For the version "XSJ - Prepared for diaphragm seal mount" in feature 110 "Process connec-
tion" in the order code up to and including 40 bar (600 psi) sensors, Hauser rec-
ommends welding on the diaphragm seal as follows: the total welding depth of the fillet
weld is 1 mm (0.04 in) with an outer diameter of 16 mm (0.63 in). Welding is performed
according to the WIG method.

Information on filling
The diaphragm seal must be filled as soon as it has been welded on.
• After welded into the process connection, the sensor assembly must be properly filled
with a filling oil and sealed gas-tight with a sealing ball and lock screw.
Once the diaphragm seal has been filled, at the zero point the device display should not
exceed 10% of the full scale value of the cell measuring range. The internal pressure of
the diaphragm seal must be corrected accordingly.
• Adjustment / calibration:
• The device is operational once it has been fully assembled.
• Perform a reset. The device must then be calibrated to the process measuring range as
described in the Operating Instructions.
