Sensortechnics’ HCLA pressure sensors measure
ultra-low gage or differential pressures from 2.5 mbar (1 inH2O) Full Scale.
The sensors perform precision digital signal conditioning and achieve very high
accuracies. The HCLA series provides a digital I2C bus interface plus an analog
0.5…4.5 V output signal at the same time. This offers OEM customers increased
design flexibility (e.g., in order to build up a redundancy functionality for
safety critical applications). The sensors can directly communicate with
microcontrollers without the need for additional A/D converters. Further,
digital SPI bus and custom specific outputs are available on request.
HCLA pressure sensors use a special
compensation technique to achieve a very high offset stability and virtually no
position sensitivity. Together with an optional 3 V supply (standard 5 V), the
sensors are therefore ideal for battery powered portable or handheld devices. A
wide range of miniature single inline and SMT housing options allows for
flexible and space-saving PCB-mounting. All HCLA pressure sensors can be
modified according to customer specific requirements (e.g., with respect to
pressure range, resolution and internal digital settings).
