What is a Differential pressure sensor?

A differential pressure sensor is a device used to measure the difference in pressure between two points. It is commonly used to monitor the flow and pressure of liquids and gases, providing accurate measurements of pressure differences that help in system monitoring and control. Differential pressure sensors are widely used in industrial equipment, environmental monitoring, and HVAC systems, where they accurately detect fluctuations in pressure. These sensors can issue alarms if the pressure difference exceeds a certain threshold, allowing early detection of system anomalies. They are also used to monitor the condition of filters and fluid levels.

Application of Differential pressure sensor

✅ Monitoring HVAC Systems
In HVAC (heating, ventilation, air conditioning) systems, differential pressure sensors are used to monitor air flow and the condition of filters. When filters become clogged, the pressure difference changes, allowing for early detection and maintenance or replacement of the filters.
✅ Monitoring Fluid Levels
Differential pressure sensors are also used to monitor fluid levels in tanks. By installing sensors at the top and bottom of a tank, the pressure difference can be measured, providing an accurate indication of the remaining fluid level.
✅ Monitoring Industrial Process Flow
In industrial machinery, differential pressure sensors are used to measure the pressure difference of liquids and gases flowing through pipelines. These sensors are essential for monitoring whether the flow is normal and detecting any anomalies in the process.
✅ Monitoring Filter Conditions
Differential pressure sensors are widely used in filter systems. When a filter becomes clogged, the pressure difference before and after the filter changes, triggering an alarm and prompting maintenance or replacement of the filter.
