MAP36A-LP sensors come with a calibrated voltage output for pressure measurement of .15 to 3 psi. Input of 2.7 to 5.5V. 5 pin plastic button cell, differential or gauge models.
The MB-LPS1-01 Series of low microflow pressure sensors measure differential air (or other non-corrosive gas) pressure, inferring differential pressure from nano-liters per second gas-flow through an integrated airflow channel having high flow impedance. Measurement ranges from 0.1" to 2" of water. 3 models, including 3V supply available. Very high overpressures acceptable!
SLP35A-LP sensors come with a calibrated voltage output for pressure measurement of .3-3 psi. With a footprint of 10 mm by 10.2 mm and a height of 10 mm, these sensors are extremely small! Gauge or differential.
