Abstract
The utility model discloses a sensing device, in particular to a liquid level sensor, comprising liquid level electrodes and common electrodes formed by graphite rods, wherein the liquid level electrodes and the common electrodes are connected by silica gel tubes which are internally provided with wires for connecting the liquid level electrodes and the common electrodes; and the wires are connected with external pulse current elements. The graphite electrodes have the advantages of oxidation resistance, corrosion resistance and difficult scaling, so that the service life of the liquid level sensor is prolonged; and silica gel caps do not need to be additionally arranged on the electrodes for sealing, therefore, the production link of the liquid level sensor is reduced and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of sensing device, the novel liquid level sensor that uses on especially a kind of solar water heater.
Background technology
At present, the liquid level sensor electrode of solar water heater generally adopts metal material to make, and long-time immersion easily causes the level electrode oxidized or water erosion in surface, the serviceable life of reducing level electrode in water tank.For some product in serviceable life that prolongs electrode has added silicon rubber cup at the electrode two ends, though played certain waterproof action, increased cost of products, and the complexity that production technology is become, cause the production efficiency of liquid level sensor low.
The utility model content
For overcoming above-mentioned technical matters, it is a kind of rational in infrastructure, less scaling that the utility model provides, the novel liquid level sensor of long service life.
For realizing above-mentioned technical purpose, the utility model is achieved through the following technical solutions: a plurality of level electrodes 1 connect one by silicone tube 2, last silicone tube 2 connects public pole 4, it is characterized in that level electrode 1 and public electrode 4 are columniform graphite rod, be provided with the lead 3 that connects level electrode 1, public pole 4 in the silicone tube 2, be filled with sealing silica gel in the cavity of silicone tube 2.
Described lead 3 is the stainless steel lead.
The level electrode 1 of described liquid level sensor, public pole 4 are provided with fluid sealant with the junction of silicone tube 2.
The utility model is compared with conventional art, has following beneficial effect: graphite electrode has anti-oxidant, anticorrosive, less scaling advantage, has prolonged the serviceable life of liquid level sensor; Need not to install silicon rubber cup additional on the electrode and seal, reduced the production link of liquid level sensor, improved production efficiency.
