Abstract
A kind of two display pressure transmitter.Utilize the medium of measured pressure to promote piston movement, on piston with scale can demonstrate existing pressure medium numerical value, and tape measure pressure value can realize in the absence of a power supply; Display screen on scale and transmitter body all shows pressure value, and when two numerical value are unequal, user can know that transmitter needs Measuring error.
Description
Technical field
The utility model relates to pressure transmitter, particularly not only has conventional screen display, and has scale to show pressure value, and facilitates diagnostic pressure transmitter whether to have error.
Background technology
Pressure transmitter a kind ofly accepts the instrument that pressure variations is converted to standard output signals in proportion.The physical pressure parameter such as gas, liquid that load cell can be experienced by it is transformed into the signal of telecommunication of standard, carries out measuring, indicating and procedure regulation to supply the secondary meters such as indicator alarm, recorder, adjuster.
Pressure transmitter measurement principle is, the electrode on measuring diaphragm and both sides insulating trip respectively forms a capacitor; When pressure at both sides is inconsistent, measuring diaphragm is caused to produce displacement, its displacement and pressure differential are directly proportional, therefore both sides capacitance is not just etc., high-precision circuit on measuring diaphragm, this small deformation is transformed into the voltage signal be directly proportional to pressure, then adopts special chip this voltage signal to be converted to 4-2OmA current signal or the 1-5V voltage signal of industrial standard.
Pressure transmitter contains high and low two balancing gate pits, and low-pressure chamber pressure generally adopts atmospheric pressure or vacuum.High and low two balancing gate pits of pressure transmitter are passed into the medium of different pressures, the software section of pressure transmitter is after adjustment, and pressure transmitter just can be changed into differential pressure transmitter, can show the pressure differential of Liang Ge balancing gate pit.
But existing pressure transmitter is when occurring pressure error, need to deliver to the detection that producer carries out specialty, whether general inconvenient test pressure transmitter has error.
Summary of the invention
In order to pressure transmitter vivider show pressure, and facilitate diagnostic pressure transmitter whether to have error, the utility model provides a kind of two display pressure transmitter, and it not only has existing screen display, and also has that scale is flexible shows pressure value with vivider.
The utility model solves the technical scheme that its technical problem adopts: two display pressure transmitter comprises transmitter body, transmitter body is provided with Media Interface Connector, transmitter body is provided with sleeve, sleeve is connected with Media Interface Connector, piston is provided with in sleeve, the upper end of piston is connected with scale, and the lower end of piston is connected with spring, and the other end of spring is connected with transmitter body.
A kind of prioritization scheme of such scheme is: the lower end of described piston connects two springs, and the other end of two springs is all connected with transmitter body.
The utility model is when measuring pressure, pressure value can be shown in display screen not only on existing transmitter body, scale also can demonstrate existing pressure value under the promotion of piston simultaneously, pressure medium in Media Interface Connector is larger, piston can by medium push away far away, it is longer that spring is stretched, and the part that scale stretches out sleeve is longer; In the absence of a power supply, scale can measure the pressure value of medium equally simultaneously.The piston spring force that piston can be made to be subject to that is connected with two springs more balances.
The beneficial effects of the utility model are, utilize the medium of measured pressure to promote piston movement, on piston with scale can demonstrate existing pressure medium numerical value, and tape measure pressure value can realize in the absence of a power supply; Display screen on scale and transmitter body all shows pressure value, and when two numerical value are unequal, user can know that transmitter needs Measuring error.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. transmitter body, 2. Media Interface Connector, 3. sleeve, 4. piston, 5. scale, 6. springs in figure.
