* Max. Differential pressure: 5000Pa
* Protection Class: IP54
* Output: 1.0A (0.4A)/ 250VAC
* Working temperature: -20~85 C
* Storage temperature: -40~85 C
* Min. Actuating pressure: 20Pa(Standard);
Min. Starting interval: 10Pa;
Range: 20~30Pa
* Installation Direction: Vertical (standard installation style)
* Hose connection: Pipe P6.2mm
Possible fields of application include:
* Monitoring air filters and ventilators
* Monitoring industrial cooling-air circuits
* Maximum air flow controller for variable air volume systems
* Overheating protection for fan heaters
* Monitoring flows in ventilation ducts
