The utility model technical issues that need to address provide a kind of level sensor to reach the measuring accuracy height, the purpose that reliability is high.
For the technical scheme that solves the problems of the technologies described above the utility model is, a kind of level sensor comprises a kind of level sensor; Comprise bonnet, protecgulum, bonnet is provided with joint; Be provided with pressure chamber in the bonnet, pressure chamber communicates with joint, and described pressure chamber has the diaphragm with the pressure chamber sealing; Diaphragm has push rod, is provided with variometer in the described protecgulum, and push rod is connected with the magnetic core of variometer.
Described variometer is by magnetic core, the magnetic cap, and potted coil is formed, and described potted coil is arranged on the protecgulum, and described magnetic core is arranged in the protecgulum, and described magnetic cap sleeve is connected on outside the magnetic core, and described magnetic cap is connected with protecgulum through spring.
Described bonnet is connected with protecgulum through iron ring, base, and an end of push rod is connected with base, and the other end is connected with magnetic core.
Also be provided with support, swivel nut, base support on the described protecgulum.
Described magnetic cap is vertical with push rod to be provided with.
The utility model compared with prior art is provided with pressure chamber in the bonnet, pressure chamber communicates with joint; Described pressure chamber has the diaphragm with the pressure chamber sealing; Diaphragm has push rod, is provided with variometer in the described protecgulum, and push rod is connected with the magnetic core of variometer.Directly do not contact with liquid, link to each other with fluid to be measured through U type pipe unit and measure accurately and reliably, the precision of measurement is high, and simple in structure, safe in utilization.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details;
Fig. 1 is the utility model structural representation
In Fig. 1,1, bonnet, 2, diaphragm, 3, push rod, 4, iron ring, 5, base, 6, magnetic core, 7, the magnetic cap, 8, potted coil, 9, spring, 10, support, 11, swivel nut, 12, base support, 13, protecgulum.
Embodiment
Contrast accompanying drawing below; Through description to embodiment; To effect and principle of work, the manufacturing process of the mutual alignment between the shape of the embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc.; Do further detailed explanation, utility model design, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art.
A kind of level sensor comprises bonnet 1, protecgulum 13; Bonnet 1 is provided with joint, is provided with pressure chamber in the bonnet 1, and pressure chamber communicates with joint; Described pressure chamber has the diaphragm 2 with the pressure chamber sealing; Diaphragm 2 has push rod 3, is provided with variometer in the described protecgulum 13, and push rod 3 is connected with the magnetic core 7 of variometer.
Described variometer is by magnetic core 6, magnetic cap 7, and potted coil 8 is formed, and described potted coil 8 is arranged on the protecgulum 13, and described magnetic core 6 is arranged in the protecgulum 13, and described magnetic cap 7 is socketed in outside the magnetic core 6, and described magnetic cap 7 is connected with protecgulum 13 through spring 9.
Described bonnet 1 is connected with protecgulum through iron ring 4, base 5, and an end of push rod 3 is connected with base, and the other end is connected with magnetic core 6.
Also be provided with support 10 on the described protecgulum, swivel nut 11, base support 12.
Magnetic cap 7 and push rod 3 vertical settings, magnetic core 6 can move up and down along coil 8, and magnetic core 6 contacts with push rod 3; Protecgulum 13 is provided with potted coil 8, when air pressure when joint enters into pressure chamber, the pressure in the pressure chamber rises; Pressure compression diaphragm 2 in the pressure chamber is to lower recess, and the push rod 3 under the diaphragm 2 moves downward drive magnetic core 6 and moves downward, when the pressure of joint diminishes; Pressure in the pressure chamber diminishes, and magnetic core 6 moves upward under the effect of spring 9; At compressing push rod 3, magnetic core 6 moves upward along coil diaphragm 2, and the moving up and down of push rod 3 changes the distance of magnetic core 6 and potted coil 8 so that potted coil 8 is exported different inductance value.Level sensor links to each other with fluid to be measured through U type pipe unit and measures accurately and reliably.
The joint of level sensor is connected with water tank, and when water level was in high water stage when water tank water intake, the pressure of pressure chamber rose; Pressure compression diaphragm 2 in the pressure chamber is to lower recess, and the push rod under the diaphragm 2 moves downward drive magnetic core 6 and moves downward, envelope switch coil 8 output high water stage inductance value; When water level was in low-water level when water tank discharges water, when the pressure of joint diminished, the pressure in the pressure chamber diminished; Magnetic core 6 moves upward under the effect of spring 9, and diaphragm 2 is not at compressing push rod 3; Magnetic core 6 moves upward along coil; Potted coil 8 output low-water level inductance value, level sensor is according to the different different inductance value of water level output, and controller is confirmed the water level of water tank according to the inductance value that receives.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technical scheme is carried out; Or directly apply to other occasion without improvement, all within the protection domain of the utility model.
