Abstract
The utility model discloses an integrated vibration transmitter comprising a shell. The shell is internally provided with a circuit board which is provided with a single chip microcomputer and a piezoelectric sensor. The piezoelectric sensor is attached to an inner wall of the shell. The integrated vibration transmitter also comprises an installation screw which is arranged at a tail part of the shell. The piezoelectric sensor is employed by the integrated vibration transmitter, and the integrated vibration transmitter has the advantages of a long service life, small long term drift, high precision, stable performance and a small size.
Description
Technical field
The utility model relates to a kind of transmitter, relates in particular to a kind of integrated vibration transmitter for monitoring the industrial process physical descriptor.
Background technology
Transmitter be will impression the information such as physical quantity, chemical quantity convert according to certain rules the device of the normalized signal of being convenient to measure and transmitting to, be the ingredient of unit aggregated instrument.Transmitter also can be described as a kind of sensor that is output as normalized signal.Transmitter is divided into integrative temperature transmitter, pressure unit, fluid level transmitter, capacitance object position transmitter, ultrasonic transducer, antimony electrode acidity converter, acid-alkali salt consistency transmitter, conductivity transmitter, intelligent transducer etc.
What generally used the market now is the sensor of magneto-electric, and due to the employing physical construction of magneto-electric, the time one is long, and contained spring is fatigue aging out, causes output signal inaccurate, thereby causes the error of the final output signal of transmitter.
In addition, this book of sensor precision of magneto-electric is also lower.
The utility model content
The purpose of this utility model is to provide a kind of transmitter that precision is high, need not preheating that is applicable to.
The technical scheme that addresses the above problem is: integrated vibration transmitter, comprise housing, be provided with wiring board in described housing, described wiring board is provided with single-chip microcomputer and piezoelectric transducer, described piezoelectric transducer is pasting the inwall of described housing, also comprise the installation screw thread, described installation screw thread is located at the afterbody of described housing.
Also comprise plug connector, described plug connector is located at the head of described housing.
The utility model has the advantage of and adopt piezoelectric transducer to substitute original magnetoelectric sensor, do not adopt physical construction, can be not aging because of the contained spring that causes of long duration, cause output signal inaccurate, so long service life; Long term drift is little; Precision is high; Stable performance; Volume is small and exquisite.To sum up, the utility model is suitable for widespread use.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Description of drawings
Fig. 1 is perspective view of the present utility model.
Embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Shown in Figure 1, integrated vibration transmitter provided by the utility model comprises housing 1, is provided with wiring board 2 in housing 1, and wiring board 2 is provided with single-chip microcomputer and piezoelectric transducer.Piezoelectric transducer is pasting the inwall of housing 1.Also comprise screw thread 3 is installed, the afterbody that screw thread 3 is located at housing 1 is installed, be used for the utility model is installed to the equipment of required detection.In addition, also comprise plug connector 4, plug connector 4 is located at the head of housing 1.Be used for connecting power line or signal wire.
The equipment of required detection is connected with the utility model by screw thread 3 is installed, and piezoelectric sensor is passed to single-chip microcomputer with the vibration signal that detects, and single-chip microcomputer is done analytical calculation with the signal that obtains, and then sends instruction, controls work of the present utility model.
The utility model adopts piezoelectric transducer, and its output signal is passed through amplifying circuit again, high-precision A/D, single-chip microcomputer, DA output 4-20mA electric current.And the employing physical construction of magneto-electric, the time one is long, and fatigue aging can appear in contained spring, causes output signal inaccurate, thereby causes the error of the final output signal of transmitter.Compared to adopting magnetoelectric sensor, the utility model not only serviceable life elongated, long term drift diminishes, precision also is improved accordingly, it is more stable that performance becomes, colleague's volume becomes smaller and more exquisite.To sum up, the utility model is suitable for widespread use.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
