An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity (RH) sensor. Some RH sensors have a transfer function of capacitance vs %RH. Usually the ...
Nowadays, humidity measurement is important for various applications in the industry. Humidity sensing is applied in automotive, medical and healthcare, HVAC, t&m, food storage and refrigeration, and ...
Devices that measure relative humidity (e.g., sensors and transmitters) play a relatively small role in cleanroom management, but their failure can cause significant problems. Operators should bear ...
As discussed in the first part of the article, the accuracy with which sensor capacitance can be measured using absolute capacitance measurement has a significant dependency on the accuracy of the ...
