English The differential pressure switch QPD15 is used to monitor the air pressure and air flow rate. If the pressure falls below or exceeds the set switching point, the connected circuit is interrupted or switched over.
Application
- For monitoring air pressures or air flows of oil or gas appliances (burners, boilers, ovens)
- QPD15 are suitable for an absolute pressure or a differential pressure
- Adjustable working pressure ranges up to 5 kPa (depending on pressure range)
- Suitable for a permanent operating pressure of up to 50 kPa
- Suitable for air
Technical data QPD15.005
Permissible operating pressure: 50 kPa
Working pressure range: 0.05...0.5 kPa
Switching differential: 0.04 kPa
Factory setting: 0.05 kPa
Medium: Air
Switching voltage AC eff. max. 250 V, DC 24...48 V
Switching current AC eff. max. 6 A bei cos? 1, AC eff. max. 2 A at cos? 0.6, AC eff. min. 20 mA, DC max. 1 A, DC min. 20 mA
Weight approx. 142 g
Installation position: Horizontal or vertical, but not overhead
Protection class IP54
