ASP1400: Digital Differential Pressure Sensor with RS232 interface

The Sensirion ASP1400 differential pressure sensor sets standards for offset free, highly accurate measurement of small differential pressures. The sensor measures the mass flow generated by a differential pressure. Supposed that the gas is known and leakage is allowed, smallest pressure differences can be reliably detected.

Features

• Dynamic differential pressure sensor (medium flows through sensor)
• Offset free
• Bidirectional: -100 to +100 Pa
• Zero drift < 0.05 Pa/year @ 2 Pa differential pressure
• Accuracy 0.05 % full scale or 1.5 % measured value
• Lowest detectable differential pressure: 0.002 Pa
• Unique dynamic range from 0.002 Pa to 100 Pa
• Turn down ratio 1:20'000
• Pressure resistance: up to 2 bar overpressure
• Fully calibrated and temperature corrected
• Linearized digital sensor output (RS-232 & SPI)
• Rugged chemically innert PBT housing
• CE-certified / FCC (CFR 47)
• Ideally suited for ultra low differential pressures
• Zero drift & offset free
• Leading CMOSens® Technology for superior performance
• Unbeatable price performance ratio
• Easy-to-use due to calibration & standard digital interface
