NovaSensor P162 Medical Silicon Gage Pressure Sensor Die are piezoresistive pressure sensor die offered in a miniature 1150 x 725 mm die that is small enough for three French catheters. The small die size is made possible by NovaSensor’s proprietary Silicon Fusion Bonding (SFB) process. When excited with an AC or DC voltage source, the P162 produces a mV output that is proportional to input pressure.
The P162 is in a halfbridge design, where external resistors are needed to complete a full bridge configuration.
Features
- Very small size
- Gage pressure sensing
- Standard pressure range –50 to 300 mmHg Gage
- AC or DC excitation
- 4000 mmHg burst limit
- Wafer location marked on every die for traceability
- Tight control of sensitivity
