical charge. When a force is applied to the piezoelectric material (such as quartz or certain ceramics), it generates a voltage proportional to the pressure exerted. This type of sensor is particularly appreciated for its reliability and rapid response.
Capacitive sensors use an elastic diaphragm that deforms under pressure. This deformation modifies the capacitance between two conductive plates located on either side of the diaphragm. The change in capacity can be measured and translated into a pressure value. These sensors are often used for their increased sensitivity and accuracy.
Strain gauge sensors are based on the deformation of an elastic support to which strain gauges are stuck. Under the effect of pressure, the support deforms, thus modifying the electrical resistance of the gauges. These variations can then be converted into an electrical signal proportional to the pressure. They are used in particular in aggressive environments thanks to their robustness.
Piezoresistive sensors incorporate silicon resistors whose value changes depending on pressure-induced deformation. These variations are then amplified and translated into usable data. Known for their high linearity and wide measurement range, they are commonly used in areas such as the automotive and aerospace industries.
In the automotive industry, pressure sensors are essential for the proper functioning of many systems, such as engines, brakes and transmissions. In particular, they make it possible to regulate tire pressure, optimize combustion in injection engines and monitor assisted braking systems.
Aeronautics and aerospace impose strict requirements in terms of reliability and precision. Pressure sensors are used to measure atmospheric pressure at different altitudes, manage cabin pressurization systems and control aircraft engines. Silicon piezoresistive sensors are often preferred for their performance in these extreme situations.
Sensors also play an essential role in the medical field. They are integrated into various devices, such as blood pressure monitors for measuring blood pressure, respiratory equipment to monitor pressure in the lungs and infusion pumps to deliver medications precisely. In this context, capacitive technology is frequently used for its sensitivity and security.
Industrial applications of pressure sensors cover a wide range of sectors, from chemical processes to hydraulic systems. They are used to monitor pressure in pipelines, ensure the safety of chemical reactors, and regulate hydraulic machines. Strain gauge sensors are often preferred in these environments for their durability and accuracy.
Finally, sensors are also entering the consumer electronics sector, where they are present in smartwatches to track blood pressure or even in cell phones to determine altitude via barometric pressure. The miniaturization and reduced energy consumption of these sensors constitute a major advantage in this industry.
Thanks to its technical expertise and its commitment to customer satisfaction, kheoos market positions itself as a partner of choice for the selection of pressure sensors meeting the highest standards of performance and reliability.
