What are Pressure Sensors? Pressure sensors are devices that sense the applied pressure of gases or liquids. The output of the measurement is then converted into an electrical signal which reflects the amount of pressure applied. You can find out more on our useful <a href="https://uk.rs-online.com/web/content/discovery/ideas-and-advice/pressure-sensors-guide" target="_blank">pressure sensors guide</a>.There are various sensor technologies used within pressure sensor devices. Depending on the measurement requirements, this can influence their sensing accuracy and reliability. The mechanical displacement within the sensor is turned into an electrical output signal which is achieved with 5 different methods.<ul><li>Resistive Sensors - These types of sensors use the change in electrical resistance of a strain gauge connected to the diaphragm.</li><li>Capacitive Sensors - Are highly sensitive and are able to measure low pressure under 10 bar while still withstanding large overloads.</li><li>Piezoelectric Sensors - These sensors use substances like Quartz to generate a charge on the surface when pressure is applied. Piezoelectric pressure sensors are ideal for measuring fast changing pressures.</li><li>Optical Sensors - These use interferometry to measure pressure changes in optical fibre. They are not disturbed by EMI and can be used in noisy or medical environments.</li><li>MEMS – Short for micro-electro-mechanical system and contains capacitive or piezo pressure sensing mechanisms on silicon at micron level resolution.</li></ul>Types of Pressure SensorsThere are various properties which can be used to classify the type of sensor it is and its appropriate application, including; what pressure range they measure, their operating temperature range or the pressure type they measure.<ul><li>Absolute Pressure Sensor - This type of sensor measures pressure relative to the perfect vacuum (zero reference point).</li><li>Gauge Pressure Sensors - These are often used to measure atmospheric pressure and are sometimes referred to as relative pressure sensors.</li><li>Sealed Gauge Pressure Sensors - Similar to gauge pressure sensors except they measure pressure relative to a fixed pressure, not the current ambient atmospheric pressure which can vary.</li><li><a href="https://uk.rs-online.com/web/c/automation-control-gear/sensors/pressure-sensors/?applied-dimensions=4294572451" target="_blank">Differential Pressure Sensors</a> - These can be used to measure the difference between two different pressures (differential pressure) which can be connected to either side of the sensor. They are often used to measure pressure drops, fluid levels and flow rates.</li></ul>Pressure Sensor ApplicationsPressure sensors are used in a wide variety of applications across many industries. These include medical, aviation, automotive and marine. Take a look at our comprehensive range of pressure sensors, many brought to you from industry leading brands including our very own, RS Pro.

They work by detecting changes in pressure, which then causes a physical reaction in the sensing element of the device. This output is then translated into an electrical signal. Two commonly used main types are pneumatic sensors, which are used with air and gas applications, and hydraulic, which are used with water and fluids.They can be used for a broad range of pressure measuring purposes in industrial or scientific areas such as checking the applied pressure of mediums in tanks and systems, monitoring liquid levels, tracking pressure changes between separate locations.The 24PC/26PC series models by Honeywell are miniature SMT (surface mount technology) low-pressure sensors which are ideal for use with wet or wet differential sensing. Due to their compact size they are a great space saving solution for your installation. These devices use a specialised piezo-resistive micro-machined sensing element, ensuring high performance and accuracy. They are are designed to measure ±1 to ±15 psi (over an operating temperature range of -40 to 85 ºC) .The PX3 series heavy duty pressure transducers use piezoresistive sensing technology with ASIC (Application Specific Integrated Circuit) signal conditioning. These devices feature a rapid response time of less than 2 ms. They also offer environmental protection up to IP67 for high resistance against water/particle ingress and are perfect for use in challenging industrial installations. They use tough brass housing which is corrosion resistant, for optimal longevity.Honeywell sensing technology and solutions are designed to handle a variety of simple and complex applications, with components made for increased safety, superior performance, and longer productivity.
