The accuracy level of a pressure sensor is usually classified according to its margin of error. The different accuracy levels represent the amount of error in the measurement process of the sensor. Common accuracy classes include C3, C2, C1, G1, G2, G3 and G5. Entre eles, C3 has the highest accuracy, with an error range within ±0.020%, Ou seja,, 2 parts per million accuracy; while G5 has the lowest accuracy, with an error range within ±0.5%, Ou seja,, 5 parts per thousand accuracy.
Para testar um sensor de pressão, é necessário olhar para sua aparência, resposta de pressão, ponto zero, circuito e desempenho elétrico. Analisando e julgando de forma abrangente os resultados do teste, 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, cenários de aplicação, environmental factors, e custo.
Gauge pressure sensor is a sensor that measures the relative pressure, isto é. o valor da pressão em relação à pressão atmosférica. 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.
Submersible pump pressure sensors operate on the principle of electrical signal changes due to pressure changes. Typically, the pressure sensor contains a pressure sensitive 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.
Sensores de pressão, 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.

Sensores de pressão diferencial, 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.
