Device for cleaning water quality sensors

Abstract

A sonde comprising a first sensor and a second sensor adjacent the first sensor, the first sensor including an optical window and a wiper element, the wiper element rotating on a shaft extending fromthe first sensor so as to clean debris from the window, a brush extending from the wiper element beyond the perimeter of the first sensor such that the brush contacts the adjacent second sensor and removes debris which accumulates on the second sensor.

Description

technical field [0001] The invention relates to a device for wiping a water quality sensor. Background technique [0002] Sensor devices or probes are used to monitor water quality. A detector may contain detectors or sensors to monitor several different water qualities, including turbidity, pH, dissolved oxygen, conductivity, temperature, salinity, and other possible water qualities. These appliances are generally made of optical instruments or electrical appliances. Monitoring may be inaccurate if light pathways and electrical connections become contaminated with dirt, fungal or algal growth. [0003] It is known in the art to equip such detectors with an optical window for monitoring therethrough to measure a function of reflectance, fluorescence, or another optical or photosensitive response. However, if detectors are deployed for long-term monitoring, a large amount of animal and plant pollution may accumulate on the sensors, making it impossible to monitor accuratel...
