1) Details must be tested separately in the respective application. The specified values for the max. nominal
pressure serve only as a rough orientation. The values depend on the temperature, the seals used, the selec-
ted torque, the type and the material of the mating thread and the prevailing operating conditions.
2) Model MH-3-HY is delivered without sealing. Depending on the process connection and measuring range,
including overload safety, an appropriate sealing has to be selected.
The sealings listed under "Standard" are included in the delivery (only for model MH-3).
