Devices with Diaphragm Seal

Remove the protective cap or protective wrapping from the diaphragm only just before in-
stallation to prevent contamination or damage.
The diaphragm must not be touched. Do not place the device on its diaphragm. Even
small scratches or deformations may negatively influence the zero point or other charac-
teristics of the device.
Pressure transmitter and diaphragm seal are a closed system that must not be separated.
You can find further information about diaphragm seals in the document TA_031 on
