Product Description
SIEMENS BURNERS -
QPL25.150B COMPACT PRESSURE SWITCH
, 0.5-15 KPA RANGE, 1/ 4 INCH CONNECTION, WITH AUTOMATIC RESET
The pressure switches are used for monitoring gas or air pressures.
When the pressure falls below or exceeds the adjusted switching point, the re
spective electrical circuit will be opened or changes over.
The QPLx5... and this Data Sheet are intended for use by OEMs which integrate
the pressure switches in their products.

USE:
Mounting notes
Ensure that the relevant national safety regulations are complied with
By check piping connections ensure that there are no leaks
To prevent the pressure connection from being blocked on the plant, a suitable
preventive precaution must be used
Example: Installation of a fine mesh or filter
The pressure switch can be mounted either horizontally or vertically, but not in a
suspended position (scale must not pointing downward)
The pressure switch can be connected via a ¼“ thread or O-ring, depending on the
type of switch
The test point on QPL... can be opened with a 2,5 mm allen key
Refer also to following Mounting Instructions: 74 319 0551 0 (M7221)
