Osisense XM - Is the XMLG pressure transmitter compatible with the refrigerant R404A?

1) The XMLG pressure transmitter uses an internal gasket with the ceramic cell, in fluorocarbon FPM (Viton). Such material is not compatible with the refrigerants basically, including the R404A.

2) For HVAC or refrigeration application using some refrigerant like the R404A, you have to select an XMLP sensor with the fluid entry 7/16-20UNF, with no external Viton gasket on the fluid connection. Example XMLP016BD27.
