Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a multifunctional integrated sensor. Background Technique

[0002] At present, the detection of water pressure, water flow and water temperature in the water supply system is essential. By detecting the water pressure, it can be ensured that the pipeline system will not burst or leak due to excessive pressure, thus avoiding potential safety hazards. The water flow detection helps to evaluate the operation efficiency of the system, ensure the smooth flow of water, and avoid system failures caused by poor water flow. The detection of water temperature is crucial for ensuring the comfort of user water use. For example, in a heating system, appropriate water temperature can provide a comfortable heating effect, while too high or too low water temperature may lead to poor system operation and affect the user experience. Therefore, detecting water pressure, water flow and water temperature can ensure the safe operation of the system, guarantee user comfort and health.

[0003] However, water pressure, water flow and water temperature generally need to be detected by separate pressure sensors, water flow sensors and temperature sensors. Installing multiple sensors in the water supply system has a high cost and is troublesome for inspection and maintenance. Therefore, we propose a multifunctional integrated sensor. Content of the Utility Model

A Hall element is installed inside the sensor body above the impeller, and the Hall element is connected to the rotor;

[0007] A pressure sensing element, the pressure sensing element is installed inside the sensor body on one side of the Hall element, and the bottom end of the pressure sensing element extends into the detection cavity;
