PST and Fiber Optic Sensors

In fiber optic sensors, PST refers to a type of miniaturized optical sensor, such as the FTC-PST3, used for non-invasive oxygen measurement.Definition and FunctionPST in this context stands for PreSens Technology, which is a designation used by PreSens for their optical oxygen sensor spots integrated into flow-through cells (FTC-PST3) for fiber optic systems . These sensors are chemical optical sensors that allow non-invasive, online monitoring of oxygen in liquids or gases. The sensor spots are connected to an oxygen meter via a polymer optical fiber, enabling remote measurement without direct electrical contact.Key FeaturesMiniaturized Design: The PST sensors are small and can be integrated into flow-through cells of various sizes and shapes.Non-Invasive Measurement: Oxygen is measured through the transparent vessel wall, avoiding contamination or interference with the sample.Versatility: PST sensors can be used in stirred or non-stirred applications, and the sensor spots are optically isolated to prevent light interference.Integration: The sensors connect to meters like the Fibox 4, allowing real-time monitoring and data collection.ApplicationsPST fiber optic sensors are commonly used in:Perfusion systems for biological researchPhotosynthesis measurementsRespiration monitoring in laboratory vesselsIndustrial or laboratory processes where non-invasive oxygen measurement is requiredSummaryIn fiber optic sensor terminology, PST identifies a specific type of optical sensor spot designed for precise, non-invasive oxygen monitoring, typically used with PreSens meters and connected via polymer optical fibers. This technology leverages the advantages of fiber optics, such as immunity to electromagnetic interference and the ability to measure in remote or hazardous environments .
