Abstract
The utility model relates to a pressure transmitter, which mainly comprises a capacitive pressure sensor, an oscillation board, a mainboard, a low-pass board, a display board and a terminal assembly. The pressure transmitter has the following characteristics that: the capacitive pressure sensor is mounted on the lower part of a T-shaped metal shell, the leads of the capacitive pressure sensor can be directly internally connected with an oscillation board power board mounted in the T-shaped metal shell, the oscillation board is connected with the flat cable of the mainboard, the mainboard and the display board are mounted in a self-contained small plastic case, and are connected together by a flat cable, the small plastic case is mounted on one side of the upper part of the T-shaped metal shell, which is provided with a transparent glass window, the low-pass board is mounted under the terminal assembly, and the low-pass board and the terminal assembly are mounted on the other side of the upper part of the T-shaped metal shell together, and are connected with the mainboard through a flat cable. The utility model has the advantages of low cost, convenient on-line configuration and much higher interference resistance, and can be better applicable to automation systems with various sizes.
Description
Technical field
The utility model relates to industrial automation instrument, particularly measuring channel pressure pressure unit.
Background technology
Present pressure unit comprises: band HART intelligent pressure transmitter, and the cost height needs specialized equipment could adjust inner parameter, common non intelligent pressure unit, only provide several adjustable steady arms to adjust inner parameter, versatility is too poor, and the two antijamming capability is not high.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned defective, to provide a kind of Installation and Debugging convenient, and low cost is general strong, anti-interference strong pressure unit.
Its technical scheme of dealing with problems is as follows: a kind of pressure unit mainly comprises: capacitance pressure transducer,, concussion plate, mainboard, low pass plate, display board, terminal assemblies; It is characterized in that: the capacitive pressure sensing is installed in T type metal shell bottom, its extension line can directly be linked on the concussion plate power panel that is installed in the T type metal shell from interior, the concussion plate links to each other with the mainboard winding displacement, mainboard and display board are installed in independently for a short time moulding in the shell, link to each other by winding displacement, be installed in T type metal shell top together, band transparent glass window one side, the low pass plate is installed in below the terminal assemblies, is installed in T type metal shell top opposite side together, is connected by winding displacement with mainboard; Described low pass plate includes: filter element is some, one of MiniUSB socket; Described display board includes: button is some, one of LCD display.
The utility model advantage is the expensive HART driver element of mainboard deletion, change a slight Mini USB socket into, increase by three on the display board button is set, behind terminal strip, increase low-cost, the excellent low pass plate of filtering performance, this novel pressure transmitter cost is low, and Configuration Online is convenient, anti-interference improves greatly, more can adapt to large, medium and small all kinds of automated system.

Embodiment
The utility model specific embodiment now is described in detail in detail in conjunction with the accompanying drawings, and as shown in Figure 1, a kind of pressure unit mainly comprises: capacitance pressure transducer,, concussion plate, mainboard, low pass plate, display board, terminal assemblies; It is characterized in that: the capacitive pressure sensing is installed in T type metal shell bottom, its extension line can directly be linked on the concussion plate power panel that is installed in the T type metal shell from interior, the concussion plate links to each other with the mainboard winding displacement, mainboard and display board are installed in independently for a short time moulding in the shell, link to each other by winding displacement, be installed in T type metal shell top together, band transparent glass window one side, the low pass plate is installed in below the terminal assemblies, is installed in T type metal shell top opposite side together, is connected by winding displacement with mainboard; Described low pass plate includes: filter element is some, one of Mini USB socket; Described display board includes: button is some, one of LCD display.
External pipe pressure to capacitance pressure transducer,, causes the capacitance pressure transducer, diaphragm displacement by pilot, changes thereby produce the appearance value, through concussion plate resonance, be coupled out and the proportional voltage of pressure, after conditioning is amplified, send A/D converter, transformation result is sent CPU, and CPU is according to nominal data, user's configuration data, sensor real time temperature data, operation result send LCD to show, send transducing unit, exports corresponding mA electric current.LCD can show pressure measuring value, current output value, pre-set parameter, button can access customer parameter, need use the family parameter instead, the Mini USB socket allows the user to read or revise customer parameter by serial communication mode, low pass plate filtering performance excellence, improve the whole anti-interference of this novel pressure transmitter greatly, make its steady operation in rugged surroundings extremely, make the user can be, enjoy the convenient of intelligent pressure transmitter, and pressure unit class and reliability all get a promotion with non intelligent pressure unit cost.
