Badotherm has full welded constructions available for all leading transmitter brands. Next to the selection of a full welded construction with the presence of vacuum, we also recommend you to verify the suitability of the filling fluid for vacuum conditions (see the vapor pressure curve). It is also important to not forget to mount the instrument below the (lowest) diaphragm seal in order to protect the instrument at all possible conditions (50 cm).
