Abstract
The utility model relates to an inserted electromagnetic flowmeter sensor, which can solve the problem of measuring error caused by the inconformity of the pipeline specified when leaving factory and the actual use pipeline of the similar products, comprising an electric pole, coils and a sheath. The utility model is characterized in that two groups of coils are respectively arranged on two sides of the electric pole, and a shielded sleeve is provided between the coil and the sheath. Because the shielded sleeve has the function of stabilizing the magnetic field, the installation of inserting type of the utility model can not cause inaccurate measure for the difference from the diameter of the pipeline used on scene and the pipeline of specified, and then the inserted electromagnetic flowmeter sensor of specified can be produced by the specified device with small caliber and small flow. The utility model is particularly suitable for the flow measurement of the pipeline of the diameter larger than 150 millimeter, and the perforating, installation and teardown can be implemented online by using correlative tools without stop production, cutoff, emptying and cutting pipe, so great engineering construction can be reduced, and the building cost of projects can be reduced, especially for the flow measurement of the network of the pipeline of feeding and draining.
Description
Technical field: the utility model relates to a kind of inserted electromagnet flow meter sensor.
Background technology: electromagnetic flowmeter is made up of sensor and converter two large divisions, converter wherein provides field power supply to make it produce magnetic field to sensor, measured medium produces induced potential because of the cutting magnetic line that flows, sensor electrode is given converter with the induced potential signal feedback, become standard signal output through the converter processing and amplifying, finish the measurement of flow.According to faraday electromagnetic induction, induced potential is directly proportional with magnetic field intensity, conductor length and movement velocity, because when a fixing pipeline is carried out flow measurement, its " conductor length " can be considered certain, have only when magnetic field intensity one timing, induced potential can be corresponding one by one with velocity of medium.If magnetic field intensity changes, even induced potential also can change under identical flow velocity, so just must bring following problems: the sensor of existing inserted electromagnet flow meter, the sensor of the various inserted electromagnet flow meters that use in CN2202916Y disclosed " sensing device of inserted electromagnet flow meter " and CN2447733 disclosed " a kind of electromagnetism fluid-velocity survey sensing probe " and the actual life for example, they all have a common defective, be the calibration value of product when dispatching from the factory, when taking on-the-spot the installation, deviation often appears, this has just brought very big trouble to the user, often need the scene to reset, trace it to its cause and just be: the magnetic field of inserted electromagnet flow meter sensor is open, the magnetic line of force around the electrode distributes uncertain, cause the scene and the timing signal magnetic field intensity of dispatching from the factory inconsistent, so on-the-spot the needs demarcated again.
The utility model content:
The purpose of this utility model is, at above-mentioned defective, a kind of inserted electromagnet flow meter sensor is provided, this sensor has stable magnetic field, therefore its induced potential intensity can not change because of sensor line size of living in changes, and self the widely-used convenience that provides is provided.
Technical solution of the present utility model is: a kind of inserted electromagnet flow meter sensor, comprise electrode, coil and sheath, and it is characterized in that: between coil and sheath, be provided with bell housing.
Aforesaid sensor can set up two groups of coils in the both sides of electrode separately.
Compared with prior art, because the setting of bell housing, having shielded sensor sidewall magnetic field on every side exposes, avoided under the different tube diameters condition by the magnetic field intensity difference around the electrode, realized the stable of sensor magnetic field, therefore the electric potential signal that sensor detected is only relevant with velocity of medium, has guaranteed that sensor extracts the uniqueness and the accuracy of flow information.That is to say that because of this bell housing has played the effect of stabilizing magnetic field, so the calibration value when plug-in installation of the present utility model can not influence product export, just thoroughly having solved prior art exists aforementioned disadvantages for this.Facts have proved, when the utility model is adorned in choosing at the scene, need not carry out on-site proving, thereby guarantee the accuracy and the reliability of product.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment: as shown in the figure, the inserted electromagnet flow meter sensor that the utility model provides mainly is made up of electrode 1, coil 2 and sheath 3 etc., and it is characterized in that: the coil 2 here has two groups, be located at the both sides of electrode 1 respectively, and between coil 2 and sheath 3, be provided with bell housing 4.The effect of coil 2 is to produce magnetic field, and the effect of electrode 1 is to detect induced potential, and they have lead to be connected with converter by sensor respectively; Bell housing 4 maskable sensors sides Distribution of Magnetic Field play the effect that makes magnetic field stable.The utility model is specially adapted to the flow measurement of diameter greater than the 150mm pipeline, this flowmeter need not stop production, cutout, emptying, disconnected pipe, use related tool can realize online perforate, installation, dismounting, can reduce a large amount of engineering constructions, reduce construction costs, especially be suitable for the flow measurement of confession, drainage pipeline networks.
