Product overview         
The PC12III OEM products adopt a one-time oil filling technology. The diaphragm directly contacts the measuring medium, and the pressure is transmitted to the pressure chip through silicon oil to generate an electrical signal. The compensation circuit will modify the pressure signal to a linear pressure signal.  
Thread end face stress diaphragm exposed directly feel the pressure, using open corrugated structure, resistant to touch, external pressure through stainless steel diaphragm, internal seal of the medium oil transmitted to the sensitive chip. The sensitive chip does not directly contact the measured medium, forming an all-solid structure for pressure measurement, so the product can be used in various occasions, including harsh corrosive medium environment.
