Differential pressure sensor is a relatively common measuring instrument in industrial production. Because of its high measurement accuracy, it has been widely used in many industrial production fields. The working principle of the differential pressure sensor: the differential pressure from the pressure pipes on both sides directly acts on the double-sided isolation diaphragm of the pressure sensor, and is transmitted to the measuring element through the sealing liquid in the diaphragm. The measuring element converts the measured differential pressure signal into The corresponding electric signal is transmitted to the converter, and becomes a standard electric signal output after amplifying and other processing.
Differential pressure sensors are commonly used in test benches, wind tunnels, leak detection systems, and other applications. Engineers in every application area are looking for sensor improvements that are important to their industry. For example, engineers who design and use test benches expect measurement instruments to have very high accuracy because accurate air flow measurements are required to calculate system performance. The test bench can use a differential pressure sensor to measure the gas flow into the diesel engine to determine performance, or to measure the efficiency of off-highway vehicle engines.
On the other hand, wind tunnel engineers are very interested in differential pressure sensors with high accuracy and fast response time. Low-speed wind tunnel applications require the measurement of varying air velocity. Therefore, differential pressure sensors can be used to calculate the wind speed of an airplane, measure how air flows through a car, or help determine the best curvature and spacing of wind turbine blades. These applications rely on differential pressure sensors and Pitot tubes to accurately and reliably measure local air velocity.
The high and low pressure ends of the differential pressure sensor are protected by an isolation diaphragm, and both pressure chambers can contact corrosive fluid media. The measured pressure difference is transmitted to the silicon pressure-sensitive element through the isolating diaphragm and the filled silicone oil to achieve accurate pressure difference measurement. For the choice of pressure sensor, use MS5534C silicon piezoresistive pressure sensor-MS5534C, the pressure sensor uses advanced ADC analog-to-digital conversion IC, providing 16-bit pressure and temperature digital output.
MS5534C has stronger anti-static ability (4kV). Used in handheld altitude/atmospheric pressure systems, weather control systems, adventure or multi-function watches, GPS, etc. There is also a differential pressure sensor-SDPx108 series, which has a faster response time, making this series of differential pressure sensors a perfect solution for respiratory equipment and automation applications with strict timing requirements.
