Features
SS111 series PCB mount pressure sensor has a diameter of 19mm and a height of 4mm only. A highly stable piezoresistive silicon die is mounted in the stainless steel housing. A transparent silicon gel layer protects it against the influence of the external environment. The pressure acts on the gel layer and transfers it to the chip. The sensor is available for pressure ranges from 6 bar to 25 bar (600 kPa to 2.5 MPa). While not temperature-compensated, it maintains reliable performance.
The electrical connection is made via a five-pin header, allowing a PCB to be soldered directly to the header pins. Typical Applications: Barometric, meteorology, pneumatic control instruments, robotics, sanitary and pharmaceutical gases, air conditioning.
