The water level measuring sensor comprises a pressure sensitive element which can continuously measure and an application-specific integrated circuit connected with the pressure sensitive element. The water level measuring sensor is characterized in that the water level measuring sensor also comprises a sensor body of a guidance tube with a through hole and an output part connected with the body; the pressure sensitive element is fixed on the sensor body and is communicated with the guidance tube. The utility model adopts the pressure sensitive element and can continuously measure the variation of the water level. The water level value measured by the water level measuring sensor can be transformed into the digital quantity which is outputted. The water level measuring sensor can accurately and continuously measure the water level in time and has the advantages of anti-incrustation and high temperature resistant. The water level measuring sensor is suitable for measuring the water level of a square box pail or a round box pail.
Description
Technical field
The utility model belongs to field of measuring technique, particularly the improvement of level measuring sensor construction.
Background technology
In the use of water supply user water tank, in order to measure water consumption in real time and to realize manually or automatically adding water management.Newer level measuring technical method roughly has four kinds at present: a kind of is ball-cock assembly fixed point upper control limit water level.Shortcoming is to control top single-point water level.Second kind is the throw-in type pressure transducer.Shortcoming is owing to need in the input water sensor and lead sealing are cost an arm and a leg.And the water level range can not be adjusted.The third float-type transmitter.Its shortcoming is to place in the water tank, and is perishable, and the life-span is short; Be subject to incrustation scale and block, it is unreliable to work.The 4th kind of some water-temperature water-level measurement mechanism directly links to each other pressure transducer with water tank, and it is bigger that pressure signal output is influenced by water temperature.And scaling blocks the pressure transfer hole easily easily.
Summary of the invention
The purpose of this utility model is the deficiency at prior art, designs a kind of level measuring sensor, realizes in real time accurately continuous coverage water level, and anti-incrustation scale, high temperature resistant.
A kind of level measuring sensor of the utility model design comprises the pressure-sensing device that can carry out continuous coverage, and the special IC that links to each other with this pressure-sensing device; It is characterized in that also comprise a sensor body and an output block that links to each other with this body that has the guide wire of through hole, described pressure-sensing device is fixed on the sensor body, and communicates with guide wire.
The utility model adopts pressure-sensitive component to measure water level, has realized the continuous coverage of water level, and measurement range is big, and is highly sensitive, measures accurately; And anti-incrustation scale, anti-high water temperature.Compactness simple for structure, volume are little, and installation, maintenance is convenient.
The water level range of level measuring sensor described in the utility model can be adjusted arbitrarily according to the water tank height in working range.

Embodiment
The level measuring sensor of the utility model design reaches accompanying drawing in conjunction with the embodiments and is described in detail as follows:
Fig. 1 is a level measuring sensor construction embodiment synoptic diagram of the present utility model.The level measuring sensor body is a threeway 4.The threeway upper end connects a waterproof connector; The threeway lower end connects an antifouling plug 5.This threeway up and down two ends forms a vertical through hole as pressure guide hole 1, and the 3rd termination that forms an angle with vertical through hole is used for fixing pressure-sensitive component 3 and special measurement integrated circuit 2.
The utility model adopts the pressure-sensing device that can carry out continuous coverage, is used to measure SEA LEVEL VARIATION, and uses special IC that the Simulated Water place value is converted into digital quantity output; Described pressure-sensing device is fixed on the sensor body by cushion rubber, and the pressure-sensing device output signal is delivered to the circuit board at special IC place, and described circuit board is fixed on the sensor body, output digital water level signal; One of described three-port structure links to each other with water tank by the waterproof connector, and the other end is sealed with antifouling plug as sewage draining exit, and the 3rd links to each other with the level measuring sensor.
Pressure-sensing device described in the utility model can adopt output quantity can the continually varying capacitive transducer, inductance sensor, ceramic sensor element, crystal probe, semiconductor transducer, each sensor should have the water level range, and the water level range can be adjusted in working range.
Fig. 2 is the mounting means synoptic diagram of the utility model at water tank bottom.6-is for needing to install the water tank of level sensor, and 4-is a skew T, and 5-is the antifouling plug that places the threeway lower end, and 7-is the 3rd termination of fixation pressure Sensitive Apparatus; Among the figure, the 3rd termination 7 is inclined upwardly, and spends less than 90 greater than 0 degree with the angle of upper end.
The utility model when water tank bottom is installed with pressure-sensitive component by cushion rubber fixedly on the skew T, pressure-sensitive component is away from casing, in the water tank water temperature influence little, anti-high water temperature is measured accurately.Pressure-sensitive component tilts to be fixed on the skew T, and anti-incrustation scale performance is good.After dirt and incrustation scale fall, directly drop on the antifouling plug.Open once antifouling plug at regular intervals, do a blowdown and handle, therefore, the utlity model has the characteristics of long service life.
Fig. 3 is the another kind of mounting means synoptic diagram of the utility model at water tank bottom.With the difference of Fig. 2 structure be that the 3rd termination 7 is downward-sloping, with the angle of upper end greater than 90 degree less than 180 degree.
