Differential pressure sensors are widely used across various industries for measuring the pressure difference between two points. These sensors are critical in applications such as flow measurement, filter monitoring, level detection, and process control. Below is a aaplication guide for differential pressure sensor：

1. Flow Measurement
Differential pressure sensors are commonly used for measuring fluid flow, especially in pipelines or equipment. By detecting the pressure difference before and after the fluid flow, the flow rate can be calculated. They are widely used in industries such as oil, natural gas, chemicals, paper manufacturing, and water treatment. Since the flow velocity of the fluid is proportional to the pressure difference in the pipeline, differential pressure measurement sensor can precisely control and monitor the flow rate, ensuring a stable supply of raw materials and process safety.

2. Filter Monitoring
Differential pressure sensors are used to monitor the working condition of filters, especially in HVAC systems (heating, ventilation, and air conditioning) and industrial air purification systems. When the pressure difference across the filter exceeds a set threshold, it indicates that the filter may be clogged and needs cleaning or replacement. By continuously monitoring the pressure difference, the efficiency of equipment maintenance can be improved, and performance degradation or failure caused by clogged filters can be avoided.

3. Liquid Level Measurement
Differential pressure sensors are widely used in liquid level measurement, particularly in tanks, containers, or liquid storage vessels. By measuring the pressure difference between the upper and lower surfaces of the liquid, the liquid level can be determined. This method is common in industries like oil and gas, food and beverage, and pharmaceuticals due to its non-contact, high-precision advantages. It is capable of working stably in harsh environments with high temperature and pressure.

4. HVAC and Airflow Control
In HVAC systems, differential pressure sensors are used to monitor airflow and system operation. By detecting pressure differences as air passes through ducts, filters, and fans, airflow can be precisely adjusted, and system efficiency can be ensured. Differential pressure transducers not only help detect filter clogging but also regulate the load on the air conditioning system, ensuring a comfortable air environment while improving energy efficiency.

5. Safety Monitoring and Process Control
In critical industrial equipment, differential pressure sensors play an important role in safety monitoring. For example, in reactors, pressure relief valves, steam boilers, and other equipment, differential pressure sensors are used to monitor the pressure difference between the inside and outside of the equipment, ensuring stability and safety. Any abnormal pressure difference may indicate a fault or excessive pressure, which could lead to an accident. By continuously monitoring and issuing early warnings, differential pressure sensors help detect potential issues in time, reduce equipment failures, and mitigate safety risks, making them widely used in high-risk industries such as chemicals, power generation, and pharmaceuticals.

Differential pressure sensors are versatile and essential tools for numerous industrial applications. Whether used for flow measurement, filter monitoring, or process control, these sensors help ensure system efficiency, safety, and reliability. When selecting a sensor, it is crucial to consider factors such as the application type, environmental conditions, and sensor specifications to ensure optimal performance.
