<p>Pressure sensors, also known as pressure indicators, are instruments that are used to measure the pressure of gases and liquids. They can also be used indirectly to measure the flow of fluids and gases, speed, water level and altitude, as well as other variables. These instruments are generally used in oxygen concentrators, pneumatic controls, ventilators, indoor air quality systems, among others.</p><p>SSCDANN030PAAA5 Pressure Sensor from Honeywell offers a ratiometric analog or digital output. Featuring an internal vacuum reference, this Honeywell Sensor delivers an output value that is proportional to absolute pressure. With a wide variety of pressure ranges, this Absolute Sensor is ideal for use with non-corrosive, non-ionic liquids.</p>
