In the following charts, the typical values for the temperature coefficient "TK Process" are listed
apart from the dimensions. The values apply for silicone oil and the diaphragm material 316L. For
other filling oils, these must be multiplied with the TK corrective factor of the respective filling oil.
The stated nominal pressure applies to the chemical seal. The max. pressure for the complete
measuring system depends on the weakest element (with regard to pressure) of the selected com-
ponents.
In the charts you see the weights of the chemical seals. For the weight of the transmitter see also
"Dimensions and weights" in operating instructions VEGADIF 65.
