The mounting structure of the pressure transducer of another kind of flow transmitter discloses in the one Chinese patent application of Sailsors Instruments Co., Ltd. and the big co-applications of Ba Hong; The application number of this patented claim is 200620039515.3, title is a kind of multivariable transmitter of compound transducer; This flow transmitter changes the structure of advancing medium of former horizontal type into advance medium from the instrument bottom structure; And differential pressure pick-up upper and lower medium face vertically placed; Pressure transducer is placed in total cavity of flow transmitter, like this, setting is presented down with the pressure chamber that differential pressure pick-up is installed in the impulse chamber of setting pressure sensor.Though this flow transmitter have general structure simple with advantage such as appearance looks elegant, but havoc differential pressure pick-up former about the balance of constitutional balance and medium-weight influence of two cavitys, cause the precision and the repeated reduction of differential pressure pick-up.In addition, when medium after long-time running, can cause the deposition in instrument, cause accuracy of instrument to descend or lost efficacy.
Summary of the invention
The problem that the utility model solves be the mounting structure of the pressure transducer of existing multiparameter transmitter make the poor reliability of transmitter, precision is low, repeatability is low and the outward appearance complicated problems.
For addressing the above problem; The utility model provides a kind of mounting structure of pressure transducer of multiparameter transmitter; This mounting structure is used for pressure transducer is installed on differential pressure pick-up; Comprise inclined tube road and screw pipeline that the lead-in wire of mounting hole, the voltage supply force transducer of sealing plectane, hold pressure unit passes, said mounting hole, inclined tube road and screw pipeline are opened on the side plate of said differential pressure pick-up, and said inclined tube road is communicated with said mounting hole and screw pipeline; The other end of said screw pipeline and the exterior of differential pressure pick-up, the edge of said sealing plectane and the edge contact of said mounting hole.
Alternatively, the diameter of said mounting hole is 16 millimeters.
Alternatively, the angle of said inclined tube road and pedal line formation is 43 degree.
Alternatively, this mounting structure also comprises short tube, and this short tube is communicated with the other end of said screw pipeline.
Alternatively, the length of said short tube is 1cm.
Compared with prior art, the utlity model has following advantage:
The mounting structure of the pressure transducer of the utility model multiparameter transmitter is owing to offer inclined tube road and the screw pipeline that the lead-in wire of mounting hole, the voltage supply force transducer of setting pressure sensor passes on the side plate of existing differential pressure pick-up; So; The structure that has kept former capacitance differential pressure transducer; The constitutional balance of two cavitys about differential pressure pick-up is former and the balance of medium-weight influence have been kept; Not only guarantee precision, repeatability and the reliability of differential pressure pick-up, make that also the reliability of flow transmitter is high, precision is high, repeatability is high, installation is simple and outward appearance is simple.
