Description
Technical Field
The utility model relates to a load display system of oil electron weight indicating meter, in particular to pointer type electron weight indicating meter zero positioning mechanism.
Background
The weight indicator currently used in the petroleum industry is divided into two types, one is a mechanical mode and the other is an electronic mode. The mechanical weight indicator has the phenomenon that the pointer cannot return to zero after being used for a period of time, so that zero point errors and test errors are large. The zero point of the pointer type electronic weight indicator can be realized only by manual intervention. There are complaints from field users for both of these situations. Therefore, a pointer type electronic weight indicator capable of automatically and accurately determining the zero point position is urgently needed in the market.
Disclosure of Invention
The utility model aims at providing a novel pointer type electron weight indicator zero point positioning mechanism, both satisfied the requirement at user's automatic determination zero point, also can guarantee the accuracy of its test simultaneously.
The technical scheme of the utility model is that:
the zero point positioning mechanism of the pointer type electronic weight indicator comprises two springs, a spring fixing circuit board and a sensing circuit board; the method is characterized in that: the spring fixing circuit board and the sensing circuit board are respectively fixed on a dial plate bottom plate of the electronic weight indicating meter, the two springs are respectively fixed on the spring fixing circuit board, the spring fixing circuit board is connected to the sensing circuit board through a conducting wire, the sensing circuit board is connected to the motor through a conducting wire, the first spring can only be in contact with the weight indicating pointer, and the second spring can only be in contact with the sensitive pointer.
The specific implementation mode of the zero point positioning mechanism of the pointer type electronic weight indicator is as follows: the position of the spring is the load zero point, when the instrument is started, the motor drives the movement to rotate under the action of the control signal, so that the weight indicating pointer and the sensitive pointer are driven to rotate, in the rotating process, when the weight indicating pointer and the sensitive pointer are simultaneously contacted with the two springs on the spring fixing circuit board, the spring fixing circuit board transmits signals to the sensing circuit board through the conducting wires, the sensing circuit board receives two low-level signals, the sensing circuit records the rotating position of the motor at the moment, and the position is used as the zero point position of the motor in future.
The utility model has the advantages that: the zero point of the pointer type electronic weight indicator is automatically determined, and the accuracy is high.
