English The Siemens QPL compact pressure switch is used to monitor the gas pressure or air pressure. 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 gas pressures on gas lines of gas appliances (gas burners)
- QPLx5 are suitable as minimum pressure monitors or maximum pressure monitors
- Adjustable operating pressure range up to 50 kPa (depending on pressure range)
- Suitable for gases of gas families 1 / 2 / 3, hydrogen and other neutral gaseous media
Technical data QPL 25.010B
1/4” connection on the bottom
Working pressure range: 0.2...1.0 kPa
Switching differential: 0.15 kPa
Factory setting: 0.2 kPa
Switching voltage: AC eff. max. 250 V, DC 24...48 V
Switching current: AC eff. max. 6 A at cos? 1, AC eff. max. 2 A at cos? 0.6, AC eff. min. 20 mA, DC max. 1 A, DC min. 20 mA
Protection class: IP54 according to protection class II in accordance with EN 60730-1:2016
Gas family: 1, 2, 3 according to EN 437:2018, <1% H2 (see “Notes” in the manufacturer's declaration); <1% NH3
