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, en kosten.
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.
Druksensoren, as an important component in pump controllers, are responsible for real-time monitoring of pressure changes in the pump system and providing accurate feedback signals to the control system. The application of pressure sensors has been transformed from traditional mechanical monitoring to digitalization and intelligence. It not only plays an important role in real-time monitoring of pumps, energy efficiency optimization, fault warning and so on.

Sensors are an important part of modern technology. They provide data support for various smart devices by sensing changes in the physical world and converting them into digital signals. With the continuous development of technology, the performance of sensors is also continuously improved, and the sampling rate, gevoeligheid, resolution and accuracy as the important indexes to measure the performance of sensors are of great significance for the selection and application of sensors.
Differential pressure sensors, as an instrument capable of accurately measuring pressure differences, provide real-time, reliable data by accurately measuring pressure differences within the equipment, thus helping the production line to adjust and optimize operational parameters and ensuring that the pharmaceutical production process meets strict quality control standards.
Gauge pressure transducer, also known as a relative pressure transducer, is a device used to measure the pressure at a specific point relative to atmospheric pressure. When a gauge pressure sensor measures less than atmospheric pressure, it produces a negative pressure reading. This characteristic is uniquely valuable in many applications, such as detecting sealing conditions in vacuum packaging machines, monitoring the operating efficiency of industrial vacuum systems, and even regulating pressure in research laboratories.
The pressure sensor in a ventilator is a key IC component used to measure and monitor changes in gas pressure. It plays a vital role in the ventilator system, ensuring that the device is able to accurately control gas flow, pressure and mixing ratios according to the patient’s respiratory needs.
Analog sensor output signal is a continuous voltage or current value, directly proportional to the pressure change, digital sensors in the output signal is more advantageous, its built-in analog-to-digital conversion module and signal processing unit, the sensor data is directly converted to digital signals such as I2C or SPI for transmission.
