| GENERAL DESCRIPTION
|
| Sensortechnics’ HCE sensors offer precision pressure measurement from
10 mbar up to 5 bar. The HCE series performs precision digital signal conditioning to achieve ultra high total accuracies. An internal ASIC compensates sensor offset, temperature effects and non-linearity to allow for an excellent Total Error Band (TEB) better than ±0.5 %FSS. The pressure sensors provide digital interfaces with SPI bus protocol as well as analog output signals. Optional 3 V supply voltage versions and special low power devices make the HCE series ideal for battery powered applications, e.g. in portable or handheld devices. Miniature SMT housings with straight or barbed pressure ports allow for highly flexible OEM designs and space-saving PCB-mounting.
