Measuring ultra-low gage or differential pressures from 2.5 mbar full scale, Sensortechnics’ HCLA pressure sensors perform precision digital signal conditioning and achieve very high accuracies. They simultaneously provide a digital I²C bus interface plus an analog 0.5 to 4.5 V output signal. This allows OEMs 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. The 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), they 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 sensors can be modified with respect to pressure range, resolution and internal digital settings in order to fit customers’ requirements. Typical applications include medical devices, instrumentation, environmental controls and HVAC.
