E+H differential pressure transmitterThe product features are introduced as follows:

① Absolute and gauge pressure measuring instruments with ceramic sensors, monocrystalline silicon piezoresistive sensors, or diaphragm sealing systems are particularly suitable for various applications in the process and hygiene industries.

② Using the correct sensor technology and specialized equipment, Endress+Hauser provides pressure transmitters that allow for quick setup, easy debugging, and save on usage and time costs.

③ Monocrystalline silicon piezoresistive sensor: can be used in situations where the process pressure does not exceed 700 bar (10500 psi), equipped with small-sized flush installation process connections to ensure overload resistance and minimal temperature impact.

④ Diaphragm sealing system: Provides various special materials and process connections, with a process temperature range of -70...+400 ° C (-94...+752 ° F).

⑤ Pressure switch: Function check and display on-site information through LED indicator lights and digital display screens, operated and displayed through personal computers, providing stainless steel casing and laser engraved nameplates.

⑥ Piezoresistive sensor: Under the action of working pressure, the isolation diaphragm undergoes deformation, and the value of the varistor in the bridge changes, thereby realizing the conversion of pressure into voltage signal (monocrystalline silicon semiconductor technology).

⑦ The voltage variation of the bridge is measured and the output is calculated.

⑧ Pressure switch: When the set pressure value is reached, open or close the electrical PNP contact. In addition, it also provides 4... 20 mA output signals.
