For the pressure switch device, when the shifting lever and traverse lever contact, the burn-out phenomena due to the high-voltage transient AC current is avoided, thereby forming the pressure meter with switch-on/-off function.
Description
Technical field
The present invention provides a kind of tensimeter with current transfer device, refers to especially a kind ofly can convert the High Level AC Voltage of input to low-voltage DC, thus, with the tensimeter of avoiding ablating and producing with the carbon deposit phenomenon with current transfer device.
Background technology
The activation that the pressure that utilizes tensimeter to record is high and low to be used as relevant apparatus with close, for industry for a long time extensively the utilization technology (as: air compressor machine), but, doing further analysis at its structure can learn, it is provided with a touch sensor respectively more than manometric high-pressure side and low-pressure side greatly, further sensing is judged the position of manometric pointer, is used as activating or closing the foundation of relevant apparatus.
And the TaiWan, China of just checking and approving with the previous application of this creator among the present invention is announced No. 463947 " having the tensimeter structural improvement of switching function concurrently " explanation, see also Fig. 1 figure and shown in Figure 2, it has a tensimeter 9, this tensimeter 9 has a panel 91 that is provided with scale, on this panel 91 and have one and can do rotation or the pointer 92 that makes zero with pressure change, and, high-pressure side and low-pressure side at this tensimeter 9 are to be respectively equipped with a high-voltage contact 93 and a low-voltage contact 94, and aforesaid height, low- voltage contact 93,94 more are respectively equipped with a driven member 931 and 941, wherein high, low- voltage contact 93,94 is same input power supply also, and two driven members 931,941 is each other input power supply, therefore, this tensimeter 9 is formed with the power lead 95 of three inputs, 951,952; And by above-mentioned combination, make when the pointer 92 of this tensimeter 9 upwards rotates because of pressure rises, it is the driven member 941 that can pass through low-voltage contact 94 earlier, rotate and stir a fin 942 that is hubbed at driven member 941, this fin 942 is contacted with low-voltage contact 94, and the state of formation conducting, advance to activate the running of relevant apparatus (not shown), and if when pressure continues to rise and allow this pointer 92 through high-voltage contact 93, this pointer 92 is that the fin 932 that can stir the driven member 931 that is hubbed at high-voltage contact 93 rotates, when making these fin 932 these high-voltage contacts 93 of contact, allow this driven member 931 and high-voltage contact 93 form the state of conducting, to stop the running of this relevant apparatus, so, to form of the function design of a kind of tensimeter with switch.
Can learn via above-mentioned explanation, it is to utilize pointer 92 to stir fin 932 or 942, make the fin 932 or 942 formation conducting state that contacts with high pressure or low- voltage contact 93 or 94, advance with control relevant apparatus activation or stop, but, because driven member 931,941 with high, low-voltage contact 93, the 94th, linking respectively has a power lead 951,952, and make each driven member 931,941 with high, low- voltage contact 93,94 all become to have the state of High Level AC Voltage, therefore, when fin 932,942 touch height, low- voltage contact 93,94 moment is can be because of the moment conducting of High Level AC Voltage have the generation of spark, and the high temperature of this spark when producing is to cause fin 932,942 with high, low- voltage contact 93,94 or pointer 92 have the phenomenon of ablation to produce.
In view of this, this creator is the tensimeter structural improvement that has switching function concurrently at above-mentioned previous creation, having high temperature causes the problems such as ablation of spare part deeply to inquire into, and actively seek solution, research and development through long-term endeavour, finally success develop a kind of " tensimeter " with current transfer device, it can effectively eliminate the ablation phenomen that spark caused in the past, but more practice in contact and noncontact sensing apparatus.
