Hydrostatic pressure produced by the water column at the bottom of the controlled liquid reservoir uses the trapped air in the measurement tube to produce the same amount of pressure on the sensor. At ...
The PuffinPLC Project is an effort to produce a Linux-based GNU Public Licensed Programmable Logic Controller (PLC). PLCs were developed in the 1960s to replace the complex electrical relay circuits ...
This reference design describes a cost-effective, low-power liquid-level measurement data acquisition system (DAS) that use a compensated silicon pressure sensor and a high-precision delta-sigma ADC.
