RF module environment refers to the various external conditions and factors that affect the performance and reliability of these modules.

Graphene sensors have the characteristics of small size, large surface area, Hoge gevoeligheid, fast response time, easy fixation of proteins and maintaining their activity, fast electron transfer speed, and can effectively reduce the impact of surface contamination, making graphene sensors show excellent performance in the fields of electrochemical sensing, photoelectric sensing, gas sensing and flexible sensing.

Pressure sensors play an important role as key components in monitoring and controlling pressure changes in modern industrial, automotive, medical and consumer electronics applications. Echter, due to the complexity and variability of the operating environment, pressure sensors may encounter various failures during use, which may affect their performance and reliability.

Tire Pressure Monitoring System (TPMS) is an electronic system for real-time monitoring of tire pressure and temperature in vehicles to improve driving safety and fuel economy. Tire pressure gauge sensors are the core components of the TPMS system and are directly responsible for capturing the physical condition data of the tires and transmitting it wirelessly to the vehicle control system. The TPMS system processes the data provided by the sensor and sends timely alarms or alerts to the driver to avoid safety accidents caused by abnormal tire pressure.

Pressure sensors are the most important technical component of blood pressure watches. Their application not only realizes convenient blood pressure measurement, but also provides intelligent solutions for health management. With high precision sensors and advanced algorithms, blood pressure watches can provide accurate real-time data and health trend analysis to help users better manage their personal health.

Het nauwkeurigheidsniveau van een druksensor wordt meestal geclassificeerd volgens de foutmarge. The different accuracy levels represent the amount of error in the measurement process of the sensor. Gemeenschappelijke nauwkeurigheidsklassen omvatten C3, C2, C1, G1, G2, G3 en G5. Onder hen, C3 heeft de hoogste nauwkeurigheid, met een foutbereik binnen ± 0,020%, d.w.z., 2 Onderdelen per miljoen nauwkeurigheid; terwijl G5 de laagste nauwkeurigheid heeft, met een foutbereik binnen ± 0,5%, d.w.z., 5 Onderdelen per duizend nauwkeurigheid.

To test a pressure sensor, it is necessary to look at its appearance, druk reactie, nul punt, circuitry and electrical performance. Door de testresultaten uitgebreid te analyseren en te beoordelen, the performance and condition of the sensor can be accurately assessed and provide strong support for subsequent maintenance and use.

Different types of air pressure sensors have significant differences in accuracy. Gauge pressure sensors are suitable for general applications, absolute pressure sensors provide high accuracy, and differential pressure sensors are used for flow and filtration monitoring. Choosing the right sensor requires considering accuracy requirements, Toepassingsscenario's, omgevingsfactoren, and cost.

Gauge pressure sensor is a sensor that measures the relative pressure, d.w.z. de drukwaarde ten opzichte van atmosferische druk. A differential pressure sensor is a sensor that measures the pressure difference between two measurement chambers. An absolute pressure transducer is a transducer that measures pressure relative to vacuum or absolute zero.

Directieve pompdruksensoren werken volgens het principe van elektrische signaalveranderingen als gevolg van drukveranderingen. Typisch, De druksensor bevat een drukgevoelig element, when the external water pressure acts on the element, it will cause its deformation, which in turn changes the internal resistance or capacitance. This change is converted into an electrical signal, which is processed by a circuit that outputs a signal proportional to the water pressure. The submersible pump reads this signal to adjust its operating status, such as starting, stopping, or regulating the pump speed to adapt to different water depth conditions.
