This is a simple water level detection sensor that integrates a drive circuit to determine the presence or absence of moisture based on the resistance value between the comb-shaped electrode sensor and the comb-shaped electrode.
The warning water level detection device "AKI-1805" integrates a heater-equipped comb-shaped electrode sensor to improve malfunction caused by humidity and condensation, along with a drive circuit that determines the presence of rain based on the resistance value between the comb-shaped electrodes. Since the sensor and drive unit are integrated, there is no need to create surrounding circuits, making it easy to handle. The sensor is heated by the heater, which improves malfunction caused by humidity and condensation. After being immersed in 1% seawater, the humidity test results (with the sensor surface in a dirty state) show normal operation at 90% humidity, with characteristics improved by 10% compared to without the heater (manufacturer comparison), and the built-in heater accelerates the drying of the sensor surface. Due to low voltage and AC drive, corrosion from electrolysis of the comb-shaped electrodes (sensor) can be suppressed. For more details, please contact us or download the catalog.
