[0002] At present, when conducting cement performance tests, it is necessary to maintain the tested cement blocks in a constant temperature and humidity environment for a certain period of time, generally at 20°C and 92% relative humidity, and then do various tests; in the curing room, generally use a spray humidification device For maintenance, the spray water is recycled. Due to the continuous consumption of water, it is necessary to replenish the reservoir in the maintenance room with external water through the tap water pipe. At present, a float valve is often used to automatically control the water level of the pool; due to poor water quality and alkaline water Float valves are often damaged due to high temperature and high operating frequency, causing water shortage or overflow accidents. Although there are devices in other industries that use electrode positions to automatically control water levels, most of them are not suitable for high-humidity environments and do not meet high reliability requirements. performance requirements, and the cost of existing control devices is relatively high, which is not suitable for wide application
