- Hydraulic systems The P122 piezoresistive pressure sensors are offered in a miniature 0.10 in x 0.10 in (2.5 mm x 2.5 mm) die. When excited with 1.0 mA, the P122 produces a millivolt output that is proportional to input pressure. The P122 is available as an absolute pressure sensor where the media pressure is referenced to an internal vacuum sealed in the die. With NovaSensor’s SenStable process, the P122 will provide very good long-term stability and excellent repeatability. Amphenol Advanced Sensors
