Due to the increasing demand for precise pressure sensors suitable for manifold assembly Analog Microelectronics has expanded its digital I2C pressure sensor series AMS 5915 by corresponding variants. These PCB-mountable pressure sensors come in a robust ceramic DIP-08 package with a very low assembly height of approximately four millimetres and are designed for manifold assembly on flanges with o-ring seals.
The AMS 5915 for manifold assembly are available in pressure ranges from 5 mbar up to 16 bar for relative and differential pressure measurements.
Special variants of the AMS 5915 sensors for pneumatic applications are available in pressure ranges from four 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 3.3V. They are digitally calibrated, linearised and extensively temperature compensated in a wide operating temperature range of -25 to +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 0.5ms 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.
