A differential pressure switch measures the pressure difference between two points and triggers an electrical contact when the set differential is reached. It contains two pressure ports connected to a sensing element, such as a diaphragm or bellows, that moves proportionally to the pressure difference. This dual-port design distinguishes it from the single-port structure common to most compact pressure switch models, as it is engineered specifically to detect pressure differentials rather than absolute or gauge pressure. When this movement reaches the calibrated setpoint, it actuates a microswitch to open or close a circuit. This function is vital for filter monitoring, flow detection, and system protection in industrial and HVAC systems.
Our differential pressure switch (also known as a diff pressure switch) is the ideal choice for water pump systems, delivering reliable protection against dry-running, pipe blockages, and pressure fluctuations. As a specialized liquid differential pressure switch engineered for water-based applications, it serves as the optimal differential pressure switch for water pum, while also excelling as a differential pressure switch chilled water system solution. By monitoring the pressure difference across your pump, it triggers precise control signals to prevent costly equipment damage and downtime, while ensuring stable system operation. Engineered for durability in liquid environments, it offers easy installation, long-term stability, and compatibility with a wide range of pump setups.
