AMS 5915 Board Mount Pressure Sensor with Digital I2C Output
Pressure Medium: AIR/GAS
Sensor Type: DIFFERENTIAL, ABSOLUTE, BAROMETRIC
Supply Voltage: UNDER 5V
Output Signal: DIGITAL
Pressure Range: UNDER 4” H2O, 3-300 PSI
The pressure sensors in the AMS 5915 series are high-precision board mount sensors with a digital I²C-interface. They combine a micromachined, high quality piezoresistive pressure sensing element with a modern, mixed-signal CMOS-ASIC used for signal conditioning on a ceramic substrate. AMS 5915 sensors are extensively calibrated and compensated across a wide temperature range of -25 to 85 °C.
The AMS 5915 come in a compact and robust ceramic dual in-line package (DIP) for assembly on printed circuit boards (PCBs). Two package variants are available: one with vertical pressure ports for hose connection and one for O-ring sealing (Npackage type for manifold mount). The sensors are operational without any additional components.
The electrical connection is established via DIP solder pins and pressure is connected either by using flexible tubing on the metal tubes or a suitable
flange.
The sensors in the AMS 5915 series are available in various pressure ranges for all pressure types:differential (relative) pressure sensors in ranges from 0 ... 5 mbar up to 0 ... 16 bar, absolute pressure types from 0 ... 500 mbar up to 0 … 2 bar and 700 ... 1200 mbar for barometric measurements. Bidirectional differential sensors are available in pressure ranges from -2.5 ... +2.5 mbar up to -1 ... +1 bar.
Custom specific pressure ranges or modifications are available on request.
