Direct Mounted Diaphragm Seal Differential Pressure Transmitter - China

Direct Mounted Diaphragm Seal differential pressure transmitter Description: The capacitive differential pressure transmitter can measuring liquids’ level and density of kinds of container accurately.

Transmitter is mounted to the container with pipe flange.

Be propitious to measuring medium of high temperature, high viscosity and easy to subside or strong corrosive.

Diaphragm subassembly have plane and plug-in types.

flange size: 3inch and 4inch; pressure grade: 50Ib and 300Ib.

The membrane can select 316 stainless steel, Hastelloy or tantalum according to measure medium.
