Liquid level sensor |
摘要 |
A sensor system. The system comprises a binary sensor issuing a signal representative of a first or second condition; sampling circuitry, operatively connected to the binary sensor, for monitoring the number of transitions between the first and second conditions during a sampling period; integration circuitry for accumulating the sampled number of transitions over time; and signal generation circuitry for issuing an analog signal representative of the accumulated transitions.
