Description
Technical field
The utility model relates to a kind of sensor, the pawl formula sensor of the water level in the measurement water-heater water tank that uses on especially a kind of solar water heater and coolant-temperature gage.
Background technology
Present solar water heater is popularized in China comprehensively, and the sunshine-duration, long local every household, hotel, hospitals and other places all used the solar water heater hot-water supply, and solar water heater is widely used.In order to understand water level and the water temperature in the water heater, to be convenient in time to water on the sun power, the sensor of water level and water temperature has appearred measuring.The first-selected pawl formula of sensor most favored by customers sensor, yet through using, the pawl formula sensor life-time that is equipped with on a lot of sun power is short, because being temperature, the water in the solar water heater remains between the 80-100 degree, pawl formula sensor is easy to damage, and owing to distance between every pair of level electrode, the sensitivity of measuring water level is obviously descended.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the non-damageable long service life of a kind of measuring sensor and detection sensitivity high pawl formula water-temperature water-level sensor.
Pawl formula water-temperature water-level sensor of the present utility model, it comprises many level measuring bars, the cylindrical shell of circuit board having built-in, output line; Described many level measuring bars are fixed on the cylindrical shell, and are connected with wiring board by wire; Described every level measuring bar comprises metallic rod body and level electrode device, described level electrode device is a tubular metal body, described metallic rod body is hollow, thereby so that the wire that the level electrode device is connected with wiring board passes from metallic rod body and wire is built in the metallic rod body; Described level electrode device be positioned at metallic rod body the end and by insulating sleeve both isolation and level electrode device and metallic rod body socket connection namely one the jack that matches with another is arranged, insulating sleeve plays so that the effect that both junctions seal.
As preferably, in order to make metallic rod body and level electrode device better tightness, be provided with an insulation tube at level electrode device and metallic rod body, insulation tube and contacted level electrode device or metallic rod body form sealing, and described level electrode device and metallic rod body junction are arranged in insulation tube.
As preferably, grafting between described level electrode device and the metallic rod body is that the level electrode device inserts in the metallic rod body, the level electrode device place external diameter that is connected with metallic rod body cooperates with metallic rod body hollow tube internal diameter, and the external diameter of the level electrode device other end is identical with the external diameter of metallic rod body.
As preferably, described insulation tube and insulating sleeve all high temperature resistant and resilient rubber-plastics material consist of.
As preferably, described metallic rod body and level electrode device are that stainless steel material consists of.
For so that the line end of drawing of cylindrical shell does not seep water, be provided with enclosing cover at its extension line place, described enclosing cover be buckled in cylindrical shell draw line end and extension line is drawn from the side-walls of enclosing cover, avoided rainy day water to penetrate in the cylindrical shell.
Pawl formula water-temperature water-level sensor in sum has the characteristics such as easy to use, that cost is low.
