P112

P112: Medium Pressure Sensors

The P112 is a general purpose silicon piezoresistive pressure sensing element that utilizes our patented SenStable® process for superior device stability. The P112 also utilizes a bonded-glass pedestal that provides both thermal and die-attach stress isolation.

Specifications

The NovaSensor P112 piezoresistive pressure sensor is off ered 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 diff erential and gauge sensor.With NovaSensor’s SenStable® process, the P112 will provide very good long-term stability and excellent repeatability. With NovaSensor’s “fl at process,” the P112 can be temperature compensated for either a constant current or a constant voltage power supply.
