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.

Lufttryckssensor är en kärnkomponent i en väderprognosmaskin som stöder realtid väderprognos genom att mäta atmosfäriska tryckförändringar med hög noggrannhet. This paper analyzes the working principle, functional implementation and selection criteria of air pressure sensors, and explores their applications and future development trends in households, portable devices and weather stations, including the directions of intelligence, low power consumption and miniaturization, in order to provide technical guidance for the optimization of weather monitoring devices.

The inflatable pump sensor can help to solve the problem of unstable inflatable equipment by real-time monitoring of air pressure, pressure, temperature, flow and other parameters during the inflatable process with high accuracy and efficiency.

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.
