Working Mechanism

  • A differential air pressure switch works by monitoring the difference in air pressure between two points in an industrial or HVAC system. Inside the switch, there is a diaphragm or sensor that responds to pressure changes.
  • When the pressure difference reaches a pre-set level, an electrical switch is activated. This switch can be programmed to perform specific actions, such as turning on fans or alarms.
  • It continually checks the pressure difference and makes adjustments as needed to maintain the desired levels. This mechanism ensures safety and efficiency in various applications by regulating airflow and preventing contamination.

Features

  • Johnson Controls differential air pressure switches feature moulded polycarbonate enclosures for resisting corrosion on exposed surfaces and rigidity to internal components.
  • They have Buna-N diaphragm for preventing leakage.
  • These differential air pressure switches can be operated at temperatures ranging from -40 to 165 degrees F.
  • They offer detachable covers for adjusting the set scale and preventing unauthorised access.
  • These air pressure switches have FNPT x NPSM connectors for secure connections.
