New Miniature HCE Pressure Sensors Offer Digital SPI Output Signals and High Accuracy

摘要

Sensortechnics' (Germany) new HCE series offers precision pressure measurement from 10 mbar up to 10 bar. The HCE sensors perform digital signal conditioning to provide highly accurate digital and analog output signals. They comply with the SPI bus protocol and can directly communicate with microcontrollers and microprocessors. I2C bus, switching or custom specific outputs are available on request. The HCE series utilises the latest ASIC technologies to achieve high total accuracies, with an excellent Total Error Band (TEB) better than ±0.5 %FSS, including all temperature effects. A 3 V supply voltage and special low power versions (optional) make these sensors ideal for battery powered portable device applications. Miniature SMT housings (DIP and SIL versions on request) with straight or barbed pressure ports allow for highly flexible OEM designs and space-saving PCB-mounting. For all HCE pressure sensors Sensortechnics can provide fast and flexible modifications based on custom specific requirements.
