Description
The NovaSensor P112 piezoresistive pressure sensor is offered in a miniature 2.7mm x 3.2 mm (0.10 in x 0.12 in) die. When excited with 1.0 mA, the P112 produces a millivolt output that is proportional to input pressure. The P112 is available as an absolute pressure sensor where the media pressure is referenced to an internal vacuum sealed in the die. The P112 is also available as a differential and gauge sensor. With NovaSensor’s SenStable ® process, the P112 will provide very good long-term stability and excellent repeatability. With NovaSensor’s “flat process,” the P112 can be temperature compensated for either a constant current or a constant voltage power supply.
