AL4: Customized, high-precision digital low-pressure sensors from Fujikura
2015-08-10 03:57:31, Angst+Pfister Sensors and Power AG The AL series features a very small footprint (11.36 mm x 10.32 mm), SMT pin configuration and high overall accuracy (+/-1.5% FSO) within a compensated temperature range of 0°C to 50°C compared to other low pressure sensors.
The digital AL4 series is a dual-chip system consisting of a piezoresistive sensor chip with a very high maximum load pressure of 100 kPA and a signal-processing ASIC chip that provides digital signal processing and communication via the I2C protocol. The AL4 Series digital gravure sensors follow the successful introduction of the A2 Series analog high-precision pressure sensors and the A4 Series digital high-precision pressure sensors.
At the heart of the ASIC chip is a 14-bit AD converter that has the equivalent sensitivity of up to 0.15 Pa/LSB of a 2-kPa full-scale sensor. Six slave address codes can be assigned to the pressure sensor for individual communication with the microcontroller master. The pressure sensors are supplied in Fujikura's usual high-quality packaging, with tray or tape and reel, depending on customer requirements.
The standard measuring range is between 0 and 2 kPA and 0 and 10 kPA, other measuring ranges are possible on request. The pressure measurement range can be configured for positive, negative or bidirectional readings and for a supply voltage of 3.0 volts, 3.3 volts or 5.0 volts DC.
