Compare 401.93000 with the removed Sensor label. Do not select another Huba 401 just for the housing: the variant code and the electrical values must match.

Sensor Electronic Pressure Differential
This component converts the pressure difference between its two ports into an electrical signal for the equipment's electronics. Although the catalogue calls it a pressure switch, it operates as an analogue transmitter from the Huba 401 family.
The maximum Pressure of 25 mbar is not the measuring range: the photon unit indicates 0 a 3 mbar. It should not be confused with a mechanical open or closed contact Switch.

Catalogued application and selection
Both catalogs associate this Part with Roca Laura 20/20 F. Check the variant of the Boiler, the code 401.93000 and its electrical values. It should not be replaced by another Huba 401 with different code or output signal.
No models are documented for that search.
Compare the Part label installed and the cutting of your variant before you buy.
Before replacing the part
Pneumatic and electrical connections

Questions about this spare part
Is it a Pressure switch contact?
The photographed Huba 401.93000 unit is electronic and provides an analog signal. It does not amount to a mechanical Pressure switch even if it is sold within that category.
Are 25 mbars your range of measurement?
No. The marked range is 0 a 3 mbar; 25 mbar is the maximum Pressure indicated on the label.
