Abstract
The utility model discloses a resistance-type remote-transmitting pressure gauge. The resistance-type remote-transmitting pressure gauge comprises a pressure gauge, a gear drive device arranged in the pressure gauge, a slide wire resistor apparatus and a pressure transmitting circuit board. The slide wire resistor apparatus is arranged on the gear drive device. The pressure transmitting circuit board is electrically connected with the slide wire resistor apparatus. The pressure gauge of the utility model has the following advantages that: the pressure gauge possesses a high corrosion resistance property; real-time synchronization of a field and remote transmission data can be realized; the structure is simple and cost is low.
Description
Technical field
The utility model relates to a kind of pressure measuring instruments, relates in particular to a kind of resistance-type teletransmission tensimeter that steel or corrosion of copper alloy or pressure mediums such as incorrosive liquid, gas are measured that is applicable to.
Background technology
Mechanical pressure gauge is mainly used in the pressure medium of liquid, steam and the gas of measure field.Pressure unit mainly is responsible for the collection site analog signals, and is sent to digital display meter in real time, after analog quantity digitizing conversion, is sent to master system through PLC, supplies control center's monitoring.Prior art mainly adopts the combination of mechanical pressure gauge and capacitance pressure transmitter to observe pipeline pressure.The design of this split can be best take into account pipe safety; Be widely used, As time goes on, the shortcoming of this type combination also manifests gradually; The decay resistance that at first is pressure unit is relatively poor; Next is that split-type design tends to make pipeline to produce scene and two kinds of different pressure datas of host computer, brings potential safety hazard to production scheduling, is exactly repair and maintenance process relative complex at last.
The utility model content
The utility model provides a kind of high corrosion resistance that has in order to overcome the deficiency of prior art, can realize the resistance-type teletransmission tensimeter of the real time synchronization of on-the-spot and teletransmission data.
To achieve these goals; The utility model adopts following technical scheme: a kind of resistance-type teletransmission tensimeter; Comprise tensimeter and the cogwheel gearing of being located in the tensimeter; Also comprise slide wire resistance device and pressure inverting circuit board, said slide wire resistance device is located on the cogwheel gearing, and said pressure inverting circuit board is electrically connected with the slide wire resistance device.
As preferably, said slide wire resistance device comprises a variable resistor and slip transmitter.
As preferably, said variable-resistance resistance is 30 Ω-400 Ω.
The beneficial effect of the utility model is: the utlity model has high corrosion resistance, can realize real time synchronization on-the-spot and the teletransmission data, and simple in structure, with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
As shown in Figure 1; A kind of resistance-type teletransmission tensimeter; Comprise tensimeter 1 and cogwheel gearing 2, slide wire resistance device 3 and the pressure inverting circuit board 4 be located in the tensimeter 1, slide wire resistance device 3 is fixed on the cogwheel gearing 2, and pressure inverting circuit board 4 is electrically connected with slide wire resistance device 3.The slide wire resistance device comprises a variable resistor and slip transmitter, and the slip transmitter is fixed on the cogwheel gearing.Variable-resistance resistance is 30-400 Ω, and selecting resistance in the present embodiment for use is the variable resistor of 30 Ω.Principle of work: when the sector shaft in the gear drive produced deflection, the brush of slide wire resistance device also correspondingly passed partially, because brush slides on resistance; Make the variation of tested force value be transformed to the variation of resistance value, and the adjusting and the amplification of process pressure inverting circuit board, convert the current signal output of 4-20mA to; Recorded current signal value change reach on the secondary instrument after; Can show a corresponding force value, simultaneously, primary instrument also indicates corresponding force value; This pressure inverting circuit board is of a size of 5cm*3cm, just guarantees and can in mechanical pressure gauge, install.The utility model resistance-type teletransmission tensimeter is simple in structure, with low cost, and corrosion resistivity is high, can realize real time synchronization on-the-spot and the teletransmission data, and it is high to upload the data accurate rate.
