Siemens Pressure Switches QPLx5

The pressure switches are designed for monitoring gas or air pressure.

When the pressure drops below or rises above the preset switching point, the corresponding electrical circuit either opens or switches over. They are typically used for supervising air or gas pressures in gas trains of gas-fired equipment, such as gas burners.

The QPLx5… models are suitable for both minimum and maximum pressure monitoring, with an adjustable working pressure range up to 500 mbar. They can withstand continuous operating pressures up to 690 mbar and are suitable for gases from families 1, 2, and 3, as well as other neutral gaseous media.
