Digital miniature ultra-low pressure sensors
Sensortechnics’ HCLA pressure sensors measure ultra-low gage or differential pressures from 2.5 mbar 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, eg with respect to pressure range, resolution and internal digital settings.
Features of the HCLA series are:
* Ultra-low pressure ranges from 2.5 mbar Full Scale.
* I²C bus and analog output at the same time.
* Optional 3 V power supply (standard 5 V).
* Miniature single inline and SMT housing options.
Typical applications of the HCLA pressure sensors include medical devices, instrumentation, environmental controls and HVAC.
