    Understanding Pressure Sensors

    A pressure sensor, also known as a pressure transducer or pressure transmitter, generates an electrical output from the force that is generated by gases or liquids. This output is available for display, processing or activation and control of machinery and safety systems.

    Pressure is generally measured in pascals (Pa), bars, atmospheres (atm) or pounds per square inch (psi). Based on the system requirements, sensors can measure the following:

    • Absolute pressure: Pressures with respect to a perfect vacuum. Great for weather stations or altitude measurement.
    • Gauge pressure: Pressure relative to atmospheric pressure. For use in hydraulic systems, automotive applications and other fluid transfer system pipelines.
    • Differential pressure: Measures the difference between two points. Used in testing and monitoring HVAC systems, filtration efficiency and cleanroom services.

    Precise pressure measurements are essential for preserving system integrity, maximising performance and safeguarding in both industry and research settings.

    A pressure sensor is a device used to measure and monitor the pressure of fluids or gases. It detects changes in pressure and converts them into an electrical signal that various systems can interpret and utilise. Pressure sensors are also widely used in industries across Australia, such as automotive, manufacturing, aerospace, and healthcare, to ensure proper functioning and safety.

    There are various types of pressure sensors available, including: 

    • Strain gauge pressure sensors: Utilise the deformation of a strain gauge to measure pressure. 
    • Capacitive pressure sensors: Measure pressure changes by detecting the variation in capacitance. 
    • Piezoresistive pressure sensors: Utilise the change in resistance of a material under pressure to measure pressure. 
    • Digital pressure sensors: Provide a digital output, often in the form of a digital communication protocol. 

    Pressure sensors work based on different principles. For example, a strain gauge pressure sensor contains a thin metal diaphragm that deforms under applied pressure, causing a change in resistance. This change is then measured and converted into an electrical signal. Similarly, capacitive low cost pressure sensors measure changes in capacitance caused by pressure-induced deflection. Piezoresistive pressure sensors use the piezoresistive effect, where the resistance of certain materials changes when subjected to pressure. 

    Oil pressure is crucial for the proper functioning and lubrication of an engine. An oil pressure sensor monitors the oil pressure. It alerts the driver or engine control system if the pressure falls below the recommended level. Maintaining proper oil pressure ensures sufficient lubrication of engine components, reduces friction and wear, and prevents engine damage due to insufficient lubrication. It also helps in cooling critical engine parts, such as bearings and pistons. It ensures optimal performance and longevity of the engine.

    Pressure sensors have various applications in Australia, including: 

    • Automotive industry: Monitoring tire pressure, engine oil pressure, and fuel pressure. 
    • Industrial manufacturing: Monitoring and controlling process pressure in machinery and pipelines. 
    • HVAC systems: Monitoring air and gas pressure in heating, ventilation, and air conditioning systems. 
    • Medical devices: Monitoring blood pressure, respiratory pressure, and infusion pressure. 
    • Aerospace industry: Monitoring cabin, fuel, and hydraulic system pressure.

    A faulty oil pressure sensor can potentially cause engine damage if it fails to detect low oil pressure accurately. Insufficient oil pressure can lead to inadequate lubrication, increasing friction, heat, and wear on engine components. Over time, this can cause damage to bearings, camshafts, crankshafts, and other vital engine parts. It is essential to promptly address any oil pressure sensor issues promptly to prevent potential engine damage. Regular maintenance and monitoring of oil pressure, along with the proper functioning of the oil pressure sensor, are crucial for the longevity and performance of the engine.
