Customised, high precision, digital low pressure sensors from Fujikura
PEWATRON:.Fujikura officially released the new digital AL4 series of gauge low pressure sensors for volume production. The AL series has a very small footprint (11.36 mm x 10.32 mm) in comparison with other low sensors, SMT pin configuration and a high total accuracy (+/-1.5% FSO) within a compensated temperature range of 0°C to 50°C.
The digital AL4 series is a two-chip system consisting of a piezo-resistive pressure sensing chip with a very high maximum load pressure of 100 kPa and an ASIC signal conditioning chip. The ASIC allows digital signal conditioning and communication via the I2C protocol. The digital AL4 series low pressure sensor product follows the successful introduction of the analogue, high precision A2 series pressure sensor and the digital, high precision A4 series pressure sensor.
The heart of the ASIC is a 14-bit ADC, which achieves the equivalent sensitivity of up to 0.15 Pa/LSB for 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 sensors are delivered in the usual high quality Fujikura packages comprising tray, tape and reel, according to customer specification.
Standard measurement ranges are between 0 kPa to 2 kPa and 0 kPa to 10 kPa; non-standard ranges are available on request. The pressure range is configurable as positive, negative or bidirectional gauge. Supply voltage is configurable at 3.0, 3.3 or 5.0 VDC.
