Special variants of the AMS 5915 sensors for pneumatic applications are available in pressure ranges from 4 bar to 16 bar with a particularly high over pressure of 30 bar. Due to their construction one of the sensor’s pressure ports is compatible with liquids; thanks to the pressure being applied on the sensor’s backside it is possible to measure relative pressure not only in gaseous media but also in non-corrosive liquids.
The highly accurate digital pressure sensors from the AMS 5915 series feature a resolution of 14 bit and are ideal for microcontroller applications due to their I2C output and their supply voltage of 3.3 V. They are digitally calibrated, linearized and extensively temperature compensated in a wide operating temperature range of -25 … 85 °C, leading to a low total error of TEB < 0.5 %FSO across the complete operating temperature range. Furthermore the combination of a high quality MEMS element and a modern mixed-signal IC on a ceramic substrate guarantees excellent long term stability. With a typical reaction time of 0.5 ms AMS 5915 is also well-suited for high speed measurements.
For basic evaluation of AMS 5915 Analog Microelectronics offers a USB starter kit, which can also be used to program AMS 5915 to an individual I2C address. To use an AMS 5915 together with an Arduino an example source code for Arduino’s IDE and adapter PCBs for Arduino Uno and Nano are available.
