Abstract
The utility model discloses a sensor excitation coil with high protection grade. The sensor excitation coil with the high protection grade comprises an electromagnetic coil, wherein a rubber insulation layer is coated outside the electromagnetic coil. According to the sensor excitation coil provided by the utility model, a layer of rubber insulation layer is coated outside the electromagnetic coil, and the rubber insulation layer is close to exterior of the coil, so that the coil is convenient to be arranged in a sensor; the rubber has elasticity, so that embossment of the excitation coil and a measured tube, and corrosion of a welding point are avoided; and after the coil coated with the rubber is placed into water, the insulation property of the coil is ensured effectively. The practical reliability of the sensor, in particular an immersion type sensor, is increased, and resin is not poured after the rubber layer is coated, so that the production process is simplified; and the sensor excitation coil with the high protection grade is particularly suitable for large- and medium-sized electromagnetic flow sensors with the caliber of more than DN200. The protection grade of the sensor excitation coil reaches IP68, namely adverse effects on various proprieties of the electromagnetic flow sensors are not caused when the electromagnetic flow sensors are immersed at 10 meters under the water and used in the water for a long time.
Description
Technical field
The utility model relates to a kind of sensor field coil, is specifically related to a kind of field coil of good insulating.
Background technology
The field coil of electromagnetic flow transducer is fixed on the measuring tube, and coil can not directly contact with the metal measuring tube, so this just requires field coil is done certain protection.The protection of tradition field coil be coil self dipping lacquer be wrapped on the coil with cotton tape or glass fiber varnish-treated tape or coil as for casting resin in the mould, be used for protecting the electromagnetic wire of coil not to be worn and guarantee its insulativity.Yet when being immersed in the water with the coil after cotton tape or the winding of glass fiber varnish-treated tape behind the dipping lacquer, can not guarantee its insulativity and sealing fully, and when on the metal measuring tube convexity or solder joint being arranged, also cause wearing and tearing easily.Cotton tape or glass fiber varnish-treated tape make coil exposed outside; Although coil is poured into a mould with mould, coil is embedded in the resin can effectively guarantees its insulativity, use the method for bigbore sensor; Increased the manufacturing cost of sensor greatly, and the coil after the moulding is not easy to install.
Background technology
The technical matters that the utility model will solve is the insulativity and poor sealing, cost height of existing field coil, and a kind of insulativity and good airproof performance, the high sensor field coil of degree of protection that cost is low are provided.
The technical scheme of the utility model realizes in the following manner: the sensor field coil that a kind of degree of protection is high, comprise solenoid, and solenoid is coated with rubber insulation.
Said rubber insulation is the neoprene insulation course.
The utility model has coated one deck rubber insulation outside solenoid; Rubber insulation is close to outside the coil; Be convenient to coil is installed in the sensor; Rubber is flexible, can avoid the convexity and the solder joint wearing and tearing of field coil and tested buret, and the coil behind the parcel rubber can place water effectively to guarantee its insulativity.Not only strengthen sensor and particularly immersed the practical reliability of type, and do not needed casting resin after the cladding rubber layer, simplified production technology, be specially adapted to the electromagnetic flow transducer of the above large and medium-sized specification of DN200 bore.Degree of protection reaches IP68, promptly is immersed in 10 meters under water, in water, uses the various performances to electromagnetic flowmeter to have no adverse effects for a long time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the elevational schematic view of Fig. 1.
Embodiment
Sensor field coil as depicted in figs. 1 and 2, that a kind of degree of protection is high comprises solenoid 1, and solenoid 1 is coated with one deck rubber insulation 2.Described solenoid is that field coil is entwined with cotton tape or glass tape behind dipping lacquer.
Said rubber insulation 2 is neoprene insulation courses, or the rubber layer of other good insulating, good springiness.
The utility model has made full use of the insulativity and the elasticity of rubber insulation 2, can in water, use for a long time.
Claims (2)
1. the sensor field coil that degree of protection is high comprises solenoid (1), it is characterized in that: solenoid (1) is coated with rubber insulation (2).
2. the sensor field coil that degree of protection according to claim 1 is high is characterized in that: said rubber insulation (2) is the neoprene insulation course.
