Diaphragm pressure gauge structure principle:
Isolated diaphragm in the measured medium pressure deformation, sealing fluid pressure, the formation of a pressure equivalent to P, conduction to the pressure gauge, and then instrumentation shows the measured medium pressure value.
Diaphragm pressure gauge for the combination of products, there are three parts:

Above for the functional header, you can use different functions of the table header, to indicate the purpose of control or.
The middle of the connector to adapt to different media operating temperature and installation location requirements.
Isolator for the following parts, isolators have a variety of interface forms to meet the needs of different process connections; the same time there are a variety of isolation diaphragm material to meet the different corrosive media pressure measurement.
Isolator interface type and size:
Clamp Hygienic interface: MK
Diaphragm and the card sets of materials: 316
Seal material: silicone rubber
Connector type and size:
Use and Ordering Information:
Instrument operating environment should be no corrosive gases.
Please do not disassemble or replace the instrument has been configured in order to avoid leakage of filling liquid affect the performance. Order Please specify the configuration of the instrument name, model, measurement cap, accuracy and connection pipe type, hose length, isolator interface type, isolator interface materials, Diaphragm material, and flange pipe diameter, standard code, etc. If you require the configuration of other types of instruments, please specify in detail.
The company can also be customized according to user requirements of imported equipment, diaphragm pressure gauge.
