The invention discloses a novel graphite sampling electro-mechanical conversion device. The device comprises an elastic compression device and graphite; a sliding contact tank for enabling the graphite to power on or off is closely arranged at an outer wall of the graphite, and one end of the graphite is connected with a counter head pulley for driving the graphite to rotate; a printed circuit board is welded at one end of the sliding contact tank, and the printed circuit board is connected with a main control circuit board through a sampling connecting line. The compression device at one endof a rotating shaft of the counter head pulley, the graphite is embedded into the compression device, the graphite and the sliding contact tank are in contact arrangement, the printed circuit board iswelded at one end of the sliding contact tank, and the printed circuit board is connected with the main control circuit board through the sampling connecting line, so that the rotation of the rotating shaft of the counter head pulley can drive the elastic compression device and the graphite embedded into a spring or a metal shrapnel to rotate, a mechanical signal can be converted into an electricsignal so as to realize the electro-mechanical conversion function.
Description
Technical field [0001] The present invention relates to a gas meter technical field, particularly to a novel graphite sample electromechanical conversion device. Background technique [0002] Gas meter has a social life in a very wide range of applications, on the one hand, the ordinary household diaphragm gas meter, because of its hard charging, meter reading personnel high labor costs, gas theft can not really achieve control, to gas companies continue to increase operating costs , it also brings a lot of trouble to the operation and management; on the other hand, with the improvement of people's living standards and quality of life, the need for modern family intelligent product demand, the gas meter is also moving in safety, reliability, ease of intelligence development. [0003] Currently, the common intelligence diaphragm gas meter on the market, there are two metering electromechanical conversion device converting mechanical counter mode: one way is to use reed is, the oth...
