Stainless Steel Media Isolated Industrial Pressure Sensor and Transmitter

The AV400 Pressure Sensor is design for industrial and offroad applications. It employs p-n junction free MEMS piezo resistive technology that is inorganically bonded for media isolation. Because of one-piece stainless steel structure, AV400 provides reliable operation in harsh environment. It is well suited for OEM machinery, process control, automation, plastic and alloy injection molding machines, hydraulic, etc.
