SOP8 packaged pressure sensor head
overview
This product uses a MEMS piezoresistive absolute pressure sensor chip with a silicon silicon bonding structure, which is packaged in a S0P-8 plastic casing through a special process. Under standard working constant voltage and current power supply, the sensor can output millivolt level voltage signals that have a good linear relationship with the measured pressure.
