Title:
TOTAL DISSOLVED SOLID SENSOR WITH DYNAMIC GAIN
Document Type and Number:
WIPO Patent Application WO/2017/190303
Kind Code:
A1
Abstract:
A method includes operations of measuring total dissolved solids (TDS) in a liquid sample to provide a measurement signal, amplifying the measurement signal using a programmable gain amplifier to provide an amplified signal representative of the measurement, converting the amplified signal to a digital signal, if the digital signal is outside an adjustment range, adjusting the gain of the programmable gain amplifier and repeating the measuring and amplifying operations, and responsive to the digital signal being within the adjustment range, calculating a result signal based on the digital signal, the result signal being indicative of a concentration of the TDS.
