With the continuous development of technology, the performance of sensors is also continuously improved, and the sampling rate, sensitivity, 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. Ketika sensor tekanan pengukur mengukur kurang dari tekanan atmosfer, ia menghasilkan pembacaan tekanan negatif. 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.
Sensor tekanan pada ventilator adalah komponen IC utama yang digunakan untuk mengukur dan memantau perubahan tekanan gas. Ini memainkan peran penting dalam sistem ventilator, memastikan bahwa perangkat tersebut mampu mengontrol aliran gas, tekanan, dan rasio pencampuran secara akurat sesuai dengan kebutuhan pernapasan pasien.
Sinyal keluaran sensor analog adalah nilai tegangan atau arus kontinu, berbanding lurus dengan perubahan tekanan, sensor digital dalam sinyal keluaran lebih menguntungkan, modul konversi analog-ke-digital bawaan dan unit pemrosesan sinyal, data sensor langsung diubah menjadi sinyal digital seperti I2C atau SPI untuk transmisi.

Sensor pompa tiup dapat membantu memecahkan masalah peralatan tiup yang tidak stabil dengan memantau tekanan udara, tekanan, suhu, aliran, dan parameter lainnya secara real-time selama proses tiup dengan akurasi dan efisiensi tinggi.
Everyone should know that smartphones, watches and mobile devices have built-in barometric pressure sensors, but we are still unfamiliar with air pressure sensors. Literally, a pressure sensor is used to measure air pressure, but what is the purpose of measuring air pressure for the average cell phone user?
The innovative role of gas pressure sensors in gas sensing technology is mainly reflected in its detection accuracy, response speed, stability and durability of the enhancement of the gas concentration, gas flow and gas state monitoring becomes more efficient and accurate, improving the accuracy of gas detection.
TPMS sensors are classified as direct, indirect, or hybrid, with direct providing accurate readings but at a higher cost, and indirect at a lower cost but not measuring air pressure directly.TPMS improves safety, extends tire life, improves fuel efficiency, and prevents degradation of handling and braking due to low tire pressure.
Water pressure sensors need to comprehensively consider resolution, waterproof level and other performance indicators. For sensors that are used for long-term diving, a higher waterproof level is required. For applications involving a wide pressure range, a wider resolution range is usually required to ensure accurate measurement results under different working conditions.
5V and 3.3V represent the input voltages required for sensor operation. 5V sensors are widely used in industrial equipment due to early technology limitations. 3.3V is becoming more popular as semiconductor processes advance, especially in portable and low-power devices.
Digital pressure gauge uses gas pressure sensor, which can convert the pressure of gas or liquid into digital signal and display the pressure value intuitively through digital display.
Min air pressure sensors, because of their high accuracy and small size, are essential to ensure the reliability and measurement accuracy of the sensors. The basic principles of calibration include comparison, range, temperature and long-term stability calibration. The calibration procedure covers preparation, data collection, data processing and record reporting.
