The AQS-2 Quick-Select pressure module incorporates a piezoresistive, micromachined silicon sensor. These sensors are available in ranges from 0/100 inches H2O through 0/10,000 psi and are also offered in absolute, vacuum and compound variants.
AQS-2 sensors are available for gauge and absolute pressure or vacuum measurement. 316 SS sensor isolation is provided on most ranges for applications involving fluids or corrosive gases. AQS-2 Quick-Select pressure modules are available in a variety of accuracies from ±0.1% of span through ±0.025% of span.
