Summary of the invention
The purpose of this utility model is that a kind of improvement on existing level sensor basis will be provided, and has high temperature resistant, the high humidity of energy, the strong good a kind of high-temp resisting high-humidity resisting level sensor of anti-oxidant, resistance to corrosion.
Technical characterictic of the present utility model is: considering stable performance, be designed to the high-temp resisting high-humidity resisting level sensor formed by electrode, insulation tube, connector, attaching nut, case, control panel, lead-in wire, O-ring seal on the basis that can high-temp resisting high-humidity resisting, connector connects adjacent insulation tube, and be provided with O-ring seal in the junction, be provided with electrode on connector, insulation tube topmost is connected with case; On case, be provided with the attaching nut; Control panel is arranged in the case, and lead-in wire is connected control panel respectively with each connector, and described electrode is that graphite composite material is compressed on the anti-oxidation electric conductor on the connector; Described insulation tube is high density ceramic material surface treated again ceramic pipe behind high temperature sintering.
Described electrode is that to be compressed on anti-oxidation electric conductor on the connector be to say that electrode is that graphite composite material is compressed on the connector and in its surface-coated through high temperature, high pressure anti-oxidant tight zone is arranged to graphite composite material.
Described insulation tube is that high density ceramic material surface treated again ceramic pipe behind high temperature sintering is to say that insulation tube adopts the repressed one-tenth ceramic pipe of high density ceramic compound substance, has high temperature resistant fine and close protective seam in its surface recombination again.
Described control panel is the control device that is used to control each termination electrode.
During use, the utility model high-temp resisting high-humidity resisting level sensor is inserted in the water tank of solar water heater, and is connected with the sensor mounting hole of solar water heater by the attaching nut.When water level changes, form the loop by electrode, and control by the resistance value of control circuit reflection, its signal is sent in the water level controller controls.The surface of electrode is provided with anti-oxidant tight zone, its objective is in order to prevent to cause easily that under humid tropical condition phenomenons such as fouling corrosion are provided with; Seal by high-temperature insulation glue between electrode and the insulation tube; . the inner high-temperature insulation glue that injects of insulation tube its objective is in order to play insulated enclosure setting; The insulation tube outside is provided with high temperature resistant fine and close protective seam and its objective is in order to prevent that pottery from corrosion taking place and seepage is provided with.
The utility model has the advantages that:, thereby make electrode have performance anti-oxidant, high temperature resistant, non-scaling because electrode adopts graphite composite material to make, and is provided with tight zone on its surface; Because insulation tube adopts the high density ceramic material to form through high temperature sintering, thereby makes the insulation tube dependable performance; Owing to be provided with high temperature resistant fine and close protective seam in the outside of insulation tube, the insulation tube ageing resistance is good, sealing is reliable thereby make; Because adopt high-temperature insulation glue to seal between electrode and the insulation tube, thereby make it be not easy to produce seepage, the performance of product is good; Owing to be provided with the attaching nut, thus being connected of convenient and solar water heater; Because dependable performance, easy to install, long service life are so there is very big practical and popularizing value.
