Pressure sensors are widely used in various industrial applications to measure and monitor pressure levels. The XIDIBEI pressure sensor is a high-quality sensor that offers accurate and reliable pressure measurements in harsh industrial environments. However, there are different types of pressure sensors, including differential pressure sensors and pressure sensors. In this article, we will discuss the differences between these two types of sensors.
Differential Pressure Sensor
A differential pressure sensor is a type of sensor that measures the difference between two pressures and is typically used to measure the pressure difference between the front and back of a device or component. The housing of the differential pressure sensor is made of aluminum alloy or stainless steel, and it has two pressure ports with M10 threads and a Ф6 tower structure. Differential pressure sensors are widely used in various industrial applications, such as textile workshops, boiler air supply, underground ventilation, power, coal, spinning cotton boxes, dust removal equipment, and industrial pressure process control.
The working principle of the differential pressure sensor is that the measured pressure directly acts on the sensor's diaphragm, causing the diaphragm to produce a proportional displacement to the water pressure. The capacitance value of the sensor changes, and the change is detected through the electronic circuit and converted into a standard measurement signal corresponding to the pressure output.
A pressure sensor is a type of sensor that measures the pressure at a single point. The pressure sensor uses the piezoresistive working principle, where changes in pressure cause a change in the resistance of the sensor. This change in resistance is then converted into a measurable signal, which can be either an analog or digital output.
The main difference between differential pressure sensors and pressure sensors is in the measurement parameter. Differential pressure sensors measure the relative pressure difference between two points, while pressure sensors measure absolute pressure.
Another difference is in the interface. Differential pressure sensors have two input nozzles to connect to two measuring points, while pressure sensors have only one connection nozzle.
The pressure difference is the difference between the two measured pressures acting on the sensor's two sides. Any measurement requires comparing the pressure flow detected on the two pressure guiding ports of the sensor.
In conclusion, differential pressure sensors and pressure sensors are both used to output the size of the pressure difference between two ends of a measured object. However, they differ in the measurement parameter, interface, and pressure difference. The XIDIBEI pressure sensor is a high-quality sensor that offers accurate and reliable pressure measurements in various industrial applications, whether it is a differential pressure sensor or a pressure sensor. The choice of the type of sensor depends on the specific application requirements and measurement needs.
