Abstract
The utility model discloses a dry reed type liquid level sensor; the dry reed type liquid level sensor comprises a guide bar and a floating ball which is freely sleeved on the guide bar; the surface of the guide bar is provided with a signal wire; the upper end of the signal wire is arranged in a junction box and the lower end is connected with a dry reed connection point on the guide bar. The sensor has a simple structure and is convenient to use; when a little water or no water is transmitted along the tap water pipe network and the liquid level drops in a water supply device, the useless work of a water pump can be ensured to stop; therefore, the energy is saved and the equipment is protected.
Description
Technical field
The utility model relates to sensor technical field, relates in particular to a kind of dry-reed type liquid level sensor.
Background technology
The supply equipment of tap water is connected when using on the municipal network water supply; Less or stop between delivery period when the pushing quantity of city planting ductwork, the decline of water table in the current stabilization jar, but water pump is still in work; Cause burn-down of electric motor easily, increased the use maintenance cost in the time of the waste resource.
The utility model content
The utility model provides a kind of dry-reed type liquid level sensor in order to solve the problems of the technologies described above.
The technical scheme that the utility model adopts is: a kind of dry-reed type liquid level sensor comprises guide rod and the freedom suit ball float at this guide rod; Said guide rod surface is provided with signal wire, and the upper end of signal wire is arranged in the terminal box, and the lower end is connected on the dry-reed contact on the guide rod.
Preferably, also be arranged with hold-down nut and location clip on the said guide rod.
Simple in structure in the utility model, easy to use, few or cut off the water when tap water pipe network pushing quantity, during decline of water table in the supply equipment, can guarantee that water pump stops useless work, energy savings protection equipment.
