What is a differential pressure switch?
A differential pressure switch is a sensing device that measures the pressure difference between two points in an air or gas system. When the pressure reaches a predefined value, the switch changes its electrical contact position to start, stop, or signal connected equipment.
Unlike a standard pressure switch that measures pressure at a single point, this device compares pressure between two separate ports. This makes it ideal for applications where airflow, filter condition, or ventilation performance needs continuous monitoring.
In modern HVAC and industrial systems, pressure monitoring plays a vital role in maintaining efficient airflow and protecting equipment from abnormal operating conditions. By detecting pressure variations early, the switch helps prevent unnecessary downtime while supporting energy-efficient system performance.
How the Beck 930 Works
The Beck 930 continuously compares pressure between its high-pressure and low-pressure ports. Inside the housing, a precision diaphragm responds to changes in pressure. Once the preset switching value is reached, the internal microswitch activates and sends a signal to the connected control system.
This simple operating principle allows the device to monitor airflow accurately while responding quickly to changing operating conditions.
Operating Process
Pressure Detection
The pressure ports measure the pressure on both sides of the system, such as across an air filter or ventilation duct.
Pressure Comparison
The internal sensing mechanism compares both pressure values in real time to determine the pressure difference.
Automatic Switching
When the configured pressure level is reached, the microswitch changes its contact position automatically.
System Response
The output signal can activate alarms, start or stop fans, indicate clogged filters, or communicate with a building management system for automated control.
