EPDS Differential air pressure
Description
EPDS differential pressure switches are designed for monitoring overpressure, negative pressure, and differential pressure in systems handling air and other non-aggressive gases.
These mechanical switches provide a cost-effective solution for pressure monitoring in filters, fans, blowers, ventilation ducts, and heat recovery ventilation systems.The switching setpoint can be manually adjusted.
Characteristics
Enclosure material: ABS plastic;
Construction materials: ABS and PC plastic;
Diaphragm: silicone;
Electrical connections:
- Terminal type: screw terminals;
- Cable cross-section: 0.2 to 1.5 mm² (24 to 16 AWG);
- Tightening torque: 1.5 Nm.
Ambient temperature: -20 to +60 °C;
Relative humidity: 0 to 95% RH (non-condensing);
Protection rating: IP54;
Dimensions: 90 × 105 × 63 mm (W × H × D);

Use
The pressure switch is particularly suitable for control and safety in air conditioning systems, providing indication of:
- fan failure;
- filter clogging;
- lack of airflow across electric heating coils.
It is intended for use in environments with non-aggressive and non-flammable air and gases.
Operating Data
Pa: pressure drop in Pascal.
