Description
Technical field
The utility model relates to a kind of sensor, is specifically related to a kind of magnetoelectric tachometric transducer.
Background technology
Existing magnetoelectric tachometric transducer, its coil is wrapped on magnet steel or the soft iron, and coil is direct and wire bonds, and manufacture craft property is lower.The sensor reliability of this structure is lower, and under vibration or impact condition, its inner structure is fragile.In addition, the inductive probe of speed probe exposes in outside, and probe has the slit with the junction of housing.When the measured body fault caused actual work temperature to exceed normal temperature range, the state of sensor Embedding Material can change, and by the solid-state liquid state that becomes, liquid Embedding Material can outwards flow out along the slit, is dropped on the measured body, polluted even the damage measured body.Because Embedding Material is amorphous material, use speed probe can make Embedding Material that rheology slowly takes place for a long time even overflow, there is potential safety hazard.
Summary of the invention
The utility model technical matters to be solved is to overcome above-mentioned deficiency, and a kind of magnetoelectric tachometric transducer is provided, and this sensor construction is simple, has improved the reliability and the manufacture craft property of speed probe, safety in utilization that can be under rugged surroundings.
The technical scheme of the utility model: a kind of magnetoelectric tachometric transducer, it mainly comprises soft iron, magnet steel, housing, coil, skeleton, contact pin, Embedding Material, skeleton is provided with soft iron and contact pin; Soft iron, contact pin and skeleton are whole; The groove of skeleton is provided with coil, and coil is connected with contact pin, and magnet steel is arranged on the skeleton; The sealing of housing one end; The arranged outside of the other end has screw thread, and soft iron, magnet steel, coil, skeleton, contact pin are arranged on enclosure interior and fix through Embedding Material, and insulator is arranged on the inner chamber of housing.
The another kind of technical scheme of the utility model: a kind of magnetoelectric tachometric transducer, it mainly comprises soft iron, magnet steel, housing, coil, skeleton, contact pin, Embedding Material, skeleton is provided with soft iron and contact pin; Soft iron, contact pin and skeleton are whole, and the groove of skeleton is provided with coil, and coil is connected with contact pin; Magnet steel is arranged on the skeleton, the sealing of housing one end, and the arranged outside of the other end has screw thread; Soft iron, magnet steel, coil, skeleton, contact pin are arranged on enclosure interior and fix through Embedding Material; Nut is threaded with housing, and sealing is stifled to be arranged in the hole of nut, and lead passes to seal to block up and is connected with the contact pin other end.
The utility model compared with prior art has following beneficial effect: 1, the utility model is simple in structure; Skeleton, soft iron and the contact pin of speed probe are made as one; Not only can improve the manufacturability of making, can also improve the reliability of speed probe under vibration, impact condition.2, the Embedding Material of stating speed probe is enclosed in enclosure interior, has realized isolation with measured body and surrounding environment.The change of Embedding Material state when the slow rheology of Embedding Material and measured body fault can not exert an influence to measured body and surrounding environment, thereby has strengthened the safety in utilization of speed probe.3, be applicable to the measurement of vehicular engine rotating speed and turbo charger speed, and use under the severe environmental conditions.
