Ratemeter and monolithic integrated circuit

The traditional automobile rotational speed odometer's function has two; first, with indicator instruction automobile travel instantaneous vehicle speed; second, records the automobile travel with the mechanical counter the accumulation course. The modern automobile is developing to the high speed direction, along with the vehicle speed enhancement, the tradition speedometer which actuates with the flexible axle receives the unprecedented challenge, this is because of the flexible axle when high speed revolving, as a result of steel wire alternate stresses limit limit, but easy to break, simultaneously, the flexible axle will arrange long will have presented the deformation oversized or the movement sluggish and so on phenomena, moreover, regarding the different vehicle type, the rotational speed odometer's installment position will also receive the flexible axle length and bending limit. All these, causes based on the non-contact type tachometer generator's electronic formula rotational speed odometer to be able the rapidly expand.

Present's automobile measuring appliance automaticity is very high, what the old style mechanical flexible axle transmission's measuring appliance already eliminated displaces is present's liquid crystal gauge board, is impossible through to dial the digital code wheel adjustment odometer again. When in the driver needs to increase the number of passes, runs the table with this kind to be possible very with ease to

realize. This kind runs the table use medium scale integration design to become, the volume is exquisite, the movement is stable, is suitable uses on each kind of electronic transducer's automobile. This kind of exquisite instrument has compared to the other similar products obvious merit: 1st, the circuit design is exquisite, strict. Has used the high performance integrated circuit and the electronic component, the guarantee circuit has the high quality; The use optimization's circuit design, considered many disadvantageous use environment, enable the instrument as far as possible in the voltage, the temperature, the humidity, the dust pollution and so on under complex change factor many conditions to be able the steady work. 2nd, the reliability is good. In order to enhance the electric circuit work the

reliability, not only the part passes through screens carefully, moreover passes through 2400 hours to roast machine the experiment, its outer covering is exquisite, may install conveniently in the pocket, momentarily may take the use. 3rd, simplicity of operator, easy to operate. Only needs to insert to the cigar lighter on, does not need to get out, all OK. 4th, the use security, felt relieved. Even if meets instead, also will not damage the instrument, will not damage on the vehicle anything. 5th, the speed may adjust. You may the speed

regulation highest, may also adjust to a fixture, for instance 300 step. Is different based on the vehicle type, the speed differs from, may the speed knob change speed through the regulating instrument on.
