The water temperature and water level sensor is composed of a thermostat part and a water level control part, and a pressure relief device in front of an electric valve and a rotary muffler heater for heating are matched with it
The water level sensor in the container transmits the sensed water level signal to the controller. The computer in the controller compares the measured water level signal with the set signal to obtain the deviation, and then sends it to the water supply electric valve according to the nature of the deviation. Turn on the "off" command to ensure that the container reaches the set water level. After the water inlet procedure is completed, the computer in the temperature control part issues an "open" instruction to the electric valve that supplies the heat medium, and the system begins to heat the water in the container. When the set temperature is reached. Only after the controller issues the command to close the valve and cut off the heat source, the system enters the heat preservation state. In the process of programming, to ensure that the system does not reach the safe water level, the electric control valve that controls the heat source does not open the valve, thereby avoiding heat loss and accidents.
